What can we do to stop the body from rolling over so far on the right. Preferably without changing the percentages too much?

Springs and/or sway bar diameter/preload are what ulitmately determine how far it's gonna roll. The only 2 choices are 1.) cut weight and 2.) raise spring rate or get a bigger sway bar.

Would we need to raise the spring rate in the front, rear, or both?

raising the right front spring or tightening the sway bar will make the biggest difference.

Can you tell which end is rolling to far? Does it pitch on it's nose in the corner?

where is your weight mounted? The further from the center of gravity the more it will counter itself once it gets loaded up with energy.

Just another suggestion.

I'm having the same problem, mine is so bad that the tie-rod is rubbing the frame last week we put new stock springs on. we have to run the same stock springs on both sides. They check by counting the number of coils and measuring the diamiater of the coils. I had taken the front sway bar off put it back on today do you think it will help. I'll posts the results after the race tonight.

Hobby, could you run a spring rubber? It would increase the spring rate but allow the springs to be the same. Just a thought.

That's a good idea and our rules don't say anything about spring rubbers they only say no heating bending or cutting and they must match. I'll keep that in mind i put the sway bar back on and the car handled much better till i got spun and T-boned so i'm going to leave it and see how it is before doing anything else.

I was just reminded that the rules on our track web site our not the most up to date the rules do say no spring rubbers or spacers any other ideas if the sway bar dosen't work.

A sway bar will make a big difference. Run a stock, or decent height spacer, on the right side, and a 1/2" bolt with about 1/2" of play on the left side (no spacer at all). On dry slick, crank the bolt down on the left side to add cross.

A 1" bar will make about a 100 lb change to the right front spring in the turns. A 1 1/4" bar will make about a 200 lb addition to the right front spring in the turn.
