How do I adjust the low-speed and high-speed compression settings?

The external reservoirs have separate adjustment knobs for low-speed and high-speed compression. You can turn these knobs to change how the suspension reacts to different types of impacts. Refer to the AST manual for specific adjustment ranges and recommendations.

What is the benefit of an inverted strut design?

An inverted strut design places the larger diameter piston rod at the bottom and the larger cylinder at the top. This setup is stronger and better able to handle the significant side loads and braking forces that occur during hard cornering and braking on a race track.

Do these coilovers come with everything needed for installation?

This kit includes the MONOTUBE coilovers, external reservoirs, and 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 for proper installation.

Product Details

Worn-out suspension components cause poor handling and reduced control. The AST 5300 Comp Series Coilovers (Part# RAC-B1405SD) are a direct fix for your 2021 Mini Cooper F56 GP3, offering advanced adjustability for serious track use.

These are MONOTUBE coilovers with external reservoirs. They let you dial in rebound, low-speed compression, and high-speed compression separately. This means you can fine-tune how the suspension returns after a bump, how it reacts to slow body movements like leaning in a corner, and how it handles sharp impacts. The inverted strut design handles heavy side loads and braking forces common on a race track. You also get adjustable front top mounts for camber changes, which lets you alter front-end grip.
