1" is from the back of the rim to the rim center may be back space that im thinking of. other cars in my class like the top runners r running any where from 750 to 1000 on the outside front with the same weight cars. last year the car was rollin gover on the rf way to much it was pushing the sway bar links through the rubbers this year it is not rolling over and it seems to be stiff enough but i cant get the rear to come around i have 100# in the trunk on the left side.it seemed to help keep the lr tire on the track it was lifting off last year. maybe with the new spring up front i will not need that weight in the rear to hold the tire down waht do u think?

I'd start with removing the 100lb off the Lb.Does your track dry out if so that may be the only thing you need to do for now. Dry track you may need it. Some low bank tracks run the bigger springs on the Lf. Good Luck.

Well stagger in the rear will help i would say start at like a 2" roll out difference in the rear with 4" offsets on the rear. Narrow rearend will help car come around better. Also that weight on the left rear might need to come to center you need to post weight % and tire preasure for these guys to help you correctly. Go to 1100 atleast up front on the rf

try simple first move that 4" to the rf and 2" to the lf if you are using a large amount of stagger on the front swap tires on the wheels.

I had a similar problem with the soft springs in the front and a heavy car. Not sure if it is your problem but something to check. When your car rolls over in the turn and compresses the spring enough to botom out the control arm on the frame (hopefuly you removed the stock bump stops) it increses the spring rate infently witch will cause the push in and off until the the suspension rebounds and you start using the spring/shock again. I set my shocks up to botom out 1.5" after the lower control arm makes contact with the frame

ok hey r the air #'s 9lf 12rf 11lr 14rr last year i was running a 700 on both front springs and the cornered good but would roll over way too much and it would pick the lr tire off the race track so i tryed the 900 rf and adding weight to the lr now it is totally wacked. on the front the stager has always been really close to even. the rear i run a 2" stager but i have never ran that rim on the rear before. im going to take it off and put a rim that will **** it more under the car and the weight is coming out i can run 3200# so it will drop my over all as well. as to JYD97 the track stay tacky for the most part but it does dry out when we have the sprint cars there but thats only 4 nights a year

Remove the sway bar and you can probably remove the 100# of lead. The sway bar is not allowing the chassis to roll over on the right rear. Sway bars are for asphalt, not dirt. Throw the dang thing away and you'll be much happier.
