I run the rear hangers flat, no shims. I tried running shims but wasnt a fan of the high rollcenter. Car comes around too much on exit and it never felt consistent exiting on our low-med/med tracks. Thats for the rear, I do like .5 shims in the front of the car to take away a little nervousness.
I have a low-med/Med setup if anyone cares to try it, its allot different from what the norm is but curious if someone will try it on lower bite tracks.
Would be interested in seeing it.
