Last night i stretched my wheelbase out to 102 mm to try to accomodate running the Big Mc and the Mazda 787B and Porsche LM bodies...the porsche fits fine, but the 787, it hits the mounting point for the rear spoiler with the motor mount. Just curious to run this body do yall just run a larger spur gear so the motor mount can shift forward or do you trim the motor mount (possibly a newb showing w/ asking to trim the motor mount).

I would just like to gain clearance to run this body. I did do some searches i couldnt find any pics of anything being shaved or anyone else w/ this issue before. Sorry if my green thumb is showing right now :o

Shouldn't have to shave anything. What pod are you using

I have a PN motor pod...I should have took pictures last night of how it's hitting, i'll take some tonight and post up

I have seen the spur hit the lower part of the Mazda wing before. But a small amount of grinding takes care of it.

this is the actual motor mount itself hitting the mounting point for the wing, kind of boggled my mind. i know my mount is set all teh way back, but it's perfect at the mount for the gear mesh. the spur gear itself seems fine

I've trimmed my Mazda 787 a bunch to get it all to fit out right. It's cut for 98mm, I've raised the clips into the body to get a lower stance, trimmed the vents in the back to get clearance for the motor mount too. The rear wing was swapped for a Lexus SC430 wing mounted directly to the body.

I had pics on here... I'll see if I can get some on again.

Well it's not the vents creating issues, but i'd like to see what you trimmed

this is where the motor mount is hitting the spoiler mounting point

everything seems fine, super tight fit, which is just like the Porsche body, just at that point, it hits :mad:

one thing i an tell you is the tri shock will never fit under that body. unless you cut real big holes in it. as far as the pod hitting i dont believe it will even go to 102mm i think its only 100mm. best pod to use for that is the older pn 98-102 pod or the new pn 94-102 pod. they are alot lower of a pod and will not hit the body. i have one i can let you use if you want or sell real cheap

That's what I run on mine, the old PN 102/98. I got pics but I won't be able to get them on tonight. I dremeled those posts out of mine, the wing is mounted through newly drilled holes on the top deck.

Oh, and I just run a disk dampener only on this one. It is one of my best runners, it's always a toss-up between this and the 599.

i swapped out to the disc damper setup, so i know it's not that, even removed my dual spring for the oil shock, so i know that's not hitting. i adjusted the t-plate back one hole and shifted teh top plate back one hole. the porsche 962 body it fits perfect, but it hits that point as shown in the pic on the mount. the pod i have is the 94-102, i believe. i'm going to try one more thing i just thought about, if that doesnt work, i may have to find another option to run a different rear spoiler. if i make it out wednesday i'll see what you have though

The pod you have is the reconfigurable. 94,96,98,100. The one I am taking about is all aluminum no carbon fiber

Sammich

ahhhh...i'm going to see where the wheels sit at 100mm, hopefully that'll grant me clearance, which i doubt

Why not just put it back to 98 and run a pan body in the can am class

Sammich
2013.01.08, 10:49 AM
i still eventually want to run the body though, i love the 787 way more than the Porsche body and pan bodies...i'll see what happens tonight though with how this 'idea' works.

It looks like its barely hitting. Trimming the post, or finding an alternate way of mounting the wing (I can show you a few) are both options. What I see as the most logical solution is the trim the end of the motor holder. The extra material behind the slot (where the screw mounts) has absolutely no purpose what so ever. It looks like you've got a few mm of material sticking out beyond the mount, while the slot is no where to be seen.

i was thinking about grinding off some of that mount, but i didnt know about the durability of it, especially after the talk we had sunday about how these crack. if that one option doesnt work, i'll trim it tonight, if i can find the right extension on my dremel tool

The durability of those is questionable at the slots, and I've only seen the break at the forward one (which makes sense because of its proximity to the motor, which is what enacts force upon that area). I would keep a little material behind the rear slot, but you don't need all that is there.

sounds like a plan :D

Sorry for the delay, here's what I cut up on my 787:

There is a bit of a mod to the middle for clearancing the disk dampener, I used to run a top shock on this car too:

http://mini-zracer.com/forums/picture.php?albumid=88&pictureid=1557

http://mini-zracer.com/forums/picture.php?albumid=88&pictureid=1556

Notice the vents too... relocating the side clips up into the body, going to a 98mm, combined with this type of mount made it a necessity to remove some of the material on the top vents:

http://mini-zracer.com/forums/picture.php?albumid=88&pictureid=1558

Had to modify the nose vent a bit to for clearance with the A-arm front end on my 02. I ground the corners a bit and gave the whole area a bit of a heated push. not sure if it's easy to see in these pics

Thanks for the pics, i greatly appreciate it. I did the grinding back of the motor mount itself to find out that it's still going to hit the motor pod anyway..i'm going to see what pod chad has and make my decision from there to see what else i need to do, if anything

try atomic lcg v2 if you dont use a dps for 98mm.
try atomic lcg v3 if you use a 98mm dps.

Hi,

I have been running a Mazda 787b for a couple of years in our club LM class.

I use the PN Racing reconfigurable motor mount (part number MR 2999) with the LM carbon fiber set (part number MR 2888CF).

I did have to cut the end portion of the motor holding part, with no impact on performance. I also had to dremel a small portion of the rear diffuser for propoer clearance.

See the pictures attached for details. I have never had a problem with this set up.

I hope it helps.

LOVE IT...see you still retained almost the stock look of the 787, which is what i want to do. i'll have it all figured out before the weekend is out of exactly the route i'm going to take. had a discussion w/ my 'mini z mechanic' last night :D
