4 pin design to ensure the hub won't spin, even with heavily modified S55s. Laser scanned to ensure perfect fitment – direct replacement for stock. Designed and machined in-house on our HAAS 4-axis CNC mill. Machined from heat-treated 4130 Chromoly. Drill bits are included in the kit.
New crank bolt is required from BMW, not supplied in the kit.
Been tested on Viper, as seen in the video below ,a 750bhp F80 M3 for over a year with 50+ Dragy runs and 2 VMAX events, the clutch slipped before the crank bub did!
Please Note: Installation is available at our partner garages in Stockport and Luton. Please contact us for bookings and availability.
