I love the Brooklands steering wheel, which was the standard Plus 4 wheel until 1968. The rim is thin, so I fitted a handsome leather wheel cover from an outfit in California for about $42.

I'm skinny enough that I can still use the 16.5 wheel, but most of the guys in my club are switching to the smaller wheel. They're available in several colors, although the leather covers most of the plastic.
