I have a 4bar on both sides. My question is what effects side bite? I need to get more side bite in the car. Will lowing the J bar on the frame give it more or less? I am thinking that if I lower it on the frame it will lower the roll center and make the car have more side bite when the track gets slick. Is this correct or am I out in left field somewhere? Also, will lowering the R bottom bare help and if so what is the negative action of this? I don't want to lose any more forward bite than I have to either. Any help would be greatly appreciated. THANKS.

Try useing a panhard bar instead of a Jbar worked for us .

Lowering the J-bar will help. It'll add more sidebite. Also lowering the RR bottom bar will add side bite and tighten the car, and it can add more forward bite. But you will probably notice more of a difference by adjusting the J-bar.

Also like J46 said a short bar will give more sidebite than a J-bar normally, but can cause the car to be more radical.

Are you useing the long bar? At the track I run they check the lenght and it has to be 19" from center to center. Also how much rear % is to much I can get as much as 63% but I was afriad this would cause a tight in to loose in the middle. Thanks for you'r help.

I run a 19" bar. With the rear %, I run 59% full of fuel. I know some who run 62% around here and they are fast also. So I guess the best advice I can give you is try it out.

putting more angle in the j-bar will have the most noticable effect on side bite, particularly if you go lower on the pinion mount. also a stiffer rr spring will help with side bite.

Dropping one hole on the pinion to get more angle worked much better for me than raising the frame side. I usually end up with 2-3 inches of rake but have seen cars run with much more and be fast.

When you lower on the pinion do you center your rear end back up, or let it move to the left and leave it?

yes, centre the rear end whenever you make a j-bar adjustment. 1/8" makes a difference.

How much split should be between bolt on pinion & bolt on frame.
