What is the benefit of 3-way adjustable coilovers?

3-way adjustable coilovers allow you to independently tune rebound, low-speed compression, and high-speed compression. This level of control lets you fine-tune your suspension for specific track conditions, tire choices, and driving styles, improving handling and responsiveness.

How do the external reservoirs help?

The external reservoirs increase the oil capacity within the shock absorber. This helps to dissipate heat more effectively, preventing shock fade during prolonged hard use like track driving and ensuring consistent damping performance.

What is the purpose of camber-adjustable top mounts?

Adjustable top mounts allow you to change the camber angle of your front wheels. This is crucial for optimizing tire contact with the road during cornering, which can significantly improve grip and handling performance on a track.

Product Details

Doing a track day or serious performance driving? The AST 5300 Series Coilovers (Part# RAC-B1101SD) are built for dedicated BMW E46 3 Series owners looking to fine-tune their suspension. These aren't your average bolt-ons; they offer independent control over rebound and both high and low-speed compression, giving you the ability to dial in your car's handling for specific track conditions.

These coilovers use a MONOTUBE design for consistent damping and feature external reservoirs for increased oil capacity and better heat management. The inverted strut design handles the heavy side loads and braking forces common in performance driving. You also get adjustable front top mounts with camber adjustment to fine-tune front-end grip, and solid rear top mounts.
