How do I adjust the rebound and compression settings?

The AST 5200 Series coilovers feature external reservoirs. You can adjust the rebound and compression damping by turning the knobs located on these reservoirs. Each adjustment position provides a distinct change in damping force.

What is the benefit of the inverted strut design?

An inverted strut design places the larger piston and damper rod at the bottom. This setup is stronger and better able to handle the significant side loads and braking forces encountered during performance driving and track use.

Do I need to buy separate top mounts for installation?

No, this kit includes camber-adjustable top mounts for the front and solid top mounts for the rear. These are designed to work with the coilovers and allow for alignment adjustments.

Product Details

Doing a track day or pushing your BMW M3 to its limits? The AST 5200 Series coilovers (Part# RIV-B2112SD) are built for drivers who want serious suspension performance. These are designed to handle the demands of track use, letting you fine-tune your car's handling for better grip and control.

This kit uses a monotube design for consistent damping. The inverted strut design handles the side loads and braking forces you get when driving hard. You can adjust both the rebound (how fast the shock returns) and compression (how fast it compresses) independently using the external reservoirs. This lets you dial in the suspension for different tracks or driving styles.
