Slammed S2k can have premature axle life span. Check out the video to see why. Below is manufacturer specs from their website.
When lowering a S2000 , its driveshaft angle will definitely need re-adjustments due to the modifications applied, in this case, the lowering of the suspension. This is due to the fact that lowering a S2000 creates unwanted space in between the driveshaft roller and spider (inside of the driveshaft), causing the inboard joint to unevenly wear out. With the installation of T1R Half shaft spacers, it will prevent the driveshaft from losing its regular position and it is highly recommended for any lowered S2000.
