We are running 16X11's using the Works style over fenders, the wheels fit nicely under the overfender. We had them in fiberglass, the set we have came from Japan. We commissioned a mold to be made so that we could get them made in CF. We are using Thunderranch for our parts. www.thunderranch.com
There is a company in Japan that makes all these parts, I know Alan from Great Britian knows the website of the company. I used to have it.
