The GSI Ultra 300 mm Wheel Rim is the flagship GSI wheel rim, a 300mm rim engineered for precision, comfort and seamless integration with the GSI Interlock system. Built on a rigid alloy core, it delivers uncompromising stability and direct force feedback response, while its shape supports natural ergonomics for long stints and consistent performance at the highest level. Its standout feature is the integrated LED Matrix — built directly into the rim — that keeps vital telemetry always within view, with no distractions, just data where you need it most. Designed exclusively for use within the Interlock System.

Yes. It features an integrated LED Matrix built directly into the rim, displaying real-time telemetry always within your line of sight.
Can I use the GSI Ultra 300 mm Wheel Rim on a non-GSI wheelbase or button box?
No. The Ultra 300 is designed exclusively for use within the GSI Interlock system and is not intended for use on third-party products.
What size is the GSI Ultra 300 mm Wheel Rim?
It has a 300mm diameter, an ergonomic, neutral size well balanced for multiple car classes.
