GSI GT 320 mm Wheel Rim

GSI GT 320 mm Wheel Rim – Alloy-Core GT Rim for the Interlock System The GSI GT 320 mm Wheel Rim is a 320mm GT-shaped sim racing wheel rim engineered on a rigid alloy core, designed to provide a stable platform for precise control and accurate force feedback response. Its larger 320mm diameter offers extra leverage and a more relaxed, road-car-like feel, while the motorsport-inspired shape supports natural ergonomics for long sessions and consistent performance. Built around a 70mm PCD bolt pattern for broad compatibility, the GT 320 works seamlessly with the GSI Interlock system as well as most sim racing button boxes, and features a 55mm horn cutout for LED Matrix compatibility. Available in Perforated or Suede finish, with an optional LED Matrix center.

Both share the same alloy core, 70mm PCD bolt pattern and LED Matrix compatibility. What bolt pattern does the GSI GT 320 mm Wheel Rim use? The GT 320 mm Wheel Rim uses a 70mm PCD bolt pattern, giving it broad compatibility with the GSI Interlock system and most sim racing button boxes. What materials is the GSI GT 320 mm Wheel Rim available in? It is available in two finishes: Perforated and Suede. Both are built on the same rigid alloy core. Can I add an LED Matrix to the GSI GT 320 mm Wheel Rim? Yes. The rim offers an optional LED Matrix center and features a 55mm horn cutout for LED Matrix compatibility. The GSI Interlock Base Module is required for the LED Matrix to work. Is the GSI GT 320 mm Wheel Rim compatible with non-GSI button boxes? Yes. As long as your button box uses a 70mm PCD bolt pattern, the GT 320 mm Wheel Rim will fit. It also integrates directly with the GSI Interlock system.
