Silver Rocket SR Porsche Motorsport Spec LCA Camber Shims & Socket Pack - 2022+ Porsche 992 GT3RS

The only camber shim kit for the Porsche 992 GT3 RS built to official Porsche Motorsport material specifications and stacking guidelines — the exact standard used by Porsche's factory works teams. Each shim uses the same material composition and heat treatment as those fitted to the 992 GT3 Cup and GT3 R race cars, delivering maximum strength, durability, and minimum weight. The kit includes a full range of shims for complete track and race adjustment, plus a custom socket designed to prevent damage to factory screws during installation.

Highlights:

• Custom socket for risk-free shim changes
• Complete kit for one Porsche 992 GT3 RS
• Genuine Porsche Motorsport specification camber shims
• Material- and thickness-specific construction matching factory race parts

Application:

• Porsche 992 GT3 RS

SILVERROCKET CUSTOMIZED LCA SOCKET FOR 992 GT3RS

The ISSUE - 992 GT3RS Control Arm

• The Control Arm on the Porsche 992 GT3 RS presents a significant difficulty during Lower Control Arm (LCA) shim replacement or camber adjustment. The factory-equipped M10 nut is now recessed halfway into a narrow machined slot.
• When using a standard M10 socket, the nut cannot be fully engaged. Furthermore, the limited clearance forces the tool to operate at an awkward angle. Applying torque under these conditions risks slippage, incomplete engagement, or potential damage to the factory control arm and surrounding components.
• Porsche Motorsport identified this clearance issue and addressed it on the 992 Cup cars by replacing the standard M10 nut with a customized low-profile nut designed for a 12 mm narrow socket. However, the original design remains unchanged on street-legal 992 GT3 RS models, so the issue persists.

The SOLUTION - Silverocket Customized LCA Socket

• To eliminate this issue and ensure safe, damage-free servicing, SilverRocket has developed a purpose-built Customized LCA Socket specifically engineered for the 992 GT3 RS aero control arm.
• This precision-machined tool is contoured to perfectly match the unique geometry of the control arm slot. It provides full, secure engagement with the M10 nut while maintaining a straight and optimal angle for applying torque. As a result, technicians can loosen or tighten the nut efficiently and safely, without stressing or damaging the factory components.

THE PINNACLE OF PRECISION: PORSCHE MOTORSPORT'S TAILORED APPROACH TO CAMBER SHIMS

In Porsche Motorsport's pursuit of engineering excellence, camber shims are not uniform. Different thicknesses employ carefully selected materials to optimise strength, durability, and weight — a deliberate strategy proven in the 992 GT3 Cup and GT3 R race cars.

Why Materials Differ by Thickness?

Thinner Shims (<2 mm)
These require maximum rigidity for precise, small camber adjustments (~0.1° per shim). Porsche specifies high-strength stainless steel (X5CrNi18-10) to deliver superior stiffness with minimal added mass. This prevents deformation, maintains laser-accurate alignment, and preserves the GT3 RS’s sharp handling response.

Thicker Shims ( >2 mm)
Designed for larger camber changes (~0.3–0.5° per shim) and higher compressive loads, these use aerospace-grade aluminium alloy (AlZn4.5Mg1). Precision laser-cut the aluminium significantly reduces weight and rotational inertia while maintaining structural integrity under extreme track conditions.
This material-specific approach ensures every shim performs exactly as intended — delivering race-proven precision, longevity, and performance without compromise.

PORSCHE MOTORSPORT LCA SHIM ISSUE: PRICE

The only significant drawback of the Porsche motorsport shim is the price. Porsche Motorsport lists these shims at above $57 per piece (MSRP).

SILVERROCKET SOLUTION: PORSCHE MOTORSPORT SPEC SHIMS

Unlike the 718 GT4 RS, where we were able to source heavily discounted Porsche Motorsport surplus stock through 51GT3.COM, no such option exists for the 992 GT3 RS.
SilverRocket therefore manufactures the camber shims to the exact same material specifications, heat treatment processes, and tolerances as Porsche Motorsport. This allows us to deliver genuine race-proven quality in a complete kit at a significantly more accessible price.

TECHNICAL SPEC OF SILVERROCKET 992 GT3 RS LCA PACK

Lower Control Arm Camber Shims are the official mechanism designed by Porsche Motorsport to adjust camber settings on GT/RS models.
When the 992 GT3RS leaves the factory, it already includes some camber shims or mount plate to support a more aggressive driving style.

However, Porsche provides the flexibility for customers to add additional camber shims for an even sportier setup. SilverRocket has measured on our 992.1 GT3 RS and provided the table below to clarify the factory preset and maximum allowed camber shim measurements (in mm).

ONE PACK FOR ONE CAR

To simplify the process for all GT3RS owners, SilverRocket has calculated the necessary camber shims for a single car and created this comprehensive one car pack.
