Increase your mid-corner and corner exit speeds by installing our Suspension Secrets Rear Camber Shim Kit for the Porsche 911 (991) GT3/RS/GT2 RS.

Negative camber is essential for track day setups as it increases cornering speeds and helps to make more efficient use of the tyre contact patch. As standard the Porsche 991 GT cars do not have enough rear camber for true track setups, thus necessitating rear camber shims.

Our Suspension Secrets Rear Camber Shim Kit for the Porsche 911 (991) GT3/RS/GT2 RS are simple and easy to install upgrade with the following benefits:

Increased negative camber on the rear axle

Improved mid-corner and corner-exit traction

Increased cornering speeds

Added transitional stability

Greatly reduced tyre wear

Easy to install

Our Porsche Rear Camber Shims Kit includes 12 shims of the following thicknesses:

4 x 1mm

4 x 2mm

4 x 3mm

By including a variety of thicknesses our shims can be stacked or staggered in order to create a camber setting that suits your needs best.

Suspension Secrets' products are designed and manufactured in the UK. Our products are made from billet aircraft-grade 6082 T6 aluminium and corrosion-resistant 316 stainless steel. We use motorsport-spec Fluro bearings for maximum performance and longevity.

Geometry Explained

Camber
Camber angle is the angle between the plane of a wheel and the vertical. It is described as positive when the top of the wheel leans outward and negative when the top of the wheel leans inward. Camber angle alters the handling characteristics of a suspension system.

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.
