BMW Steering wheel adapter big to narrow spline

A steering wheel adapter makes possible to fit a BMW steering wheel originally manufactured for a different model, and which cannot be fitted directly because of different attachment.

In this version we offer the adapter to mount the BMW  5, 6 and 7 series, steering wheel, built by BMW factory with larger diameter (about 21 mm) steering shaft, on the 1 Series, 2, 3, 4 equipped with  narrow steering shaft (about 18 mm)

The 2 steering wheels look the same when mounted on the car, but they are different inside.

How are they different? Only in the center hole. The steering wheels of the smaller BMW series, up to the 4 Series, have a central hole with a smaller 18 mm diameter splined bore, while the steering wheels from 5 to 8 series BMW have a central bore with a larger 21 mm diameter.

We have used our experience in the machining process of the splined bore / shaft to build an adapter that allows you to mount the 3-spoke steering wheel from a 5, 6, 7 series on a 1, 2, 3, 4 series,

The installation of the adapter is simple and reversible, in case you want to disassemble from the car everything goes back to the way it was before.

There is no need for coding after installation.
