The chassis is new from the ground up, with MacPherson-strut front suspension using reverse "L" lower control arms, which deliver both comfort and control.

For 2005, Mustang’s rear suspension has new three-link architecture with a lightweight, tubular Panhard rod that provides precise control of the rear axle. This technology stabilizes the rear axle as the wheels move, particularly during hard cornering.

The standard four-wheel disc brakes have the biggest rotors and stiffest calipers ever fitted to a mainstream Mustang. Twin-piston aluminum calipers clamp down on 12.4-inch ventilated front brake discs on GT models – an increase of more than 15 percent in rotor size. The V-6 Mustangs get 11.4-inch ventilated rotors that also are 30 mm thick.

In the rear, the brake rotors are 11.8 inches in diameter – more than 12 percent larger than on the 2004 model. Rear rotors are vented on the GT and solid on the V-6.

An optional four-channel anti-lock braking system is available for a greater degree of brake control. It uses electronic sensors to constantly monitor road conditions and feed the information to a dedicated control computer capable of determining, within milliseconds, whether the vehicle is on dry pavement or negotiating a slippery surface. When traction control isn’t desired – like when a smoky burnout at the drag strip is in order – drivers can deactivate the system with a simple button on the instrument panel.
