Stop limiting your Porsche's factory adjustment potential! This pair of Front Spherical Bearing Top Mounts (Camber Plates) for the Porsche 991 GT3, 991 GT3 RS, 991 GT2, and 991 GT2 RS, engineered by Suspension Secrets, features a smart offset design. This offset significantly increases the range of negative camber and positive caster adjustment, which is crucial for maximum front axle grip and stability on the track. Without them, you cannot properly optimize the geometry for the track, leading to understeer and abnormal tire wear. Find complementary products at the bottom of this page.
Your Porsche 991 GT is already equipped with factory spherical bearing top mounts, a benefit for performance. However, during intensive track use, the adjustment range offered by the OEM equipment is often insufficient to achieve the necessary level of negative camber. Optimiz Access, an official Suspension Secrets distributor and expert in premium sports vehicle maintenance, offers these Top Mounts based on an offset design that pushes the limits of front geometry.
Keeping the stock top mounts, even the spherical ones, prevents you from achieving the precision required for optimal driving: You lose grip and suffer from understeer: The limit on negative camber achievable with factory parts prevents maximizing the tire contact patch when cornering, especially in medium and long bends. Without the extended adjustment range provided by these offset top mounts, the front axle grip is suboptimal, resulting in increased understeer and less competitive lap times. Your high-speed driving experience lacks precision: The increase in camber allowed by the offset improves steering feel and provides increased high-speed stability and accuracy. Without this upgrade, the car is less responsive, causing you to lose confidence during critical load transfers. You do not achieve maximum dynamic camber gain: These top mounts also increase front positive caster (Castor). This modification optimizes the dynamic camber gain, ensuring the tire angle becomes even more negative when steering lock is applied. Without this offset, the performance of your damper and the efficiency of your running gear are compromised. Suspension Secrets Kit Contents: This kit includes a pair of spherical bearing top mounts (Camber Plates) with CNC-machined aluminum bodies, featuring high-quality Motorsport-specific spherical bearings, optimized by an offset system to increase the adjustment range. The kit is designed for direct installation on your Porsche 991 GT (GT3, GT3 RS, GT2, GT2 RS).
These offset spherical bearing top mounts from Suspension Secrets do more than just replace parts: they redefine the limits of front geometry. The accumulated offset from the design allows a new mounting position for the front damper to the chassis, unlocking a crucial camber and caster adjustment range for competition use. By choosing Optimiz Access, your authorized distributor, you invest in the most advanced tool for the personalization of your 991 GT.
The installation principle is similar to a standard spherical top mount, but leveraging the offset requires great precision during the complete geometry alignment. Fitting and alignment must be performed by an expert workshop like Optimiz Access, which understands the optimal caster and camber settings for your track use.
The increase in positive caster (Castor) improves steering "self-centering," increases dynamic camber gain when cornering, and provides better straight-line stability—all essential elements for the performance and safety of Porsche GT vehicles at high speeds.
