i was reviewing tape of tues. nights race last night and it became apparent that i need more sidebite and forword bite on my 4-z dw8 mod.
550 / 650 front 200 on coilover on bc behind lr 4 link . short lower 5* up longer upper
18* up
rr z link 20" long 5* up to front lower top level 20" long to rear with 170 on coilover on front of bc

4" offset both left side tires, 3" offset both right side wheels with 1" front stagger and 2.5" rear stagger

tire pressures 8.5 lr, 10.5lf, 12.5 rf 12rr

looking for more forword bite and more side bite in the corners, car is fast but get wheel spin upon re accelaration in corner
j bar 1" below pinion center / 6" higher on frame
54 left , 58 rear, 50 cross, 80lb lr bite

This is what i would do, your mileage may vary.

You running any split valve shocks? if its really slick 7/2 LR, and 2/7 RR, with a 6/2 on the RF and 5/3 on LF will help (compression/rebound)

Switch the rims, 3" on RF, 4" on LF, 4" on RR, 3" on LR.

You should find that it ends up with more LR bite, and it may steer in well enough that you wont have to let all the way off in the corners. Thats always a good gauge for me if a car is fast / faster.

More LR bar angle, 25* or so. More in the bottom as well, 10* or so. Dont be afraid to run some major bar angles but watch the overcentering of the BC problem.

More LR bite, 100Lbs. The wheel offsets may take care of this.

How is the car running now? after you got it all figured out from the bad spring ordeal? If its driving good, use what you got for a good base set up and write it down. Then start tweakin from there.

hey krom, good to hear from you again,
if you ever need it ...my e mail is ron.paulick@hydrite.com

anyhow..the car is working really well but could be better, in the heat tues we came in 5th...we had a 3rd sewn up and the steering box went south at the checker and i slowed to correct it (it looks on tape like the box didnt catch then went all turned all at once so i had to slow and ended up 5th)
ended up 5th.

in the b we needed 2nd place to transfer out of 16 cars , ended up 8th and cut a tires on a loose car trying to pass him. luck ???

so now i am looking for more corner speed and less corner slow down.

i will try some of this, also still only have 15* on my pullbar and 5* on my 10-90
with a 600-1200 progressive pullbar spring

Yep your on the right track i think, less corner slow down, more speed.

Pull bar angle looks good, you could put more angle in it to get some instant bite maybe but that may or may not work.
