Improve front-end grip, steering feel and handling precision with Suspension Secrets Adjustable Camber & Caster Top Mounts for the Porsche 981 and 718 Cayman GTS.

Designed for fast road driving and track use, these precision-engineered camber plates provide a significantly greater range of Porsche Cayman GTS camber adjustment while adding up to +2.0 degrees of positive caster (depending on ride height) to improve steering feel, stability and cornering performance.

The stock GTS front suspension offers up to -1.0 degrees of negative camber adjustment. With our top mounts installed, it's possible to achieve -2.3 degrees on standard road springs, and up to -3.1 degrees on lowering springs.

Our Cayman GTS front camber plates also allow the fitment of Cayman GT4 front tyre size 255/35ZR20.

Manufactured in-house in the UK from billet 6061-T6 aluminium and fitted with motorsport-grade spherical bearings, they are a direct replacement for the factory top mounts and remain fully compatible with OEM dampers and PASM suspension.

For drivers looking for a serious Porsche Cayman GTS suspension upgrade, these camber plates allow the alignment settings needed to unlock the full capability of the Cayman chassis.

Limitations of the Standard Porsche GTS Top Mounts

Both the Porsche 981 Cayman GTS and 718 Cayman GTS feature adjustable front camber from the factory. However, the available adjustment range is limited due to the concentric mounting position of the original Porsche top mounts.

In most cases the maximum achievable camber is just -1.0 degrees, depending on ride height.

For everyday driving this may be sufficient, but when the car is driven harder or fitted with track-grade tyres, the limitation becomes clear.

Common handling complaints include:

• Mid-corner understeer
  

• Excessive outer shoulder tyre wear
  

• Imprecise turn-in response
  

• Front tyres overheating during spirited driving
  

Increasing front camber is one of the most effective ways to improve front tyre performance and overall handling balance.

Why Camber Shims Don't Work

You cannot adjust front camber on the GTS using shims due to a lack of space in the lower control arm assembly. The Cayman GT4 and GT4 RS are equipped with split coffin arms, which do allow the use of front camber shims.

The Suspension Secrets Solution

Our Suspension Secrets Camber Caster Top Mounts for the Porsche 981 / 718 Cayman GTS reposition the strut mounting point using a carefully engineered offset mounting position.

This provides significantly greater camber adjustment without pulling the wheel forwards in the arch. The result is a cleaner and more effective solution for drivers looking for Porsche Cayman GTS camber plates that allow proper suspension setup without compromising wheel position.

With our GTS top mounts you can achieve up to -2.3 degrees of front camber with standard road springs, and up to -3.1 degrees with lowering springs.

Our top mounts also incorporate up to +2.0 degree increase in positive caster (ride height dependent) compared with the factory mounts.

Increasing caster provides:

• Improved steering feedback and feel
  

• Greater steering weight and precision
  

• Increased high-speed stability
  

• Improved dynamic camber gain during cornering
  

The result is a more responsive and confidence-inspiring front end, particularly when driving quickly on road or track.

FAQs

How much camber can these mounts provide?

The exact camber available depends on ride height and alignment setup, but the offset design allows significantly greater adjustment than the factory mounts, enabling proper fast road and track setups. It's possible to achieve -2.5 degrees of negative camber with stock road springs, and up to -3.2 degrees with lowering springs.

Are they compatible with PASM suspension?

Yes. These camber plates are fully compatible with OEM PASM dampers and install directly in place of the original top mounts.

Are they suitable for road cars?

Yes. They are designed primarily for fast road and occasional track use, providing improved steering feel and suspension precision while remaining suitable for road-driven cars.

These Suspension Secrets camber and caster top mounts provide increased alignment adjustment for drivers looking to improve the handling balance and front-end grip of the Porsche Cayman GTS.
