sweet any other details?, i finally proved the suspension on mine at the last autocross and have it fairly balanced, i can tell i have stiffened it up quite a bit by the fact that i can blow through the limited slip on hard fast turns and have never done that before, there was a couple spots where i was blowing up the inside tire pulling out of the turn in 2nd gear, guess the ol m30b35 is healthy but depending on how well the paxton blower project goes on the e30 i may add one to da shark too
the set up if it matters, 81 e12 based 633 with a e28 style rear suspension, the e12 front suspension with it's 4 pot brakes works fine with a couple tweaks, bilstein sports with unknown came on it when i got it drop springs and a modified 27mm e23 front sway bar (stock e24/e12 bar is 25mm) the e28 rear set up sports e32 750il trailing arms with their bearings instead of bushings at the subframe attaching points and vented rotors, bilstein sports with e34 525 springs with one 1/2 coil chopped on the bottom perch of the shocks (ass could drop about 3/4" but i don't feel like building camber mounts for the trailing arm mounts and any lower the camber gets bad) 18mm e28 rear sway bar on custom body mounts as the e12 runs the bar forward to the subframe and has no body mounts, a 3.73 posi diff with a old 533 center mount rear cover lines up with the e12 body mount, 16x8" msw's round things out
