Product Description
ST XA coilovers are for the E92 owner who wants more control than a fixed lowering spring setup can provide. You can set the ride height to suit the wheel and tire setup, then use the rebound adjustment to make the car feel more comfortable for normal driving or firmer for more aggressive use.
The dampers use 16 rebound settings, adjusted at the top of the piston rod. The kit arrives at ST's recommended baseline setting, so you have a known starting point rather than needing to guess from the first drive. From there, make small equal adjustments side to side and take time to feel the difference before going further.

Before You Buy
Plan on a professional alignment after installation and again after any meaningful ride-height change. Keep the car within ST's tested adjustment range, and do not use spring preload just to make the car sit lower. Confirm your exact body style and drivetrain before ordering, since this page is for RWD E92 coupes only.
