Suspension Secrets Camber Caster Plate Top Mounts – Porsche 911 (991) GT3/RS/GT2RS

Unlock more front-end grip, steering feel, and geometry control with the Suspension Secrets Adjustable Camber & Caster Top Mounts for the Porsche 911 GT3, GT3 RS, and GT2 RS (991).

While the 991 GT cars offer front camber adjustment from the factory, the range is limited—especially when running high-grip tyres like the Michelin Cup 2 or Cup 2R. Many drivers resort to control arm shims, which can push the wheels forward and cause tyre-to-arch interference.

Our top mounts solve this by repositioning the damper mounts with a wider camber range and built-in caster offset. The result is increased front axle grip, reduced understeer, and enhanced steering feedback—especially under high-speed cornering.

These mounts are fully compatible with OEM dampers and PASM systems, making them ideal for fast road and track-focused builds.
