The stripe is vinyl. I was originally going to pick up a set of black Bullitts but these popped up on Craigslist for $350 with semi-good Kumho tires still on them. I couldn't pass them up for that price.
I have style #1. They are no longer making them so I got them cheap. $88 a tire. I have a good picture of my car on page 17 of the V6 picture thread. I'll get some uploaded to my profile soon.
