My SWB car (86/90mm) is my "stock" (PN70) car. In the rear I am running an Old Atomic Aluminum RM motor mount, Kyosho MZW216 dampener, and a Kenon #3 Carbon T-Plate (MR3005). I have found that it is fastest running the disks pretty much dry but I did sand them with 1200 grit paper. This T-Plate is pretty stiff vertically but pretty soft in roll but after trying different plates I always come back to this one.

In the front I am running reversed King Pins with MZW416 Inner Tube front suspension with a tiny bit of 10wt shock oil.

As I mentioned when I run this car with the 90mm bodies I run a wide front and on the GT3 I run 0mm offset wheels all around, narrow in front and wide in the rear.

When I first started running this car at short wheel bases it was pretty darn bouncy so I started looking at ways to calm it down and the MZW216 helped. I also had a pretty bad issue with traction rolling. I did a bunch of reading and tried a bunch of stuff. I run the most worn set of front tires I have, I lowered the front end about .2mm, which also resulted in less camber curve, and found a cheap set of Kenon "Low Down" knuckles (MR3032). I can now drive the GT3 and GT1 as hard as I want with zero traction rolling issues on my Mini-96 track.

I just received a Porsche 934 body so I am going to convert over to 86mm and a narrow front end, the set up will remain the same with the exception of using the Atomic MR03-017-2N which increases the caster. To be honest I have always been a bit confused with how caster works but it has something to do with the camber change as the wheels steer, but EMU suggested going this route.I have not run any 86mm bodies since I pretty much eliminated the traction roll issue with the 90mm bodies so I am interested in seeing how they go.

Cheers,
Jim
