The MOZA ES Formula Wheel Mod is a replacement rim that changes the round ES steering wheel to a Formula-style shape for sim racing setups built around the MOZA ES wheel.
With a 280 mm diameter, an aviation-grade aluminum body and rubber grips, it offers a different hand position from the round ES rim while retaining use with the ES steering wheel.
MOZA specifies this rim for the ES wheel. It is a component for changing the steering wheel format in a sim racing setup.
