Thanks Bobby,
Yes I will use these for Autocross and some limited street, although my car is setup for DE.
I needed to order yesterday and read what I could find. I guess if they don't work well I'll try something else next year. I have over 2 deg of neg camber front/back. I heard the new Direzza are more dependent on setup. I didn't read/know much about the small difference in diameter effecting gearing that much.

If Phil had tires probably perfect. or Damon at Tire rack is who I work with. I'm old fashion and started with MPSC =- I have 3 sets of wheels and too committed to change. I know what to expect. I've been through the tire tread seperation syndrome with imported tires etc. The older I get the faster I was so I just want to be safe. Michelin has never failed me. BFG has Goodyear has, Firestone & Kumho. And the Dunlop disappointment with their second variant being discontinued for my street tires
