Caltrac Tuning Info LOOK HERE

@pettybluedart.Your car looks good. Mine was launching, then going out about 30' and spinning.If you bolted the rear shocks on stock, look to see how much travel you have. Mine only had 1/2", so they bottomed out.I made some shock extensions to lower them about 4". It made all the difference in the world.
I also went to #3 on setting, and no preload. Just adjusted snug (1/32" clearance). The only issue I have is slight inconsistant spin at the hit of the launch.I am running 12 LBS air. I am going to add preload, and more air.
I leave @ 5000 RPM
