Wheel Rims
Built to Adapt
Interlock System
Every racer has a different vision for the perfect wheel. That’s why Interlock comes in three versions — each a complete package in its own right, yet all built on the same modular foundation.
Ultra
The flagship of the system. A unique GSI rim with the LED Matrix seamlessly built in, interchangeable grips, and your paddle configuration choice.
Base Module + Rim
A complete package with your choice of GSI rim: GT 320 mm, GT 300 mm, or Oval 320 mm. Configure it with or without the LED Matrix to match your style.
Base Module
The foundation for your own wheel. Compatible with rims using a 70mm bolt pattern that meets clearance requirements. Add the LED Matrix for rims with a 55mm horn hole.

The Details
Powerlink-QR Ready
Since the beginning, we’ve pushed boundaries to create the ultimate sim racing products. The Interlock sets a new foundation for the future, built around our latest electronics and modular design.
It’s already prepared for our upcoming GSI Powerlink-QR, our next-generation passthrough QR that provides both power and data, with a conventionally placed USB-C port beneath the hub for effortless connectivity. The Interlock is ready not only for the GSI Powerlink-QR but also for any passthrough QR that uses a USB-C connection—no need to open the wheel to adapt. It also features dynamic power switching, intelligently recognizing whether it’s connected through the passthrough QR or the coiled cable—giving you seamless flexibility and complete freedom in how you connect.
simOS Architecture
GSI wheels run on simOS, our custom firmware optimized specifically for sim racing.
It includes features like predictive algorithms to optimize responsiveness and intelligently manage power and data, as well as a suite of useful features that integrate directly with the simOS app.
