I know what you are talking about when you say those rivet things are hard to clean. These are my wheels right now...
They are fun to clean though. I'm one of those types that don't feel that I'm accomplishing anything if it isn't hard work.

It makes "quick cleanings" hard to pull off and a full detail gets an extra hour added to it, but I think its worth it. I think I'm gonna get em. I can get a set of 4 17" rims with Z rated tires for around $900. Can't beat that.
