03 · Hubcaps
Which hubcaps fit
Any early hubcap from a 1949–1965 Beetle, 1955–1967 Bus or early 356 Porsche will work, as will aftermarket caps for those models. Pick carefully: some are made with thinner steel or cheap chrome, so inspect before you buy. Hub caps mount with Wolfsburg West clips and 10-32 stainless socket head cap screws.
Do we sell hubcaps? No. Here are some options.
