Ford Mustang Shelby GT350/GT350R Chassis Detailed: The More We Learn, the More ... - Car and Driver (blog)
Brakes For example, the GT350 and the even racier GT350R will come with a very powerful and sophisticated braking system. The front rotors are 15. 5 inches in diameter, while the rears measure 14. 9 inches. Moreover, the rotors float on a circle of pins that connect them to the aluminum mounting hats. The calipers themselves are made by Brembo—there are one-piece, six-piston units in front and one-piece four-piston pieces in the rear. These calipers are unique to the GT350 with their own piston sizes and are radially mounted in the front, which means that their mounting bolts screw into the uprights parallel to the brake rotor rather than perpendicular to it. This radial... It also reduces heat transfer from the rotor to the hub, which helps wheel-bearing life. To minimize fade, dedicated brake ducts front and rear feed air to the ventilated rotors. Those radially mounted front calipers attach to new aluminum uprights that have different suspension pickup points than the standard Mustang. this is to accommodate the wider wheels and tires. Standard Mustangs have front wheels between 7. 5 and 9. 0 inches wide, while the GT350 gets 10. 5-inch-wide front wheels and 11. 0-inchers out back. Source: blog.caranddriver.com
