After some initial mock up, I've determined the Viper calipers on these rotors will not work. They stick out too far and contact my wheel. No worries. Time to move to plan B. Mustang GT 500 14" rotors and calipers. Good news is I should be able to use the FMJ rotor/hub for those rotors too. They should be the same, just 3/4" bigger. These calipers will be for sale.
I also ordered Hotckiss shocks and front sway bar back in December and the shocks just came in. The sway bar is still on back order. I can't believe how much better the ride is. I just assumed the sometimes clunky, rought ride was the larger diameter torsion bars. I was wrong, it was the shitty KYB shocks. Worth the wait and the money.
