Launch Questions
I think with this years motor changes I am making more power at the launch and overpowering / hitting the tires too hard. To get the car to work last year the Torque Arm is set in the top hole (all the way up) and the LCA's are set in the lowest hole (all the way down) on the rear end brackets. The front shocks have been set on 0/0, 1/1 and 2/2 while testing. Which on 0/0 should have the suspension set up to hit the tires as hard as it can.
I'm thinking that I need to adjust the IC to soften the hit since I think I'm overpowering the tires. I would do this by moving the LCA's up? The T/A down? Both? Or should I stiffen the front shocks up more?
Looking for any input or suggestions...
