Not sure what the difference other than the pistons for the caliper. Rotors are still 15 and 13, why are the rotors different? I have the Non performance pack GT, Want to upgrade the rotors and pads. Steeda has a good deal for PP GT Rotors and pads. Thanks.
Not Decided on what I want to go with. I've had good experience with Vortech. I had a twin screw on my last stang. Good torque, but broke all suspension and tranny parts it could. "Instant Torque" Been researching Vortech/Paxton, Procharger and VMP. Feed back would be helpful. Thanks
