Improve front-end grip, steering feel and handling precision with Suspension Secrets Front Camber Caster Plate Top Mounts for the Porsche 911 (991).

Designed for fast road driving and track use, these precision-engineered top mounts provide a greater range of front 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 offset mounting position provides increased alignment adjustment without pulling the wheel forwards in the arch. This allows a more effective fast-road or track alignment while maintaining the correct wheel position.

Manufactured in-house in the UK from billet 6061-T6 aluminium and fitted with motorsport-grade spherical bearings, they directly replace the factory top mounts and remain compatible with OEM dampers and PASM suspension.

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.

Caster
Caster is the measure of how far forward or behind the steering axis is to the vertical axis, viewed from the side. This is measured by drawing a line between the top and bottom pivot points of the front upright. The angle between the drawn line and vertical is the caster angle

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.
