What is the benefit of having external reservoirs on these coilovers?

External reservoirs help to keep the damper fluid cooler under extreme use, which can prevent shock fade. They also provide easier access to adjust the damping settings without removing the suspension components.

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

The camber-adjustable top mounts allow you to precisely adjust the wheel's camber angle. This adjustment is crucial for optimizing tire contact with the road during cornering, which can significantly improve front-end grip and steering response on the track.

Can I adjust the spring rates with this kit?

Yes, the manufacturer states that you have the flexibility to adjust spring rates on these dampers, allowing you to further tune the suspension to your specific needs and driving style.

About this part

Product Details

If you're serious about hitting the track and want to fine-tune every aspect of your 2011-2015 BMW 1 Series (F20/F21) or 2 Series (F22 PRE LCI) suspension, these AST 5300 Comp Series coilovers are built for that purpose. They allow for independent adjustment of rebound, low-speed compression, and high-speed compression, giving you granular control over how your car handles under extreme conditions. The inverted strut design is a solid choice for managing the significant side loads and braking forces encountered during track driving.

Each corner features a monotube coilover design with external reservoirs. This setup provides 12 distinct positions for rebound adjustment, controlling how quickly the damper returns after compression. You also get separate adjustments for low-speed and high-speed compression. Low-speed compression affects how the suspension reacts to gradual inputs, while high-speed compression handles rapid impacts. By balancing these settings, you can reduce body roll during hard cornering, improve steering response, and keep your tires firmly planted for maximum traction. The kit also includes camber-adjustable front top mounts and solid rear top mounts, allowing you to dial in front-end geometry for enhanced grip.

With these coilovers, you can adjust ride height and customize spring rates to match your specific track needs. This level of adjustability means you can fine-tune the suspension for a unique driving sensation and optimize performance for various track conditions.
