Racer 17v With 139# of weight on left rear over right rear you really do not have any wedge weight in car .The 139 comes from left an rear heavy. Your c,w. is 1290 lr to rf which is 50.27 % If you set your c.w.to 1414 it will be 55.11% your left rear will be 263# more than right rear.Now take 1414 an subtract 1281 this is 50% of your total wight an you will get 133# of wedge weight. If you take the 263# on lr.and subtract 133# then you will see the difference between lr.weight and wedge weight. With this c.w.% and stronger lr. spring you will get bite off.If it pushes work it out less X weight an stagger .

Dan, I too am fighting forward bite on dry slick tracks. I'm running 60.5% rear weight and 50.4 CW, a steel headed 355 on alcohol. Only turnning the motor 6500/6800 rpm's. I have even removed my pullrod with the 800lb spring ,and tried a liftarm with a 175lb spring . I'm driving a 97 Harris car; LR spring is 225 infront of rearend and RR 200lb behind the rearend.Liftarm is only getting 2 1/4 inches of travel, plan on going to a 150lb spring this weekend.Any and all ideas will be appreicated

V8, you dont have enough crossweight in the car to ever get it off the corners. The left rear is what you need weight on out of the corners, and with 50%, it isnt going to cut it. Just add some. Is your car tight going in at all?

Guys we are at 53.5 cross and the car now has enough fwd bite to want more than a good 406. Raise the cross as JAMMIN has suggested but adjust all four corner wt jacks so you don't upset the ride hts.
