60 Foot help needed
Hi guys,
Need some of your wisdom on setup for launching this thing. 70 GTO stock body 3950 race weight. ~550HP, TKO 600, 4.10 rear, RXT Mcleod dual disc clutch Adjustable uppers/lowers, no hop bars DMR BMR anti roll bar, -2.5 pinion angle 8" rims stock width 12 bolt, fenders, etc. MT ET Street R 28x11.50-15 Bias with tubes. although the below pic and a couple outings i have made it hook, it is 1 out of 10 launches. Mostly spinning the tires. Tried all over the place on air pressure, shock adjustments, etc. spoke to suspension guy, says to look at my tires. had to go almost all the way stiff on compression to get rid of hop. speaking to Hoosier they recommended their Slick non DOT 29x9-15 with D07 compound for stick cars. The tread width on these is actually more than i have with the MTs. I dont need DOT rating. Video 12psi 4500 launch tires smashed all the way down. still spin https://youtu.be/nBpIAicgp54 next one 14 psi 4000 launch more spin https://youtu.be/3NzubSEvb3o more details on shocks in video description. Thanks in advance
