Bridgestone Potenza RE-71R 205/45R17 88W XL Performance Tire

I've competed in autocross events regularly for the last fifteen years. I've run many vender's R-comp tires. The 200 treadwear RE-71R seems to nearly match the dry performance of several of the R-comp tires and in my opinion, maintains that outstanding performance through twice the R-comp life on a heavier "pony car". I'm driving a 2015 Mustang GT with performance pack, Koni's, and larger anti-sway bar on 285 x 35 x 19 (Rear) and 265 x 35 x 19 (Front) RE-71R's. I consistently record lateral g-forces in excess of 1.15 g's through 50 - 60, (approximately 0.8 mile) autocross runs on concrete. If you want to be competitive in the SCCA street classes, I recommend these. I'm on my third set. My reported mileage may appear low, but I count autocross runs to evaluate my autocross-purposed tires. These hold up very well.

best tire I use for autox and hillclimbing hands down lap times 1/2 second faster then the hankooks v3
