Went to the PBIR with the Mustang! Performed a check ride with a Miata driver to proceed to advanced and did some driving with our 2016 Mustang Ecoboost. We decided to switch out the tires from the stock Pirelli P-Zero tires to the cheaper Hankook Ventus V12 Evo2 tires, and the differences are immediately noticeable. Grip is significantly reduced and overall performance is reduced (braking, mid-corner throttle, etc). Next time we’ll be switching back to the stock P-Zeros!
