Description
The AST 5300 Comp Series Coilovers for the 2015-2019 BMW 1 Series F20/F21 and 2 Series F22 LCI are designed for motorsport enthusiasts seeking precise suspension control and enhanced performance on the race track. This 3-Way Adjustable suspension system offers complete control over your car's handling and ride dynamics, enabling you to adjust rebound and low- and high-speed compression independently, giving you the ability to fine-tune the vehicle’s behavior to match track or road conditions.
The coilover system features an inverted strut design that can handle significant side loads and heavy braking forces, ensuring stability under extreme driving conditions. Both front and rear dampers come with MONOTUBE construction, delivering improved durability, heat dissipation, and consistent performance over extended use.
One of the key benefits of the AST 5300 series is the ability to adjust spring rates and fine-tune rebound and compression settings. You can control 12 rebound adjustment positions, which dictate how the dampers extend back after compression. This allows for a tailored driving experience with distinct feedback at every position.
In addition, the suspension allows for separate low- and high-speed compression adjustments. Low-speed compression refers to how the suspension reacts to gentle, progressive forces, while high-speed compression helps handle sudden impacts and rapid suspension compression caused by road irregularities or aggressive track driving. By fine-tuning both settings, you can reduce body roll during hard cornering and improve responsiveness without sacrificing ride comfort.
The set includes camber-adjustable front Top Mounts and solid rear Top Mounts, allowing you to adjust the front-end camber to optimize grip and cornering performance.
