Street-Oriented Suspension Performance
The Maximum Motorsports Sport Box combines suspension components selected to improve street handling without sacrificing ride comfort. Eibach Pro-Kit springs lower the Mustang, while the matching Koni STR.T struts and shocks provide enhanced suspension performance and good ride quality.
Maximum Motorsports caster/camber plates allow the front alignment to be adjusted within specification. The included urethane spring isolators replace aging factory rubber components during spring installation, while the shorter pinion snubber increases available rear suspension travel.
The Panhard bar improves cornering grip and stability by providing more precise rear axle location. Full-length subframe connectors, the strut tower brace, and the 4-point K-member brace increase chassis rigidity, improving both handling and ride quality.
Urethane steering rack bushings reduce unwanted bushing movement, resulting in improved steering response.
