    Can some of you chassis/suspension tuning experts take a look at my vids & see if you have any advice for me?? It's a 85 camaro with ladder bars (fronts are down 3 degrees), qa1 double adjustable coilovers (don't remember exactly how many clicks but I know the extension is one click tighter on the driver side & the compression is one click tighter on the passenger side & I have a little preload in the spring in the passenger side. I THINK the driver side is 5 & 6 and the passenger side is 6 & 5), koni adjustable front struts with coilovers, set on 1 turn from full tight, limiters that are only limiting enough to keep the spring in place, 28x10.5 M/T ET drags & 3100lb race weight. Never had the car scaled so don't know the corner or front/back weights but it is nose heavy with the 572 in it. The video pass is on a 200 shot. It's been 5.94 @ 118 on motor with a 1.31 60' but this is the best nitrous pass so far (only 3 total) & only went 5.74 @ 124 w. 1.30 60' (went 126mph on the previous pass).

    here's the burnout vid. Looks to me like the passenger side tire isn't getting hot enough which I wonder is why it drove to the right so hard.





    Here's the pass......




    Thanks for any advice guys.

    That's what I'll do. If that doesn't work I'm gonna get the longer springs from Spohn. Will they work if I just buy the springs & not the complete coilover kit? Springs should be the same diameter right?
