The Suspension Secrets Porsche Strut Tower Protection Package is a proven suspension upgrade designed to help prevent front strut tower failure on Porsche 718 / 982 Cayman GT4 RS models. 

Front strut tower failure is a known issue on hard-driven Porsche GT4 RS models, particularly on cars used for track days and motorsport. When lowering the GT4 RS, bump travel is significantly reduced in the OEM front dampers. This can cause the dampers to bottom out over large compressions or kerbs, sending large shock loading forces directly through the damper piston into the top mount assembly. This can result in deformation, cracking or costly chassis damage.

This Suspension Secrets package combines our front camber caster plate top mounts with our uprated spring cups that allow you to lower the car and keep enough bump travel in the OEM damper to prevent this bottoming out effect. By improving the damper travel at the lower ride height, this package helps protect the front strut towers from damage while also improving suspension geometry, steering feel and front-end grip; making it an upgrade as well as providing protection and preventing damage from occurring. 

Please note that this solution only works as a package. The spring cups must be paired with the Suspension Secrets top mounts in this kit for the solution to work. 

This solution fully prevents the failure from occurring by removing the root cause of the problem as opposed to enhancing the strut tower strength to take the loads from the damper bottoming out. 

This kit includes:

  • 1 Pair of Suspension Secrets Front Camber Caster Plate Top Mounts
  • 1 Pair of Suspension Secrets Front Spring Cups

With the Suspension Secrets Performance Strut Tower Protection Package installed to your GT4 RS you will benefit from:

  • Strut tower damage prevention and protection
  • The ability to lower your GT4 RS without causing strut tower damage
  • Increased camber and caster range
  • The ability to install track focused alignment settings 
  • More front axle grip and reduced understeer
  • Improved front tyre wear on track
  • Fully compatible with PASM and OEM Dampers and Springs 
Geometry Explained

Geometry
Suspension geometry is the positioning and angular movement of the suspension arms and the effect that they have upon the movement of the wheel and tyre. It is caused by the different components of the suspension system all moving in their designed paths, which together generate changes in direction and multiple forces on the wheel and tyre, making the steering and suspension operate in particular ways.

Supplied and fitted by the team at Suspension Secrets along side their solid front control arm bushes and Eibach Pro springs. I cant recommend this enough, stability and grip are on another level. A* service provided by the team from start to finish. Highly recommended!

Effortless & Accurate

The results have exceeded my expectations, I'm really pleased with the car. The ride is similar to stock but it's taken the jitteryness away over small ripples in the road. I was slightly apprehensive that the stock dampers might be exposed but I needn't have worried, the car rides exactly as I'd expect & want from a roadgoing M-car. The real revelation is the steering, I could feel the difference as soon as I turned out of your premises. Gone is the sluggish, heavy response - it's now quick, effortless & accurate, almost as if the power steering had been switched off beforehand. The car feels like it's 200kg lighter but at the same time, more solid & composed. For me, it's a perfectly-judged road setup - thanks again

Recently bought a 2025 M3 LCI which seemed ok out of the box. In the wet there was quite bad understeer and slightly unpredictable transition into oversteer. The CS+ handling package transformed the car. The grip is ridiculous, feel is improved, can really lean on the car. Driving in the wet traction is like it’s dry, extremely stable. Car is predictable, any transition to understeer or oversteer is communicated and feels like slow motion with plenty of time to correct. Feel like all the handling of a CS car with all the comfort or a regular M car. Absolutely love the car now.
