PORSCHE 992 GT3 Sport Steering Wheel 36cm Weissach Design RS Shift Paddle12

For the Porsche 911 (992 generation), the Weissach Design Sport Steering Wheel represents the absolute peak of driver interface technology. Found primarily in the GT3 RS and GT4 RS equipped with the Weissach Package, this wheel is often retrofitted to standard GT3s and even Carrera/Turbo models due to its distinctive feel and racing aesthetics.

1. Key Features & Design

Diameter: 36cm (360mm). This “Small Diameter” (GT Sport) sizing is the standard for modern Porsche GT cars, providing faster steering response compared to the 375mm-380mm wheels found in base models.
Magnetic Magnesium Shift Paddles: Unlike standard PDK paddles, these “Weissach” units use magnets to create a crisp, tactile “click” reminiscent of the 911 GT3 Cup car. They are made from lightweight magnesium and feature yellow +/- symbols.
RS Control Dials: The GT3 RS version features four rotary dials on the wheel to adjust:
- PASM (Suspension Damping)
- PTV+ (Differential Locking)
- ESC/TC (Traction Control)
- Drive Mode (Track/Sport/Normal
Material: Typically finished in Race-Tex (Porsche’s high-grip Alcantara) or smooth Nappa leather with a yellow or silver 12-o’clock top marker.

2. Part Numbers & Identification

Because these are high-value, high-precision parts, identification is critical:

Component	Part Number (Base)	Details
Complete Steering Wheel	`9GT419091`	Base number; suffixes vary by stitching color.
Magnetic Paddle Kit	9GT998540C5Q0	The full installation kit for the Weissach shifters.
Left Paddle (Magnesium)	`9GT927197B5Q0`	Individual magnesium replacement.
Right Paddle (Magnesium)	`9GT927198B5Q0`	Individual magnesium replacement.

3. Compatibility & Retrofitting

Standard 992 Compatibility: The Weissach paddles can be retrofitted to any 992-generation steering wheel (Carrera, Turbo, GT3). It is a “plug-and-play” mechanical swap that significantly improves the shifting feel of the 8-speed or 7-speed PDK.
Control Dial Functionality: If you install a full GT3 RS wheel with the four dials onto a standard Carrera, the dials will not function without extensive aftermarket modules or custom coding, as the Carrera’s ECU lacks the “Track” mode communication protocols.
Airbag Warning: You must reuse your existing 992 airbag or purchase one specific to the 992 frame. 991.2 airbags look similar but have different internal mounting clips
