I realized I had a bit of a problem in that the rear wheels could not be installed/removed without dropping out the entire rear end. Reason being is the rotors proximity to the skirted rear fender. Nothing would fit between it.
The more I thought about this the more it bothered me so I knew it had to be fixed.
Solution was upgrading to a GMR floater and moving the brakes as far inboard as possible. Also had to rotate caliper position so the top of the caliper was no higher than the top of the hub. This now gives me almost 11 inches between the rotor and the fender to install the 20x9 wheel and 255/45/20 PSS.
Decided on 6-piston PBR calipers (C6Z) and Wilwood rotors.
Donny at Frame-Up Wheel Works (dontlifttoshift) tackled this project for me and he was great to work with. Every aspect of his work, from track width, caliper position and modifications required to get the rotors to work with the calipers was absolutely spot on perfect. Thanks Donny!!!
I had already built a 31 spline true-trac setup so I had to sell all that and put together a new one. Ended up with a strange iron housing, 35 spline S-trac and oem 3.50 gear.
Should work out nicely!!
