is the ball from the E4 longer (503129) longer? So I would not weaken that piviot point.
Honestly , i dont have the car in front of me yet, I will by tuesday ( i hope

) from what i ran on my older E4 i ran a 1mm shim with no problems at all, As soon as I get my car i will be testing some set ups during the week, Im planning on at least 2 days worth. I will have some set up sheets ready by sunday.
