I run an 85 Olds Cutlass on a 1/2 dirt track and coming out of turn 2 and 4 my car seems to porpise a little like I might be driving in too hard and the front right tire is getting too much bite. I am not sure if it is an air pressure problem or a camber / caster problem. Suspension for this 3400# car is lf1000, rf1150, lr300, rr250 and I have Pro Shock shocks on the car. I do pretty good in the corners but I think I could do alot better. Tire pressure I try to run are rf - 15 ,lf-14, lr-11, and rr-13. I would appreciate any input you might have! Thanks, Kent

I think driver 27 is right about the tire pressures. You are probably using DOT steel radials. If So start at 22 lbs on the right front. Then drop 2 lbs from there going around clockwise. 20 rr, 18lr, etc. Set the toe at 5/16" using toe plates 30" long. The rear springs could be softer, say 250 lr and 200 rr. Stagger should be about 2". Remember, Your are there and I can only give my best guess. SLEEPY

a little more split on your front springs might help too i like no less than 200# on mine my first car did the same thing i had the stock deisle springs in it and look the left out and put a regular v8 spring in helped a bunch no more bouncing

We use the IMCA 15x8 all American Racer G-60 tire in my class. It is the track tire. I do run tubes in these although alot of people do not. Thanks for all of your replies! Kent
