Steering wheel hub adapters are required to install 6 bolt Sparco or NRG wheels into your vehicle. If you're looking to install a steering wheel this is required, you can ADD a quick release, but a quick release will not act as an adapter hub.
Picked this up along with the 2.0 quick release to help getting in and out of my miata with its new seat. Fit and finish of the product is of the highest quality and I would recommend it to a friend.
Bought this hub from Fab9, was at my door a couple days later. Paired with the quick release 2.0, it looks great in my NB. Install was pretty easy after looking into some videos. Would highly recommend this to anyone who wants to run an aftermarket steering wheel.
