What is the benefit of having external reservoirs on coilovers?

External reservoirs help to separate the oil and gas within the shock absorber. This allows for better heat dissipation, which means more consistent damping performance during hard driving or track use.

How do I adjust the suspension settings on these coilovers?

You can adjust the rebound, low-speed compression, and high-speed compression settings using the controls on the external reservoirs and the top mounts. There are 12 distinct positions for each adjustment to fine-tune your suspension.

Do these coilovers come with everything needed for installation?

This kit includes the coilovers, springs, and droplinks. It also comes with camber-adjustable front top mounts and solid rear top mounts. You may need standard suspension installation tools and hardware not included in this kit.

Product Details

Worn-out suspension causes poor handling and a rough ride. The AST 5300 Series Coilovers are a direct fix for BMW xDrive models. These are well-built suspension units designed for serious track use, giving you the ability to dial in your car's handling like never before. This kit includes everything needed to upgrade your suspension, including springs and droplinks.

These coilovers use a monotube design with external reservoirs. This setup handles heavy side loads and braking forces better than standard twin-tube shocks. You get separate adjustments for rebound, low-speed compression, and high-speed compression, with 12 positions for each. This lets you fine-tune how the suspension reacts to different track conditions, from smooth pavement to bumps and quick direction changes. The kit also includes camber-adjustable top mounts for the front and solid top mounts for the rear, allowing for more precise alignment adjustments.
