What is the benefit of having external reservoirs?

External reservoirs help keep the damper fluid cooler under extreme conditions, which prevents "shock fade" and allows for more consistent damping performance. They also provide easier access for adjusting the compression and rebound settings.

How do I adjust the compression and rebound settings?

The compression and rebound adjustments are typically made via knobs or dials located on the external reservoirs. Each position offers a distinct change in damping force, allowing you to fine-tune the suspension's behavior.

What is the purpose of camber-adjustable top mounts?

Camber-adjustable top mounts allow you to precisely alter the angle of your wheels relative to the vertical axis. This is crucial for optimizing tire contact patch during cornering, which can significantly improve front-end grip and handling performance on a track.

About this part

Product Details

AST is known for building serious suspension components for track use, and these 5200 Series coilovers are a prime example. If you're looking to push your 2017-2021 Renault Megane 4 RS B9 FWD to its limits, this kit is designed to give you the control you need. They feature a MONOTUBE coilover design with external reservoirs, allowing for separate adjustment of compression and rebound damping. This means you can dial in the suspension's response to match track conditions, tire choice, and your driving style, affecting everything from body roll in corners to how the car handles bumps.

The real advantage here is the independent adjustment of both compression and rebound. With 12 distinct positions for each, you can fine-tune how quickly the suspension compresses and how fast it returns. This level of adjustability helps you achieve better tire contact with the road for improved traction and can also be used to manage ride comfort. The inverted strut design is built to handle the significant side loads from hard cornering and the forces from heavy braking. This kit also includes camber-adjustable front top mounts and solid rear top mounts, giving you the ability to alter front-end geometry for even more grip.

This set comes complete with springs and all the necessary top mounts for installation. The external reservoirs allow for easier access to adjust damping settings, even when the suspension is under load. This is a comprehensive package for anyone serious about optimizing their vehicle's performance on the track.
