What is the benefit of 2-way adjustable coilovers?

2-way adjustable coilovers allow you to independently tune both the compression and rebound damping. This means you can fine-tune how the suspension reacts to bumps and cornering forces, offering a much more precise setup for track or street driving.

What do the external reservoirs do?

External reservoirs hold extra oil for the dampers, which helps with cooling and allows for more consistent damping performance, especially under heavy use like track driving. They also house the adjustment knobs for compression and rebound.

What is the purpose of camber-adjustable top mounts?

Camber-adjustable top mounts allow you to change the angle of the top of the wheel relative to the vehicle. This adjustment is crucial for optimizing tire contact with the road during cornering, which can significantly improve front-end grip and handling.

About this part

Product Details

AST is known for building serious performance suspension systems, and their 5200 Series Coilovers are a prime example. If you're looking to take your 2012-2015 BMW M3 (F80) or M4 (F82) Pre LCI to the next level, especially for track use, this kit is designed to help you get there. These aren't just about lowering your car; they offer a deep level of adjustability to truly dial in your suspension's behavior.

What sets these coilovers apart is the 2-way adjustability, meaning you can independently tune both the compression and rebound damping. This is handled through external reservoirs, giving you distinct control over how the suspension compresses and returns. With 12 distinct positions for each adjustment, you can fine-tune the car's response, manage body roll in corners, and maintain tire contact for better traction. The inverted strut design is built to handle the significant side loads and braking forces common in performance driving. You also get the flexibility to adjust spring rates, and the kit includes camber-adjustable front top mounts and solid rear top mounts to further refine your alignment and front-end grip.

This set includes everything you need to get started, including the springs. The ability to precisely adjust both compression and rebound allows you to not only optimize performance on the track but also find a more comfortable balance for spirited street driving. It's a comprehensive package for drivers who want to experience their BMW's full potential.
