T-Works MTC2 wheel hub axle set
T-Works have produced this wheel hub axle set for the Mugen MTC2. Mounted over the kit standard wheel axle, the bearings used in the wheel hub have a larger internal diameter to accept the hub axles. The system improves traction and rotational efficiency by transferring the loads from the wheel directly to the bearings. The set includes a pair of hub axles, as well as 6x10x3mm bearings, spacers, shims and pins.
