I just saw your other post about fast wear on the slicks.
First: Pitt is very hard on the driver front (rotate side to side helps)
Second: go with a wider tire on that rim. It will give you more center contact area
Third: I would not add more camber than 3 degree's at pitt, I bet the inside of your Passenger tire was very close to cords also.
40-42 psi hot is perfect for the weight of our cars on R7s. You need to reduce push to fix your edge wear... Wider front tires is a start. Also consider less rear camber. Run your front toe and rear toe at 0.
I hope this helps. Don't go spending 8k on suspension trust me what you have is great! Work on getting the handling balanced first. then look in too a dsc controller.
