I'm looking to compare notes on the 102mm LM cars. I'm currently playing around with two of them, a fully hopped up 962 with stock dps and a mostly stock 787. Both cars run great and I can turn some fast laps but I still get lots of chatter from the rear of the 962 during high speed turns.

Specs:
962 LH
PN Speedy 07 motor
Atomic 1 degree knuckles
Atomic tie rod 0
PN 102mm V3 motor mount
standard ball bearings
Kyosho ball diff with titanium shaft and ceramic bearings
Kyosho medium carbon h plate
Stock DPS

I have tried various combinations of Kyosho 20 and 30 degree tires. I get less chatter and hop from the 30 degree tires but it still exists.

My goal is to completely smooth out the rear. Any thoughts?

My 962 is very somewhat similiar in parts:
1 degree knuckles
1 degress camber
Atomic StockR
Atomic LM motor mount
Atomic Titanium Diff

I'm not sure if you're looking to go as far as we did, but me and Ianc have "bobbed" the tails of our 962 to make it handle more like another friend's no-wing Mazda. The car becomes much more more responsive at higher speeds and at least appears to settle the rear a little.

Are you using LM tires? Mine with LM tires all around and a similar set up except for an oil shock doesn't chatter at all unless I chop the corner. There does seem to be a little more steering with the 787 plus the ability to slide the rear a little. I found that adding the IMSA version 962 front wing took care of the steering issue while the KH rear body section gave the rear additional bite.

I am using LM tires, when I switched to 30 degree tires it smoothed out noticeably but there is still chatter. I don't think I need more bite in the rear, I thought the chatter was caused by the tires having too much grip and breaking free. With 20's the first several laps are smooth but as the tires warm up and get more grippy the chatter starts.

I also noticed that the KH body is somewhat smoother.

When you say IMSA front wing what do you mean? I know what IMSA is and I know what front wings are but what are you referring to here in regards to these bodies?

Thanks!

MLeemor60, do you have any pictures of your front wing set up?

Some of the IMSA versions of the 962 had a front wing. I'm assuming he set up something like what was on the original which is linked below:

Wow that's ugly, I have never seen that before and I thought I was a 956/962 guy.

I won't be making that out of sheet plastic and gluing it to the front of my car :D

Its bold step to take, especially to a great looking car like the 962. I have a an extra white body I may try it with. I'd love to see how his looks.

That is the one. Good shot of Bob Akin in the Coke machine. Just start with a narrow piece of lexan servo taped across the headlight covers. Play with it til you get what you need with no damage to the body. I am currently using it on a mule body for possible adaptation to the 85 Sebring winner.
