As used on all our race cars including the B46. We have found this adapter to be reliable with super smooth action and does not bind up or develop play like some other adapters on the market. 
 
Rennline has adapted Porsche Motorsport's engineering with their own style and design to give you the highest quality quick release hub on the market. Unlike similar units on the market, this hub has a tapered asymmetrical socket that eliminates any chance of looseness as the hub breaks in. Rennline Quick Releases are equipped with spring loaded roll pins to allow for a seamless one hand removal which is vital in any emergency situation. All critical components are precision machined from anodized 7075 aircraft grade aluminum and designed to work with the standard 6 bolt pattern found on most Momo, OMP, and Sparco wheels. This unit measures 2.3" tall. Available in Black.

Note: Horn function will be lost when installed. Designed for use in off-road vehicles only. Steering wheel and hub adapter not included.
