Quick Answer
Choose the GXL V2 if you want a screenless formula-style wheel with all the inputs for open-wheel racing. Choose the Ultra 300 mm if you prefer a round rim with a rigid alloy core and LED Matrix for GT and multi-purpose driving.
Shape and Driving Style
The GXL V2 is a formula-style wheel, designed for open-wheel and high-downforce cars where your hands stay in a fixed position. Its screenless silhouette keeps the cockpit clean while still offering the same number of inputs as the FPE V2.
The Ultra 300 mm is a round rim, better suited for GT cars, drifting, and rally where you need to cross your arms or rotate the wheel more than 180 degrees. The 300 mm diameter gives you a balance between quick steering and leverage.
Inputs and Features
Both wheels offer extensive controls, but the GXL V2 retains the same number of inputs as the FPE V2, making it a feature-rich option for drivers who want maximum button and switch access without the screen.
The Ultra 300 mm focuses on a different priority: stability and direct force feedback response. Its rigid alloy core ensures the wheel doesn't flex, so you feel every detail from the road or track.
Compatibility and Integration
The Ultra 300 mm is part of the Interlock system, meaning it's designed for seamless integration with GSI's quick-release ecosystem. This is a key consideration if you already own Interlock components or plan to build a multi-wheel setup.
The GXL V2 is a standalone wheel that doesn't rely on the Interlock system, so it may be a simpler choice if you prefer a single-wheel setup without the need for interchangeable rims.
Trade-offs to Consider
- Wheel Shape vs. Versatility: The GXL V2's formula shape is optimized for open-wheel cars but limits hand movement. The Ultra 300 mm's round shape is more versatile for different car types but may feel less specialized for formula racing. If you race multiple disciplines, the round rim offers more flexibility.
- Screen vs. No Screen: The GXL V2 has no screen, which reduces visual clutter but requires you to rely on external displays or software for telemetry. The Ultra 300 mm includes an LED Matrix, providing vital telemetry at a glance without a full screen. Decide whether you prefer a clean look or integrated telemetry feedback.
- Interlock System vs. Standalone: The Ultra 300 mm is part of the Interlock system, enabling quick rim changes but requiring compatible components. The GXL V2 is a standalone wheel, simpler to mount but less expandable. Consider your future plans for multiple rims or quick-release upgrades.
