OK this will be short and sweet as I can make it. When I bought my wheels the center caps from Rota did not fit. So after a while I got sick of looking at rusty axle and grease cap and made them fit.

Here is how I did it for a few bucks.

First, buy 4 of the chrome 1 3/4"Cock Hole Covers (I kid not) from the plumbing section, and a pack of 4 1 7/8" rubber furniture bumpstops.

You need to cut out the backs of the stoppers to make more clearance for the axles. The furniture bumpstops, I also ccut out the middles.

I removed the stock Rota stickers/middles and cut out a hole big enough for the axle to fir through for the fronts, and big enough to clear the grease hubs for the rears (if I were to do it again I would make big holes on all 4 for tire rotation purposes - otherwise you have to switch the center caps when you rotate your tires - PITA and the retaining clip thingeys break easily)

I used epoxy to glue the bumps to the stoppers together and then glued them to the center caps.

Necessity is truly the mother of invention. Makes you look in the plumbing section with imagination. Ask me how I know..
