I ended up replacing Diff bushings for stiffer ones, since the diff was going to be replaced anyways, might as well upgrade that, but it's not necessary.
Ah, I see. I'm at 102K miles, and I have a bolted diff, so its a much simpler install. Was just wondering if I would need these other parts:
E90 335I: FBO +wavetrac LSD
E92 M3: K&N, Rouge Engineering Pulleys, Macht Schnell Test Pipes-w/ebay rear O2 spacers, Pagid S, V1
