Suitable for attaching non-Simagic Wheels to the Simagic Alpha Evo Wheelbases 

Simagic Quick Release Adapter
Easily mount third-party steering wheels with a standard 50mm or 70mm PCD to your Alpha EVO wheelbase using this Simagic quick release adapter.

Unlock the ultimate connection between driver and machine with the Simagic QR-A Quick Release Adapter — a precision-engineered masterpiece inspired by real-world motorsport technology. Designed for seamless performance, strength, and reliability, the QR-A delivers professional-grade quick-release functionality for the most demanding sim racing environments.

Built from CNC-machined aerospace-grade aluminium, the QR-A provides an incredibly rigid, play-free connection between your steering wheel and direct-drive wheelbase. Every detail is developed to transfer steering input with unmatched accuracy, ensuring your simulator responds as instantly and precisely as a real racing car.

Engineered for Motorsport Precision

The Simagic QR-A uses a self-centering tapered locking system that guarantees a secure fit with zero flex or movement — mirroring the technology used in professional race cars. This mechanical precision allows for lightning-fast steering input and exact force-feedback translation, making it ideal for high-torque direct-drive systems.

The quick-release mechanism enables rapid wheel swaps without tools, supporting multi-wheel setups for different racing disciplines such as GT, Formula, Rally, and Drift. Whether you’re competing online or training in a professional sim lab, the QR-A ensures consistent, rock-solid performance every lap.

Seamless Integration and Durability

Built to endure the most intense racing conditions, the QR-A is designed for plug-and-play compatibility with non-Simagic wheelbases and Simagic steering wheels

The QR-A is compatible with Alpha EVO Sport, Alpha EVO and Alpha EVO Pro wheelbases.

Mounting: Supports 50mm or 70mm wheel / wheel hub mounting patterns.

The USB-enabled variant offers reliable, high-speed signal transmission for advanced wheel inputs such as paddle shifters, clutch bite point controls, and multi-function button plates — ensuring no input delay or data loss during competition.

Finished with anodized aluminium surfaces for long-term durability and aesthetic appeal, the QR-A embodies the quality expected in top-tier sim racing hardware.
