| Those who have read the " Improved Ergonomics " and " Driving Position " sections of this website realize that I am a big advocate of moving the steering wheel closer to the driver. One way to move the steering wheel closer is to install a spacer between the wheel and the adapter hub. That was what I originally did on my E30 M3 - with a 1.5" spacer that I made myself. |
But I recently installed a Terazoom
quick release steering hub on my M3. The Terazoom hub is similar to the
Q/R mechanism available from
Smart Racing Products .
The Terazoom Q/R hub has a taller stack height than the standard Momo
adapter hub and thus functions as a spacer. But since it is also a quick release mechanism,
it offers easy ingress/egress from the driver's seat, as well as a margin of safety at the track
should you have to extricate yourself from your car in a hurry.

It should be noted though, that this quick release hub adapter is designed for racing. It is not intended for highway use as there is no provision for a horn or for and airbag. Also, the Momo adapter's "crush" zone is removed from the hub upon conversion to the quick release function. Lastly, since you are moving the steering wheel closer to the driver, it is more likely that the driver might contact the steering wheel during an accident. That being said, my 1988 M3 never had an airbag, and I removed the horns long ago as they interfered with the brake ducts. I have one of these quick release hubs installed and I love it. The car is used mainly for track and auto-x but it does get driven on the street. So I made a conscious decision to accept the ramifications of the quick release hub. |

This photo shows the Terazoom quick release hub in comparison to a standard Momo adapter hub. It is apparent that the Q/R hub uses a Momo hub for its base. You do not have to bolt the quick release mechanism to a Momo adapter hub - the Q/R hub already incorporates the adapter portion. You just install it and go. |
