I have had QA1's on my 95 Z for a while now & cannot get a better 60' than without them. Previously had consistent 1.85-1.90 with a best of 1.78 with LCA's only & 275/17 Nitto DR's. Then I added: 1.adj torque arm set to -2 2. BMR front A-arms 3. QA1 shocks front & rear with stock springs in back & QA1's in front 4. BMR Adj PHR. Most of my track time I have had the fronts at either 1 or 2 & the rears from 6-12. My best 60' with this set up is high 1.8's with consistent 1.95-2.0's. I also tried some 15" BFG DR's with the same result. Car has built A4, 3.23 gears & vig converter 3200. Ran 12.30's before susp change. Any suggestions will be appreciated. I really do not want to run slicks or ET streets.

 

TTT. Any suggestions?

 

Do you have anything to prevent body roll on launch... e.g. an airbag or a stiffer rear sway bar? Have you verified the measurment on the pinion angle?

Each car is different, but I've found the QA1 fronts will generally be in the range of 0 to 2 clicks from full soft, and the rears in the range of 4 to 6 clicks from full soft.

 

I have checked & doubled checked pinion angle after checking out every website to make sure I am doing it correctly (still only 90% sure it is correct). Stock sway bar & no airbag. I forgot to mention I do have weld in SFC's. Witness says that car squats evenly on launch.
