I picked these up from Tirerack knowing I wanted an extreme summer tire. I had them delivered with a set of silver TRM C1M 15x7 30 offset wheels. Both the wheels and tires look fantastic. While I have had limited opportunities to experience the grip, I fully expect them to perform beautifully. A 20 minute track session in the rain was actually enjoyable as I felt supremely planted even with the wet conditions. And one autox in the dry with the tires barely scuffed went well with little drama. My '99 Miata is running on new Tein coil overs so it will be interesting to see how the tires perform this summer as the various track days that are coming up. But, I am very pleased with the tires except just one little thing....they do tend to sing a bit around 65-70 mph. So the comments regarding noise are spot on. Sad to hear they are being replaced with new versions from Dunlop, but I would buy them again in a heartbeat. Very satisfied!
