Although the work on blacking out the chrome on my Model S won't be finished until tomorrow afternoon, I did get the arachnid wheels installed yesterday. They were power coated in black chrome, which is a three stage process. First they're powder coated in black. Then a metalized deposit is applied. Finally a third layer of clear coat finish is powder coated on top of that. I used spacers to get the outer edge of the tires flush with top edge of the wheel well. Given the section width of the Michelin Pilot Sport tires and the 40mm offset of the arachids, this required 30mm spacers on the front and 20mm on the rear. Here are a few photos of the results. It's a very aggressive look and exactly what I had hoped for. Will post more photos tomorrow of the entire blacked out car. The blacked out headlamps are a real benefit but I had them done some time ago.
