I wasn't sure either, so I found this. Start with post #1614

Hopefully this what you're looking for.

Thanks for the input, guys!!! The Avid motor centering kit will be my next purchase!!!

That did help thanks, those are the ones I chose by default, but never knew the other offset sizes.

I'm changing out the rear tower and arms to carbon. Should I change the u brace to carbon as well?

Look at the towers the graphite composite tower is different than the b4.2 stock tower. Most guys just use the graphite arms ,top plate and the u-brace.

What is the difference?

I thought that was just the front towers.

Most of the team guys will run Carbon Front Arms, Front Shock Tower, Front Upper Brace & Rear U-Brace. We also like the 2 hole front caster blocks as they are made from a harder material.

I personally run the standard front arms during the winter at some of the indoor tracks because here in the midwest it tends to get cold and the carbon front arms don't like impacts with the temps are down...

I sometimes run the B44 rear arms if I need to free up the rear end a little.

The carbon parts stiffen up the car a good bit making it a bit more responsive.

The guys i know use the b44 rear arms and stay away from the carbon. They say the carbon is too stiff.

The carbon rear tower is wider. That sucks. That's 9 bucks wasted. And in soldered my motor for nothing.

Hey guys,

I've been running my B4.2 with the kit setup for awhile now in mod 2wd with a stick pack and non-center mounted electronics. I haven't touched the setup, and it has been absolutely perfect at all of the outdoor tracks I race at.

Breaking news: It's cold. I've moved indoors for the remainder of this year. I have ran into some setup issues for once. I have no experience running on a higher grip surface like this and I am a carpet racer.

The track has had diesel sprayed all over the surface. It's hard as a rock with no dust, but has several cracks and bobcat tracks permanently in the track surface.

Here is the track completely green, first run:

I ran the other week there with the preferred slick tire. It was okay, but I could not get my car in and out of the corner with ANY corner speed, or get on the throttle without popping wheelies. The car didn't carry enough momentum to roll at all when turning due to the slow speeds and stiff suspension. My car was incredibly jittery going across the bumps as well, almost like it had a rigid suspension. Keep in mind that I only slightly use the brakes and attempt to carry as much corner speed as possible without blowing the corner.

I believe I should start with softer shock oil and removing .5 degree of rear toe. Should I look into any roll center or complete spring changes?

Any help is appreciated.

Also, are you guys running the wing spacers with the jconcepts wing mounts? Thanks.

not really... just drill the extra hole, and dremel the clearance for the big bores..

Try moving both your shock mountings to the inside and reduce your droop.
