9M Rear Camber Plate Top Mounts – Porsche 981 / 718 GTS

Improve rear-end grip, tyre performance and handling precision with Suspension Secrets Rear Camber Plate Top Mounts for the Porsche 981 and 718 Cayman GTS.
Designed for fast road driving and track use, these precision-engineered Porsche Cayman GTS camber plates provide a significantly greater range of rear camber adjustment compared with the factory suspension setup.
The stock GTS rear suspension offers up to -1.6 degrees of negative camber adjustment. With our Stage 1 'Fast Road' rear top mounts installed, it's possible to achieve -2.1 degrees of negative camber on standard springs, and up to -3.0 degrees on lowering springs (measured on 30mm H&R springs; all figures are ride height dependent).
Our Stage 2 'Track' rear top mounts provide up to -2.6 degrees of negative camber on standard springs. If your GTS is equipped with lowering springs, our Stage 2 rear camber plates can achieve up to -3.5 degrees of negative camber (ride height dependent).
Manufactured in-house in the UK from billet 6061-T6 aluminium and fitted with motorsport-grade spherical bearings, these Porsche Cayman GTS camber plates are a direct replacement for the factory rear top mounts and remain fully compatible with OEM dampers and PASM suspension.
Limitations of the Standard Porsche Cayman GTS Rear Suspension
Both the Porsche 981 Cayman GTS and 718 Cayman GTS feature limited rear camber adjustment from the factory.
The standard rear suspension top mounts use a fixed mounting position, restricting the total camber adjustment available during a wheel alignment.
For everyday driving this may be acceptable, but when the car is driven harder or fitted with track-focused tyres, the limitations quickly become noticeable.
Common handling complaints include:
Reduced rear grip during hard cornering
Excessive outer shoulder tyre wear on rear tyres
Rear-end instability during high-speed driving
Reduced traction when accelerating out of corners
Increasing rear camber is one of the most effective ways to improve rear tyre performance and overall chassis balance on the Porsche Cayman GTS platform.
This is why many enthusiasts install Porsche Cayman GTS camber plates to allow proper suspension geometry setup.
For drivers looking for a serious Porsche Cayman GTS suspension upgrade, these rear camber plates allow the alignment settings required to unlock the full performance potential of the Cayman chassis.
Suspension Secrets Porsche Cayman GTS Camber Plates
Our Suspension Secrets Porsche Cayman GTS rear camber plates reposition the rear damper mounting point using a carefully engineered offset design.
This increases the available camber adjustment range while maintaining correct suspension geometry and wheel positioning.
Unlike improvised alignment solutions, our Porsche Cayman GTS camber plates provide a precise and reliable method of increasing rear camber without compromising suspension travel or mounting integrity.
The result is a clean and effective solution for drivers looking for Porsche Cayman GTS camber plates that allow proper suspension setup for fast road or track driving.
With the additional adjustment range available, the rear suspension can be configured with more aggressive camber settings to maximise tyre performance and improve overall handling balance.
