Update! My old trailing arms were cracking pretty bad at the differential so I ordered new ones from cpp. Put them on and moved the trailing arms up considerably. I had a 6 point rollbar welded in the truck also. I went back to the track and took the hoosier slicks in favor of the 315/60 et street radials. Make one solid hit on motor. Quickest and fastest the trucks been on motor. And then sprayed it but spun first attempt. So I progressed it out .6 with a slow ramp. It sounds like it still spun on the video but 60 foot was decent and went quicker and faster than ever. Density altitude was negative this night. But it was dewing really hard
