SIMAGIC QR70 – Quick Release for GT1 and P-325D Steering Wheels

Designed for full-size GT steering wheels

The SIMAGIC QR70 is a strong, rigid quick release developed for larger diameter wheels with higher rotational inertia. It is the recommended choice for GT1 and P-325D steering wheels where maximum stability and force feedback transfer are required.

70 mm – motorsport-style interface

With its 70 mm pattern, the QR70 follows a layout similar to real-world racing applications. The larger contact area provides:

• increased connection stiffness,

• no unwanted play or micro-movement,

• stability even with powerful Direct Drive wheelbases.

Perfect for bigger, heavier GT wheels.

Precise locking – no slack in the connection

The locking mechanism minimizes axial and lateral play between the wheel and the base. Every steering input is transmitted accurately and consistently.

CNC-machined aluminum construction

The QR70 is made from CNC-machined aluminum, offering:

• high durability,

• solid stiffness at reasonable weight,

• reliability under intensive simracing use.

Fast wheel changes

Despite its larger diameter, the QR70 still enables quick, tool-free wheel changes in just a few seconds.

Compatibility

• QR70 is intended for:

  • GT1 series steering wheels

  • P-325D series steering wheels

• It can also be used wherever maximum stiffness is preferred.

• Note: for other SIMAGIC steering wheels, the appropriate quick release is QR50.

Solution for large GT wheels

QR70 is the quick release for users running full-size GT wheels and looking for a stable, rigid connection to the base – suitable for both home rigs and more advanced training setups.
