Product Description

The MOMO 157 hub adapter lets owners of classic BMW E12, E21, E23, and E24 models - along with the E3/E9 2800/Bavaria and M1 - swap in a MOMO or compatible 6-bolt aftermarket steering wheel in place of the factory unit. The splined aluminum base is matched to the factory steering shaft, while a collapsible steel center section is engineered to deform under impact, helping absorb energy in a collision rather than transferring it straight to the driver.

It's a common upgrade for owners restoring or modernizing the driving feel of a vintage BMW without altering the factory column. Because fitment spans several chassis and model years with some overlap and exceptions noted by different retailers, buyers should double-check exact compatibility for their specific model year before purchasing, and confirm horn/wiring compatibility since some rewiring may be needed depending on the car's setup.
