My buddy's car is doing something that has me baffled. His car rolls to the front super hard when he gets off the gas for the corner but also does the same thing coming out of the corner-rolls to rear real hard. He has a push going in and it appears to me that it is rolling so hard to the front on entry that it is over loading front tires causing the push. He has pretty good bite coming out but the slow entry is hurting his times due to having to wait on car so he can get back on the gas. Is the cure as simple as heavier front springs? He now runs 900 and 1000 on front. His rear is 225 and 200. He runs in a SuperStock class(which I beleive is almost the same as I-stock) and his car is the only one doing this. Another thing I noticed is that his rear springs are not mounted on top of rearend like mine but are actually mounted on top of lower trailing arms.(we both run metric four bar rearend suspension) Need help and suggestions. Thanks

His springs may be a slightly light on the front. Kinda depends on total car weight, rear percentage and what shocks he is running. Posting the numbers will help if you know them

His rear % is 54 and he weighs 3020. I'm not sure what is rear shocks are but up front he has 74 and 75. I was thinking about his shocks but as violently that it throws the weight up front I figured just changing shocks wouldn't make enough difference, but I don't know. I suggested he go to 1100 and 1200 springs but then I got to thinking about his mounts on the rear and didn't know if this could possibly be causing the problem. Is it possible that going to a softer rear springs that the rebound would be less and not throw all the weight to front all at once?

Mine is 500lbs lighter and can bottom out a 1000 (rf) on a heavy or rough track. You might ask around on this one but his shocks may be 2 #'s too low as well. Easy up shocks can help retain his weight transfer front to rear.

Not sure on the rears.
