Sim-Lab XERO-PLAY Quick Release Guide: Motor Side, Wheel Side and Adapter Sizes
Quick summary· AI-generated
The guide walks through how the Sim-Lab XERO-PLAY quick release works—a rigid alloy-steel assembly that separates into motor-side and wheel-side components to transmit direct-drive torque while allowing fast wheel swaps. The critical step is selecting the correct wheel-side adapter by bolt pattern (70mm standard, 52mm Fanatec, 50.8mm Formula, 44.5mm Stock Car); the guide measures each and warns against assumptions based on brand name alone. Special compatibility notes are provided for Simucube 2 users. A practical reference for buyers integrating multiple wheels into one wheelbase setup.
Excerpt from Sim Race Webshop B.V. - Product Higlights
A quick release must do two jobs equally well: let you change steering wheels quickly and transmit direct-drive torque without detectable movement. The Sim-Lab XERO-PLAY system separates the parts into a motor-side base and a matching wheel-side adapter. Choosing the correct bolt pattern is therefore the most important step before installation.

Sim-Lab machines the quick release from alloy-steel components for a rigid connection under direct-drive forces and vibration. The motor side uses a conical shaft to centre the wheel side. To remove a wheel, pull the release ring and slide the wheel-side assembly away from the base. The combined assembly height is 65 mm, so it also changes the steering-wheel distance by that amount.
The system uses a 70 mm industry-standard pattern on the base side, while optional wheel-side adapters translate the wheel’s rear mounting pattern. The Shopify catalogue currently offers complete motor-side combinations and separate wheel sides, which is useful when adding a second wheel to one wheelbase.
The complete connection consists of a motor-side cone and a wheel-side adapter selected for the wheel pattern. Choose the wheel-side adapter by measurement
70 mm standard
Select the 70 mm six-bolt adapter for wheels and hubs that use the common 70 mm pitch-circle diameter. Count the holes and measure the circle; “six bolts” alone does not prove that the diameter is 70 mm.
52 mm Fanatec pattern
The 52 mm option is intended for relevant Fanatec-style mounting patterns. Check the exact hub or wheel rear plate rather than assuming every Fanatec product shares the same interface.
50.8 mm Formula pattern
This adapter targets formula-style hardware with a 50.8 mm pattern. It is a distinct size, not an interchangeable name for 52 mm. Check current availability on the product page because individual adapter variants can be temporarily unavailable.
44.5 mm Stock Car pattern
The 44.5 mm option fits compatible stock-car-style wheels. Confirm whether your rim mounts directly or requires a separate button box or hub between the rim and XERO-PLAY.
