After recommendations and reviews from Mustang owners in our local club, I’m going with Firestone Firehawk Indy 500s in 275/40/R19. For $730 installed, I just can’t say no. A Viking Funeral (i.e. BURNOUT) will be had for the P-Zeros before the new tires arrive. 

Will report how they compare on the road and Cars & Coffee when installed.
