I decided to try something different last night on a southern sport mod (stock metric full frame, 2500lbs).

54% Cross & 155lbs Bite. On a drying track - let off and it got way loose, pushed somewhat under throttle. Car had too much left rear.

What is the max cross/bite you guys can get away with?

I've never been able to go much more than 47-48%. But then, ever car is a little different. Some of my friends run 49-50% and do good; but I don't know any that run that much cross(not saying that some drivers don't).

How much left rear did you have in the car. Cross ##'s are great but I think most people look at the amount of left rear in a car. Because if you have a car with not much left in it you could have alot of cross and still not have much left rear in the car. How much rear do you have? We have run 55% cross before. Depends on your springs as too how much left rear bite your car can take. We have ran anywhere from 40# tp 250# of bite. If you run alot of bite you may need to run a stiffer right rear spring to keep the car from getting loose going in. And it will also keep it from pushing on turn exit. (Stiffer right rear gets you tighter in looser off and the oposite is true). Good Luck.

Cross means so little in these cars, its not even worth worrying about. Set your ride heights and put a lil bite in it, guys read way to much into stocks.

Bite is the diference in the weight of l.r. and r.r. is the pounds of bite.l.r. needs to be higher than the r.r.

Our car runs 57% cross. Our track goes dry slick. so, In heats car is tight, we put rear stagger in it, handles great. For feature we take out the stagger and car is fantastic around the bottom. Just a tick loose up top.

Before this season, I only had 49% rear and I could never run over 50% cross. It would just not turn with that much cross. This year I put the car on a serious diet and got my rear up quite a bit. Now I run 51% to 52%, so I really think the amount of cross is very dependent on rear % on a metric car. I know mine is.

ufna , I agree with your assessment. Our car has 52.5rear/51.3cross and 53.5 left. We drop some cross during the main but only about.25%. one of the biggest faults I see
other drivers make is to overdrive the cars during the main when its gets dry and then blame it on the set up
