What does 3-way adjustability mean for my car's handling?

3-way adjustability means you can independently control rebound, low-speed compression, and high-speed compression. This allows you to fine-tune how your suspension reacts to different types of bumps and cornering forces, giving you more control over grip and stability.

Do these coilovers come with everything needed for installation?

This kit includes the MONOTUBE coilovers, external reservoirs, camber-adjustable front top mounts, and solid rear top mounts. You will need to refer to the manufacturer's installation instructions for any additional hardware or tools required.

How do the external reservoirs help?

External reservoirs help to separate the oil and gas within the damper. This design helps to keep the damping fluid cooler under heavy use, which prevents overheating and maintains consistent damping performance during track driving or spirited runs.

Product Details

Doing a track day or serious road course driving in your 1988-1991 BMW M3? The AST 5300 Series coilovers are built for that. These are 3-way adjustable dampers, meaning you can independently control rebound, low-speed compression, and high-speed compression. This lets you dial in the suspension exactly how you need it for grip and handling.

The MONOTUBE design handles the stress of hard driving. You get external reservoirs to help keep the fluid cool and consistent. Plus, they include camber-adjustable front top mounts and solid rear top mounts to give you more options for setting up your front end geometry. You can also adjust the spring rates and ride height to get the setup just right.
