I remember reading a post by Mark sometime back. Much more than beefed up sway bars!!! If my memory serves me correct, he has thousands in the suspension. Curious to know how it did too. Chime in Mark and let us know.
List of modifications to the car Mild Cam TA Headers Global West upper and Lower Tubular Front control arms Wilwood 13" Front Disc Brakes (4 piston) 580 lb spings in the front Koni Adjustable Shocks on all 4 corners Metco Motorsports Adjustable upper controls arm in rear Metco Motorsports Billet lower control arms 17" x 8" American Racing Torque Thrust II wheels with 245/45/17 Bridgstone Potenza SO3 tires on all four corners Hotchiks Tubular 1 3/8" front sway bar Remove rear sway bar I did not do as well as I hoped I would. The course was really setup for smaller cars and I have too much weight to be competative. I think to be really competitave I need to get the car down a couple inches, put 17"x 9.5" in the front and 17" x 11" in the rear with real road course tires, Stiffer springs in the front. And Fiberglas fenders, hood and bumpers. Maybe someday I will do a clone GSX and try it. Mark
