What is the benefit of 3-way adjustable coilovers?

3-way adjustability lets you fine-tune rebound, low-speed compression, and high-speed compression independently. This allows for precise control over how your suspension reacts to different track conditions and driving inputs, improving handling and tire contact.

Do these coilovers include top mounts?

Yes, this kit includes camber-adjustable front top mounts and solid rear top mounts. The adjustable front mounts allow for more precise wheel alignment, which can improve cornering grip.

How do I adjust the suspension settings?

Adjustments are made using the external reservoirs for compression and the damper body for rebound. Each adjustment position offers distinct feedback, allowing you to dial in your suspension for optimal performance.

Product Details

Doing a track day or serious performance driving? The AST 5300 Series 3-way adjustable coilovers are built for BMW E30 3 Series cars like your 1987-1991 325is. These are not your average bolt-on shocks; they let you dial in your suspension for specific track conditions or driving styles. You get separate control over rebound, low-speed compression, and high-speed compression, all with external reservoirs to keep things cool under pressure.

The MONOTUBE design handles the stress of hard cornering and braking. You can also adjust the ride height and spring rates to get the setup just right. This kit includes camber-adjustable front top mounts and solid rear top mounts to give you more control over your front-end geometry for better grip.
