I had these Indy 500 tires for my track days on a s2000 for awhile now. They are far the best grippy tires for the price range. They share the similar design as Bridgestone RE11 which are also excellent tires for track days or autocross. I will definitely buy another set of these tires for next year's season.
I have the PSS in the size of 265/35ZR18 on my 800HP Honda S2000. They are amazing, i've used over 400 sets of tires in my life and these for the street are my favorite. I currently have 3 sets on rims ready to go. Thanks for a great tire Michelin, you never seem to disappoint.
