View Full Version : Just How Important Bodies/Offsed Really Are:

MR-01/02
Offset is extremely important in my eyes. I've found that wider offsets in the front tend to be more stable, but you give up steering in the process. I'll take some extreme examples so that this is understood easier:

575 GTC. Offset in front: 2.5 Rear: 3.0
This is the widest offset for a MR-02 that I've seen. The atomic VDS has 3.0 all around. But that isn't a Kyosho body, and it usually isn't allowed in a stock class race because of its physics of shoveling cars off of the course if you don't know what you're doing with it LOL.

Now, the 575's body is generaly heavy to begin with. Weight on tire usually means grip. So you'd figure that it has good steering, but this body just has great stability, and not much steering because of its wide front end.

Picture a tricycle, and a Quad. If the Tricycle were to go as fast as a Quad and turn full steer, which is more likley to flip? Definately the Tricycle. Because its front wheel, is smack in the middle, and this will cause more LEAN.

With that said, say you take a body such as the Mucrielago (I'm convinced this is God's gift to Kyosho and all Mini-Z'ers) This thing has 0 front offset, and 3 rear. This will yeild the Tricycle effect and give you the most steering, but because the offset of a MR-02 is wider in the front than a 01 given the same wheels, 0 offset in an 02 is plenty of stability. And considering that it has 3 in the rear, it is VERY stable on collisions and turns. Not to mention, you can run Enzo offset wheels on this flawlessly.

A body close to this is the Enzo. Only difference is that the Enzo's front offset is 1. But everyone has Enzo's that's why I went the Murcielago route, and I'm glad I did. Ever since I did, I've seen that body's reputation populate like a multiplication table.

One of the lightest bodies I've found that Kyosho makes is the McLaren. However, this thing has 0 offset all around. If set up properly, this thing can handle like an animal. But it's horrible on collisions.

Also another thing that me and EMU noticed was that not only are the White unpainted bodies stronger and more durable, but they are LIGHTER. And if you have read any of my Threads, you'd know how me and EMU feel about light cars. It's the only thing you can do (lightening) to improve power/handling/and braking all at once with one job.

Weight is important, but shouldn't be first or last on your list. Just worry about wheel safety, and offset. Here is a neat way of lightening the top end of your body: Lexan Windows :D

again, i agree with everything you've said.

i run the 575gtc for the stability it offers.

you should also check out the testarossa. i think it has the same effect as the murci (to me anyway). i currently run the 360gct, 575gtc and testarossa :)

i like the tricycle comparison :cool:

EMU has a Testarosa, yes, that thing definately has a good turn in and rear end stability. I'd love to see one painted, he has a white body. If yours is painted, link me. Because in white, I don't think they are very apealing.

what do you think of the 360gtc btw? i happen to think it's fairly nimble, obviously not like a mclaren but pretty even none the less.

LOVING the paint scheme. Are you going to put decals? As for the 360 GTC. I find that to be near the top of the list for AWD's. That thing seems to (for some reason) drive very predictable. I guess because it's short. It's a tad wider than the mclaren, which basically means that it's a better handling version of the mclaren. You may want to try to put 0 offset in the front. (if your running it on a mr-02). Many people I know shaved off that front lip. I own one, drove it a few times, then tucked it away into my showcase. Sturdy body. Not as sturdy as the plain 360. But definately tougher than the ever so fragile 575gtc. I've re-enforced the heck out of mine by crazy glueing areas that are known to chip/break/crack. Again, that ones in my showcase, I don't drive it anymore. I keep them in mind condition. -the yellow collection- I'm sure you've seen it.

MagicMan
2006.04.04, 09:09 PM
Arch... The Testarosa is 0 in front and 3 in rear and a RM correct? If so, do they make them in Yellow? ;) I believe a shorter wheelbase from the Murcielago will give more turn in as well. My setup is so stable, I wouldn't mind trying it out considering that I have the ML damper and mount.

The only one that I don't have on that list that you named is the plain 360 in yellow. But once I got the GTC, I just didn't bother searching. I came across a B+ condition C5R the other day. In a mr01 chassis with MINT wheels. Bought it for 60. Put the body in the showcase. I'm happy because I'm using my other yellow one for the AWD.

Ask EMU about where to get bodies, He's the one that always helps me with getting things.

are you aware of any other 'tricycle' bodies?

LOL at tricycle. Not off the top of my head, but I'm sure when EMU see's these threads tonight, he'll reply to this with every body that has that effect. His offset chart should tell us actually, I'm gonna go get the link to his post and paiste it here:

Another good topic.

I personally just got a white body 360GTC and shaved the lip off to run in the HFAY OLPS on my MR-02. I had been running the 575GTC and loved the stability after finally got it setup right (including using an Atomic 94mm MM motor mount). But after HFAY OLPS race #5 I decided I needed to "risk" going with something lighter and skinnier than the 575GTC to have a chance at better HFAY OLPS results. We'll see how this turns out for me.

Another note in picking a body is the color(s). Personally I have found on a black RCP track that I need to run a light colored body (white, yellow, green, etc.) or put white stripes on a darker colored body (red, black, etc.). This helps me pick up my car and the direction it is pointing much faster against the black track (it probably doesn't help that I'm slightly red-green color blind :eek: ).

Yet another thing to consider in picking a body is the front nose/bumper and rear bumper. The size, height and angle of your front nose/bumper will determine how easily you will pick up (and wipe out) another car when you come up behind it. Conversely the size, height and angle of your rear bumper will determine how easily someone else will pick you up (and wipe you out) when coming up behind you. I personally think the 575GTC has the best front and rear bumpers. Related note that I shaved the bottom lip on my 360GTC like most other people do because it tends to get stuck in the RCP foam side rails.

In regards to weight note that in this other thread (http://www.minizracer.com/forums/showthread.php?t=21180) stepchild weighed a couple different bodies and found the following:

Mclaren Gulf=33.7g
Enzo-37.3g
575 GTC=43.9g

A full MR-02 with batteries and body typically weighs about 175g to 190g. So the 10g difference in the Mclaren body vs. the 575GTC body alone amount to approximately 5% of the total weight of the MR-02 car.

Again as MagicMan stated, lighter is not always better. Especially if there is more bumping and crashing going on.

Great insight. I find rounded/angled noses are best for cutting turns, because if you graze them, they are more forgiving. The length of the rear matters as well for swingability. And as you stated, it does matter its shape because if someone rear ends you..... you could get some serious wreckage. I find the Mucrielago doesn't take rear ends nicely. It stays straight, but sometimes the front clip will come out.

What I tend to do to ALL of my bodies, is purposely break off the side clips, and then re-glue them visciously with large amounts... Now be careful, if you don't get this glue job correct the first time, good luck not ripping your doors off if you need to get the clips out the second time. The reason that I do this is to rid of some of the chasis play that some bodies have. Murcielago is notorious for this, so is the 575gtc, I'm sure there are many more as well. But reguardless, even if your car doesn't have the play problem, you should do this as to it will be harder for your body clips to come out of the chasis during a colision. Also will give you a more sturdy stance, and prevents the front nose from coming out of the front clip on some MM cars with a huge rear that folds on a rear end.

Hope this helps... Once again, keep up the great insight.

Obviously you can allways run wide bodies with more narrow fronts... Some people that I know use 0n front on the Enzo with 3w rear (and he is usually the winner, but of course his driving is incredible)

The majority of my bodies are white bodies, so for the wheels I use various offsets that usually are not the stock ones, I find what I like best and stick with it. I have a bunch of different offset Atomic wheels for sizing, and I too like magic use the triangle effect for most of the stock class bodies.

Triangle club
98mm
Murcielago 0n/3w
Diablo 0n/2.5w
*Mercedes/Mclaren SLR 0n/1.7w (these are the offsets that I use on my 33.6g SLR body, C5R rear wheels)
Ford GT 0n/2.5w

94mm
F50 0n/2w
Testarossa 0n/3w
*575GTC 1n/3w (preffered stock class offset, for modified I use 2.5n CLK wheels up front)
Calsonic/Motul 350Z 0n/2w (for MR02's wheels rub at high speed sweepers, so shaving the body may be required, on AWD its perfect).
Corvette C5R 1n/3w (one of my best handling cars almost took 1st A main in its 2nd race)
Possibly the Lamborghini Jota. I have not test fit this on an 02, but it may work since it is 1.5n/3w on an 015... Ill have to get it to test :p

90mm
F40 0n/2w

That pretty much wraps up the triangle club... of course, you can still use the effect on alot of bodies that have less offset... like the 360, using 0n/1.7w (I think that 2w is a little too wide for that body, but the C5R wheels fit very well, magic almost took home a points series with the 360 with those offsets, NSX BBS front wheels and C5R rears ;))

My favorite 98 body is the SLR, it is VERY good on collisions, barely gets knocked off line, and is very good on the rails, you can almost hit it head on and you will get straightened out rather than spun around. I havent used the Murcielago yet on a large track, but will soon :D Enzo is good, but not too good on the boards with its super long square nose.

For 94 bodies, C5R, 575GTC and 360! I shaved the front lips to round the corners a bit so they dont hang on the rails. Testarossa is good, but a bit heavy even in white body form. All of my other bodies are sub 35g, Testarossa is about 37g...

For 90, F40

For AWD 94, Calsonic/Motul 350z#, Testarossa*#, F360, C5R*#
For AWD 90, F40*#, RX7 FD3S, 911 GT3R

Well I purchased a 575GTC because I found it most attractive to my eyes. I see that is is a bit esoteric in design though since it has a very wide offset for its wheels and is an RM design. IE parts are difficult to find. I purchased this car as a bit of an afterthought for something fun to do but now I am hooked... so...

I purchased some 2+ and 3+ offset front wheels as a test because I can't find any place that has 2.5 in plastic. I guess my question would be. Is it absolutely imperative that I use 2.5 with this body or am I really missing out either running 2+ or 3+ on the front?

Really appreciate any feedback.

EMU

Running 2mm front wheels keeps the wheel slightly inside the wheel wells, which will protect them over time from impacts. I am running 2.5mm front wheels on my 575GTC white body (non original wheels) and my chassis has some cracks on the shock towers, and occasionally I will loose a tire off the front wheels from an encounter on the wall.

3mm front wheels are a little too wide, or at least the Atomic ones are. I have found that the Atomic wheels are a little wider than the stock wheels by maybe 1mm.

If you have 2mm wheels, you can allways put a little shim between the bearing and the knuckle to increase the offset slightly. Although 2mm would be my preferred offset for this body.

HammerZ
2006.06.11, 12:58 PM
I bought a full set of the Atomic wheels just for fitting different bodies and such. At $26+ shipping I think it was a good investment. This way I can see what would work and what will not. They are good for getting you in the ballpark.

The one part of the stability therory that hasn't been hit on here is COG or center of gravity. The overall boddy weight does make a difference but I have found that my ultimate body setup is NOT one of the wide bodies but rateher one of the narrowest, the Iwaver Saleen body, which I run with 3R -1 fronts and -.5 rears....odd but this is the most stable body I run and the reason is that it is the lowest body available,it is also very light making the COG very very low. It even sits lower and weighs less than the McLaren (mt second best body for MM) I also believe that the extra length coupled with the low ride height add to the stability of this body. It is also a demon on the track when it comes to bumping and grinding with other cars or the railings.

EMU,

great post. I run AWD 94 using both Calsonic and F360. i personally like the Calsonic better. i run it on a 3.5N and 1.0W. I just wonder why running on a 0N and 2W is better? (sorry if this is a dumb question, i m new to this hobby)

Thanks,

Unless you do a Miami Vice theme like I was going to do. But I figured that was too easy. I've actually found the Testarossa to slide it's rear out a lot.

guys...here's a pic of an orange testa I did after reading this thread....

I'm gonna try it today....will post here tonite..my previous body was a lexus 430( 0 front and rear...)...could never get the thing to turn, if I set it up like a touring car..and not a jittery mini z...


also, I put a piece of lexan in place of the motor cover.....I'm gonna put some lettering on it so people know its clear.....

I started using the Mercedes SLR.... fantastic body. And then switched to the 575GTC with which I fell in love.

Anyway I have tested, 360GTC and later the F430. But this last one performs much much better than the 360GTC, being almost similar bodies.

The Testarrosa is in the shelf waiting for the 575GTC to retire. something that I keep intending to do.... but never happens! :rolleyes: It had it's testing days and did not dissapointed in any way. Magnificent i would say. I even lifted the motor cap in the front to make a little "air intake" right after the rooftop.

About the McLarens and the Enzos. Both are great bodies. McLarens are fast but horrible in crashing/fliping etc. Enzos tend to show as low and flat and long that one thinks woow this IS the body, but besides I don't like it's looks, it a great ride. Specially to fast drivers.

I recently tested almost all of this bodies on the same chasis setup (94mm & 98mm using the Atomic MM motor mount) and by far the SLR was my favorite.

A new kid on my block, is the GOLF. It's now on my AWD. Fantastic fun to drive!!!!

The triangle club IS the way to go. But then, you can play with steering shaft lenght to make the wheels give you more stability on straights or more drivevability on curves.

I prefer to consider bodies as a way to modify the COG of the package. Sometimes adding a little weight in the front make the car be totally different. Some time ago there was a heated forum about wings and aerodinamics. But no one mentioned the way back ends of the cars are. Why have the Corvettes Amazing handling? Or the 575GTC? I'd take a guess on the rear air difussors they have, but....... I'm sure this could take a whole new discussion.

Offsets are important. Bodies not just fix the outer limit to what you can try. They're not tied up one another. Be creative. Drive and test. That's the only truth.

I have found that the front overhang on the body is a little long, and the steering feels a little delayed. Similar to how the enzo handles... It was a good setup for me at the time, however now I am running the corvette c5r and just got the SC430 white body to try.

With the SC430, did you reposition the body clips to give the rear end more clearance?

hi guys...


I ran the tetsrossa body today.....And found it to be better than than the lexus......


I ran the car at Cruisin RC's in waldwick, nj....an RCP track, that is not REAL big, but does manage to have a 10 foot strait, and a real carvy infield....


First thing I noticed was that the mirrors get hung up....a lot. So off they came, and it was way better...


Also, I wasn't used top the square nose on the car, vs the Lexus, so that took a few laps( like 2 hours of running:D) to get used to...



BUT, once I got used to the car, I really like it.....it definitely carved it's way through the infield.......and was just as stable as the Lexus on the back straight.....


I ran the same set up as the lexus.....I try to tune the mini z's like I tune my pro 4 and r40 touring cars.......a little harder in back, with the same or softer in front.........I want the cars to NOT be that bouncy, jittery feel that mini z's have...you know, where you think you have a TON of steering, but all you are doing is fighting a twitchy car........


You need to slow down to make a corner, but the car runs real stable, and controllable........I need to get a little more off throttle, higher speed steering, but all in all, it runs great...



after a couple of hours of running, a few of the guys showed up....some good guys that run in the a sometimes,( as I do)...but are squarely in the top of the B every race.....All running Corvettes, lexus, red bull audi, and mclaren GT's...


the testarossa was easily faster through the infield....and plowed through those that were wrecked.......very unflippable.....so I'm gonna leave it as is till fri race day....


The only problem I had, really, was the paint took a beating....


I used the tamiya primer, tamiya spray orange, and tamiya clear.....and gave the car Plenty of time to cure after the final coats.....but it still chipped on heavy contact.....

any ideas?....


thanks

hi 575........I have to be honest, it was only a few nicks and scratches....so I popped some spray paint in the cap and use a fine brush to touch it up......I've had the flu since last week, ao I haven't tried it in competition.....

Does anyone by you run an Atomic wing on a testatross?....

no one has the testarossa at our club sadly:( we use enzo's and maclarens usualy are the main bodies, i use the 575 with enzo offsets btw, turned down the responsiveness on the kt5 and the thing drives like a dream, so responsive!

I have tried the Lexus SC430, and I cant get it to hook up at all with the 94mm MM config at my local track. If I change the front tires to a harder compound, I push too much. This body is only suited for high grip tracks. Which my track is not. There is good front end bite, but poor rear bite. In an RM configuration, I think this will handle very well. It is the most aggressive 94mm body that I have driven, second is the F50. I ran the SC430 after a race at the DOW track in PA, and it ran very well. Made me wish I had run it during the race. Turn in was faster, corner speed was higher, and I had no traction loss in the rear end.

The Testarossa is alright, but I dont like the long front overhang. It had early praises, but is not competetive enough with low rear grip. In RM, it should be a very stable body, with decent front bite. The 575GTC is too sluggish for me, turn in is a little too slow, and corner speed suffers. Stability is very good, but the car doesnt want to rotate.

I have recently fallen in love with the F40 all over again. I had previously sold my old F40 whitebody. I used to run it a bit in the 90mm RM config. It was good, but it would flip if driven too aggressively. I hope it still gets use, I miss it. I ordered a new ASC, shaved out the rear wheel wells, and am running in a 94mm MM setup.

The chassis I was using had too little rear bite at my local track, I had set it up for use at a different track where there is more rear grip so I used gear diff, 10d PN front slicks with 20d Kyosho slick rears. 0N/1W (I use that offset for all of my 94mm MM bodies now). Regardless of the rear tires, coming out of the corner the rear would wiggle loose.

I have been running the trusty vette for quite a while now. My vette has a ceramic ball diff and PN 15d slicks. It runs well allways in the top 4 this past point series. However, I felt that it was lacking a little steering in the slower sections of the track. If I put the 10d PN slicks, the rear comes loose even after they wear in.

I put the F40 on the first chassis (which is actually my back up), and put it on the track. I havent run the vette since. The body has more rear stability, rear end is planted and doesnt squirm as much as the vette does... Mind you, the F40 chassis has a gear diff, while the Vette has a ceramic ball diff. I was blown away. I wont really recommend everyone to go out and buy the F40, it probably wont drive as well for most people since the track conditions are different everywhere. It works great at my local track, since it has such good rear stability. And I can use higher grip front tires. I will be trying it at the Atomic East Coast regional race, amongst many other bodies to see what works the best.

Since we are using handout tires at that race for stock class. I am going to use different bodies to tune my cars handling attributes. My base will be the Corvette, if there is too much push, then I will switch to the Lexus. If there is oversteer, then I will use the F40. I have a few other bodies that are in between, Audi (good for low grip, was the body on the F40 chassis before), F50 if the lexus is too much... It all depends what the grip is at the track. For modified 2wd, I am going to use the Murcielago! Those are the only classes I am running... dont want to spread myself too thin. Handout tires are a new thing for me, so I need to figure out new tuning methods. At other events, I would do all my tuning with tires.

This year we changed our track surface. From carpet to rubber. It was a huge change!!!! We have a "very high grip" surface now.

We're still struggling to find the right setups. But one of the guys that's really doing great drives a Lexus. And he has fitted the "inverted triangle" in the wheels. This is, wide offset in front, and narrow in the rear. The car looks ugly, cause the rear wheels appear to much inside the body, but the handling it has it's impressive.

My self i drove the F430, and then I debuted my Testarrossa. After a while the F430, went back to the shelf and the testarrosa took it's place. A 94MM chassis it's has great handling with the proper tire F/R balance. But anyway it still lacks of cornering speed.

My other chassis has my old 98MM Mercedes SLR body. Beautiful. But also with this one, my cornering speed suffers.

I will test the "inverted triangle" on the wheel's offset, and see what happens.

Anyway, the 575 is not yet happily sitting on the shelf. It's screaming to get back on track again. I guess I will have to give it a new chance and.. get a new one to replace it.

I'm likeing both my Modena RM with 0 offset all around, and my Murcielago MM with 0 Front 3 Wide. Will let you know which handles the race track better tomarrow night after race day. Both are fun at home, but Mini96 too small to really let'em loose and make go fast turns. I find the Modena very stable!

thought I would bump this up, see if anyone has any new additions to the "T" club, with all the new bodies coming out...
