When S2000 ride height is lowered, the angle of the driveshaft with respect to the hub changes and slightly pulls out the driveshaft. Driveshaft spacers help prevent premature bearing and CV joint wear. CNC machined out of 6061 aluminum, using 10.9 high grade 14mm flange bolts. Spacer thickness is 10mm. To ensure balance this spacer was constructed out of a single piece design versus competitor two piece design. This lowers any rate of failure and loss of spacers reported by owners who traded over from competitor 2 piece brands over to our single construction.
