Traction problems

[bOb shingler]

the other guys have some great suggestions for you to try. you just can't go wrong reading the chassis manual. you can lower the back by raising the front spring eye up. have you ever tried taking off at idle speed? this doesn't use up any of the suspension travel.

Your rear is unloading after initial launch and spins the tire, then grabs again.
This is what I would do with the parts you have.
Front shocks set to 90/10 Trim the upper control arm bump stops to allow more downward travel.
Rear shocks set to 70/30. You want the shock to extend easy to plant the tires. Firm rebound keeps them planted.
If your snubber is adjustable set it to within a 1/4" to 1/8" with driver in seat race trim.
Lowering blocks would also help weight transfer.

I run 255/60/15 MT drag radial 18 psi, small burnout just to clean.

Here's a video of my car. At :25 the car is stage and on the snubber. At ;28 the tires are planted and stay that way.

Yup. This here ^^^^^^ is good advice. I like your car too. Badassary.

What is the spring rate for the SS you are running. They look too stiff.
