What is the benefit of 3-way adjustable coilovers?

3-way adjustable coilovers allow you to independently tune rebound, high-speed compression, and low-speed compression. This gives you precise control over how your suspension behaves during cornering, braking, and over bumps, which is crucial for track performance.

What does the inverted strut design do?

An inverted strut design places the larger diameter piston and seal at the bottom of the strut, with the thinner shaft extending upwards. This setup is stronger and better able to handle the significant side loads and braking forces experienced during aggressive driving and track use.

Do these coilovers come with everything needed for installation?

This kit includes the MONOTUBE coilovers with external reservoirs, and where applicable, camber-adjustable front top mounts and solid rear top mounts. It is recommended to consult the manufacturer's installation guide for any additional hardware or tools that may be required.

Product Details

Already running a dedicated track setup? This AST 5300 Series coilover kit is the next piece to take your BMW M3 or 1 Series M to the next level. These are 3-way adjustable motorsport coilovers designed for serious track use, allowing you to dial in your suspension for maximum performance and feedback. The part number is RAC-B1603SD.

The MONOTUBE design uses inverted struts to handle the heavy side loads and braking forces you'll encounter on track. Each damper has an external reservoir for the 3-way adjustment system. You can independently adjust rebound, and both high-speed and low-speed compression. This lets you fine-tune how the suspension reacts to everything from quick bumps to sustained cornering forces.
