How do I adjust the compression and rebound settings?

The compression and rebound adjustments are made via controls on the external reservoirs. Each adjustment position provides distinct feedback, allowing you to fine-tune the suspension to your driving needs.

What is the benefit of the inverted strut design?

The inverted strut design places the larger diameter piston rod at the bottom. This setup is engineered to handle the significant side loads and braking forces encountered during performance driving, improving durability and performance.

Do these coilovers come with everything needed for installation?

This kit includes the monotube coilovers, springs, external reservoirs, and camber-adjustable front top mounts with solid rear top mounts. Refer to the manufacturer's installation instructions for any additional hardware or tools that may be required.

Product Details

AST makes these 5200 Series coilovers for the 2001-2006 BMW M3. If you're serious about track performance and want to dial in your suspension, these are built for that. They let you adjust both how fast the suspension compresses and how fast it returns, using external reservoirs to hold more fluid and keep things cool under hard use.

These are monotube coilovers, meaning the damping is handled in a single tube. The inverted strut design helps them handle the side loads and braking forces you get when pushing the car hard. You can also adjust the spring rates if needed. The kit includes top mounts with adjustable front camber to help you fine-tune your front-end grip.
