I have a 2010 E89 3.0si 6 speed with 10K on the odometer. Several people on this thread have noted there is no replacement for the E89 rear lower control arm bushing at the hub. The E89 upper control arm has the same bearing as the E46 M3. The E46 M3 uses this same bearing at the lower control arm. I did some home work. First off, Super Pro offer a polyurethane bushing kit for this application P/N SPF3806K. I ordered the kit and its a nice piece. I still preferred the M3 bearing so I ordered a stock E89 bushing and a pair of M3 bearings. The M3 bearing is .16mm (.0063") smaller in diameter than the E89 bushing. The bearing and bushing is a press fit into the hub. To make up the slight difference in diameter between the two parts I applied a small amount of Loctite 641 bearing retainer on the M3 bearings when I pressed them in. Loctite 641 can accomodate up to .008" diametral clearence. It also allows the bearing to be pressed out if required. As the bearing only sees radial load this should not be a problem. See attached photos. I now have a complete M3 suspension on my E89. E90 M3 tension struts and control arms at the front and E46 M3 RTAB's with Vorschlag limiters and E46 upper and lower M3 hub control arm bearings at the rear. I also added H&R sway bars with rod end links at the rear and Koni FSD shocks all around. I'm running TSW rotary forged 18x8.5 Fr and 18x9.5 Rr rims shod with 235/40 Fr and 265/35 Rr Firestone Indy 500 tires (rebadged Bridgestone R003's). I kept the stock springs and ride height. I installed Ground Control camber plates and a Turner strut bar up front. I also added 330 Front brakes, slotted rotors all around and Cool Carbon pads. I now have a car that handles great at the track or autocross but is still comfortable to drive on the street.
