The 15″ Magnum 500-style wheels are mounted with Goodyear Polyglas GT tires. The Boss 429 model was equipped with revised control arms, a higher-rate front anti-roll bar than other Mustang variants, a rear anti-roll bar, and a competition suspension with staggered rear shocks. Power-assisted brakes with discs up front and drums out back were standard on the 429, with the front brakes reinforced with heavy-duty hubs and rotors as well as oversized spindles. Power-assisted steering was also equipped from the factory.
