AST Adjustable Top Mounts - Renault Megane 4 RS

The lack of adjustment: the weak point of your Megane 4 RS

Despite the formidable efficiency of the Megane 4 RS, its front end remains limited by fixed factory settings. By not upgrading to these AST adjustable top mounts, you are missing out on optimized geometry, which is indispensable for Trackdays. Without camber adjustment, you will suffer from premature wear on the shoulders of your tires (such as Michelin Cup 2 or Pirelli Trofeo R) and frustrating understeer upon corner entry. Keeping the original rubber mounts means accepting front-end deflection under heavy load, which harms the precision of your Cup or Trophy chassis.

  The absence of rigid uniball joints means you lose a portion of the steering "feedback." Every parasitic movement of the original bushings is a piece of information lost to the driver. Don't let a mass-produced setup limit your lap times and driving pleasure.

AST Suspension Technology: Adjustment without compromise

The strength of this AST Suspension kit lies in its ability to be mounted directly onto your original dampers. This gives you the ability to adjust your negative camber while maintaining the comfort and embedded technologies of your factory suspension. It is the ultimate step in technical customization for those who want "race-ready" efficiency without switching to complex coilover systems. Manufactured from aerospace-grade aluminum, these plates offer exceptional rigidity and proven durability in competition.

Frequently Asked Questions about AST Top Mounts

Does the installation change the ride height?
These mounts are designed to maintain a near-factory ride height while replacing the upper mount/bearing assembly with a much more rigid spherical joint system.

Is the camber adjustable once the mounts are installed?
Yes, the design allows for camber adjustment over a wide range, letting you switch from a "street" setup to a high-performance "track" setup.
