What is the benefit of 3-way adjustable coilovers with external reservoirs?

3-way adjustability allows you to independently control rebound, low-speed compression, and high-speed compression. External reservoirs make these adjustments easily accessible, enabling fine-tuning for specific track conditions and driving styles.

How do the camber-adjustable top mounts affect my car's handling?

Camber-adjustable top mounts allow you to alter the front-end geometry of your vehicle. This adjustment can improve front-end grip and cornering performance by optimizing tire contact with the road during turns.

What is the difference between low-speed and high-speed compression adjustment?

Low-speed compression controls how the suspension reacts to gradual forces, like body roll during cornering. High-speed compression manages how the suspension handles rapid impacts, such as hitting bumps or curbs at speed.

About this part

Product Details

For dedicated track use, the AST 5300 Comp Series Coilovers are built to help you push your 2015-2019 BMW 1 Series (F20/F21) or 2 Series (F22 LCI) to its limits. These aren't just about lowering your car; they offer a sophisticated level of tuning that lets you dial in your suspension for specific track conditions and driving styles. The core of this system is its 3-way adjustability, allowing separate control over rebound, low-speed compression, and high-speed compression, all managed through external reservoirs.

The MONOTUBE design in both the front and rear dampers is chosen for its ability to handle the significant side loads and braking forces encountered during aggressive driving. You can independently adjust the return rate of the dampers (rebound) across 12 distinct positions, and separately control how the suspension compresses under gentle (low-speed) and rapid (high-speed) impacts. This level of control allows you to reduce body roll in corners, improve steering response, and ensure your tires maintain consistent contact with the track for maximum traction. The kit also includes camber-adjustable front top mounts and solid rear top mounts, giving you further ability to alter front-end geometry for improved grip.

With this setup, you gain the flexibility to fine-tune critical suspension characteristics. Balancing rebound and compression settings can transform how your car handles, making it more responsive and stable. You can also adjust these settings to find a balance that suits your comfort preferences while still maintaining track-ready performance. This is a comprehensive system designed for serious track enthusiasts looking to extract the most from their BMW.
