For Sale Forged Wheel Drive Hub and Sprocket. Will only fit HP4 Forged wheels or 15/16 with Forged Wheel option. Does not wobble when in the wheel for sure on my wheels. Scratches are from the chain upon changing out rear wheels in too big a hurry at track days and BEFORE I got my LighTechs. The LighTechs are awesome. The next improvement to rear wheel changes was the underslung Brembo caliper assembly. Stock sprocket ( 45T ) on the drive hub. Sprocket has about 5K miles or really less. I have 4 rear forged wheels and this was just a spare I cycled in a few times. Just getting rid of a few S1KRR parts before winter. $175 shipped to all 50 states ( Flat Rate Priority Mail with Tracking ) $200 shipped to Canada ( could be cheaper upon checking the exact rate via USPS with your address ) $225 shipped to AU or UK ( could be cheaper upon checking the exact rate via USPS with your address ) This item as is offered would be $659.27 from a BMW dealer 33 81 8 532 733 FIT BOLT - M12X1,5 0.11 5 $30.25 33 81 8 530 679 SPROCKET HUB 1.17 1 $501.85 33 81 8 532 146 SPROCKET - Z=45 2.23 1 $106.32 27 71 7 724 142 FLANGE NUT 0.04 5 $20.85
