I just got a set for my track day and autocross Miata, and they are fantastic. My M2 just got the Yoko Advan AD08s replaced with BFg Sport Comp 2 and they are a very nice tire and not a substantial downgrade.
For you Autocrossers and Track Day nuts, you should seriousely consider the Rivals. Grassroots Motorsports (my fave mag) tested the Rivals in 205-50-15 and the Dunlop ZIIs in the same size and the magic Toyo R1Rs in 195-50-15 and the Rivals came on top.
Thanks to Andi Hollis and Andi Whitener, both Solo Champs for the testing.
