ok finally some progress. Installed the differential, cv axle with new boot, ground control coilover, koni shocks

I only adjusted the rear coilover half way down of what I can adjust. I want it to be right at the tire. 2.93lsd with redline. Also installed 4 stainless steel line in the rear so there is 2 left for the front. Still waiting for some more stuff. modified knuckle ( w/ aluminum bushing ) to the steering rack ( 98 M3 ), RMS supercharger Stage 2 +++, rear caliper rebuild kit, A/C compressor, modified A/c lines, treehouse racing brake booster and cab. Hoping to finish next weekend and go for a drive. Wheels on there are from a 04 325ci sport package 17x8 225/45. Don't know if I want to go bigger or not. Having a problem with the ABS pulse sensor but hopefully sort it out. If not bye bye ABS. Also replace both rear wheel bearing as they were shot.
