I can't get a step-up down on my pro 4. Everytime I get on the gas it just spins out. It is so bad I can't do a clean lap without spinning out. My spring in the rear AE silver. Shocks are at second inner most positon. Roll centers are stock. Chamber angle has a 2mm spacer under the ball joint. I am almost ready to sell the car. So please soon. Thanks for any help you can give.
