Ive had a problem with my car pushing. When i built the car i put my 16 gal. fuel cell towards the left side of the car and i also add weight to the left side, is this a possible cause of my bad push? Should i put it in the middle and add weight to the left or what? I also run the same # springs in the rear should i try a spring rubber in the left? Thanx in advance!

Does the car push on entry, apex, or exit? If it pushes on entry, does it have a good apex and exit? Or if it pushes on exit, does it have good entry and apex? Are you on or off the brakes on turn entry? Do you have or can you use a brake bias adjuster? Can you use aftermarket springs and shocks? I know that I have not answered your question, but there many potential cures for your problem, depending on where the push exists.

the people i've asked about rear springs have told me to keep about a 50# difference in them and to have the harder one on the left side.i also have weight jacks in back and i have been amazed at what one or two turns on those will do(bigtime difference). as far as weight,ive been told that you want between 51-54% of your weight in the rear when scaling the car.also,tire stagger can greatly affect the inside/outside bite.

First, I'm not a chassis guru so take everything with a grain of salt. I just know what works for me. I'd try all the easy things first. By all means try the spring rubber it is easy and won't cost you anything. I would have a tendency to try it in the RR though since you have a push on exit. I would also check the rear for square, if you have lead in the RR that will tend to make the car push on exit. Make sure the rear axle housing is not shifted to the right, or left for that matter. You probably have to run DOT street tires, but I would try a little more stagger. That should do two things, decrease cross weight a little and help the car turn better on exit. Hope this helps.
