Well, my wheels arrived.....oh so happy...only, I don't have center caps
The wheels are 18" Porsche Competition
I thought they were both ET52, but only the front is ET52, the rear is ET 47....
Here's a couple pics:

18x8.5 inches of front wheel goodness

18x10 rear....look at that lip...well, pics can't show it too well, all the shiny-ness, lol

front and rear respectively...mmmm....contact patch.
