Ok what all do you have for rear suspension? Aftermarket Torque Arm? LCAs? Panhard rod? you say 3 degrees negative? you mean for your pinion angle? what RPM's are you leaving at? off a transbrake? without knowing that stuff, I'd say: try 18#'s make sure pinion angle isn't anymore than -2 degrees launch higher a lot of times you get tire shake because you are actually not hitting them with enough power Dave Brown www.wheelsupracing.com |

Crank the shocks all the way tight. Stick the torque arm in the bottom hole. I would run about 15 lbs in the tires. Been a 1.36 on the old BFG's and been high 8's in the 1/4. Building a new radial car now. Should go high 7's with it  . Good luck. |

I dont have an adjustabe front on the torque arm just at the rear lower control arm mounting point,right now they are 2 ins below the factory mounting location and I can go three total.Will that help,also when I was at the track last nite I had the shocks at full stiff and pressure at 14 cold and it immediately blew the tires off...So I loosened the shocks and it tire shook real hard...Thanks for the replies,,Roger

No good results yet..I found I had a bad QA1 rear shock,its brand new and its bad...LOL And I also took the 325s off and put on 295s cause I only have an 8in rear rim on the car...Im gonna try a wilson two stage plate also,a friend has one for me to borrow and if I like it Ill buy it..I am going to goto bradenton on Sat then down to Immokalee for a stock suspension race..Hopefully all goes well and Ill see some low 6s to high 5s in the eighth...Lata,Roger

The 8" rims were killing ya with the 325's. Throw in a 10" and see how much better it is. you'll be amazed.

Heres an update....Went to Immakolee for a stock susp shootout.went 6.40 at 115.6 ..Best 60ft was a 1.55 .I looked at a few fast 3rd gens and they all seemed to have the front torque arm mount lower than mine..My torque arm is pointed upward about 3 to 5 degrees and theres was paralell if not down a lil.. I still had a lil of the tire shake issue still..But all in all I was happy,I made it to the semis out of 16 cars I qualified #12 fastest was a 5.30 So I had a good nite....Any Ideas on the torquae arm????Thanks Roger |
