I highly recommend the MX's for a street performance tire. They do give up a bit of dry performance for wet handling (which is superb IMO), so if wet handling isn't a concern, I'd look at the Falken Alzennas (which David97gt46 has).
At the last AX, I was .3 off of David. Given our car differences and the obvious driver skill differences, I'd say it was not my tires holding me back. I've gotten them pretty hot on a few occasions with no signs of going greasy. Further, as they break in, grip continues to improve. They're great tires. Unless I go to some Alzennas, I'll be picking up another set when the time comes.
See ya tonight everyone. It looks like I'll be there. I had my yearly physical the other day and one of the practicianers just picked up a 91 GT so I convinced him to try and come out as well.
