Slightly tailhappy... Options

[falcor75]

I need to learn a bit of how to setup my car better.
Its got new Bilstein shocks all around, new bushings everywhere.
Front has the stock torsion bars and a Tarret adjustable swaybar.
Rear has 140lbs Weltmeister springs.

Last year I ran it with no rear swaybar and the front swaybar set at about 25% from the outer most position. This got the car quite tailhappy when doing autocross/slalom events.

During the Winter I added the stock rear swaybar just to see what difference it made and it calmed the tailhappyness down a bit but still a bit twitchy.

Whats the next step? Decreaseing the front swaybar setting?

(IMG:style_emoticons/default/agree.gif) Once dialed in, small changes should be able to be made w/ tire pressure adjustment. But, it doesn't sound like you're at the point of 'dialed in' quite yet.

What size bar are you running in the front? 140lb rear springs, no rear bar, stock torsion bars and a 19mm front bar is a good combination. You should be able to run the front bar at mid- to full- stiff (drop link adjusted closest to the sway bar) to relieve your over steer.

My experience w/ a reasonably stock car was using stock rear springs, a stock rear sway bar, stock front torsions and a 19mm Weltmeister front sway bar (set up for SCCA stock class). With this set up my default tire pressure was 26psi front / 29psi rear.
