I'm sorry but Potenza's are crap. Which is probably the reason you're selling them. I had them on my Z and my RX8 in the past (stock tires). Couldn't wait to wear them out and get new ones. Went with Goodyear on the RX8. Traded the Z before needing them. The Michelins on my RC350 have to be the best tires I've ever had. But good luck to you!
