Adapter Ascher Racing 76080007 for Steering Wheels — 70 mm Bolt Pattern

The Ascher Racing 76080007 adapter provides a 70 mm bolt pattern interface for mounting compatible steering wheels to racing bases, quick-release hubs, or custom sim rig setups. It is engineered to align bolt holes precisely and maintain correct spacing for wheels that use a 70 mm pitch circle diameter (PCD), allowing secure and repeatable attachment in simulation cockpits and wheel swaps.

Advantages

The adapter offers precise hole alignment and stable clamping to minimize play between the wheel and the base. Machined tolerances ensure consistent fitment across repeated installations, while durable construction supports repeated use in simulation and casual racing environments. The compact form factor preserves clearance around the hub and quick-release mechanism.

Suitable for

• Mounting steering wheels with a 70 mm bolt pattern to sim bases and quick releases
• Wheel swaps between different hubs and cockpits
• Home racing simulators, training rigs and esports practice setups

Key specifications

• Bolt pattern: 70 mm pitch circle diameter (PCD)
• Material: machined metal construction for strength and stability
• Form factor: compact adapter designed for minimal added offset
• Compatibility: fits wheels and hubs designed for a 70 mm PCD interface

How to use

Align the adapter with the wheel or hub so the bolt holes match the 70 mm pattern, insert the appropriate bolts and tighten evenly in a star sequence to secure the connection. Verify alignment and torque according to the wheel and hub manufacturer recommendations. After installation, check for any axial or radial play and re-tighten fasteners if necessary before each session.

Recommendations

Use bolts and torque settings recommended by the steering wheel and hub manufacturers. Inspect the adapter and fasteners periodically for signs of wear or loosening, and replace any damaged parts to maintain safe, stable mounting in simulation use.
