Using them right now. I'm not a huge fan of them for autocross. I think the Dunlops that came on the car were a little bit better. My decision was between the Kumho's and the Yokahama A520's and I am thinking I might have done better going $20 per tire more and going for the Yok's For regular street driving they are a perfectly good tire with pretty decent rain handling. They don't cost a fortune either! I'm solving my problems with autocross tires though and getting a set of Kumho Ecsta V700's. These are real sticky! I'm only goint to use them for auto-x.
