This is our 1-piece Carbon Fibre conversion for the BMW E46 (6-Speed Manual Transmission ONLY, will not fit SMG). The shaft is made from 2.75" x .170" tube with a 108mm CV to mount to the differential, which will eliminate any possible pinion angle issues. This shaft weighs 20lbs and since we are removing the hanger bearing, it will make the car seem more athletic and give it a smoother power transfer. This shaft is now being balanced on our new 9500RPM balancer to ensure a perfectly balanced shaft. Comes complete with adapter plates to mount up to the transmission and differential flanges and all necessary hardware for installation.
