Product Description

The H&R 51650-77 Super Sport Lowering Springs are high-performance suspension springs designed for **1979-1993 Ford Mustang V8** models in rear-wheel-drive configuration, including the 1993 SVT Cobra and SVT Cobra R variants. These Super Sport springs feature a progressive spring design that lowers the vehicle's ride height - approximately **1.5 inches in the front** and **1.0 inch in the rear** - to bring the center of gravity closer to the pavement. This reduction in ride height improves cornering stability, reduces body roll, and gives the Mustang a more aggressive stance with a sharper wheel-to-fender fitment compared to stock springs.

Built in Germany from high-strength 54SiCr6 spring steel with a shot-peened finish for strength and fatigue resistance, these Super Sport springs provide enhanced handling and a sporty look while maintaining a balanced ride quality. The direct bolt-in design makes installation straightforward without the need for cutting or special modifications. Pairing these springs with performance shocks or struts is recommended to maximize handling benefits, and a professional alignment after installation helps optimize suspension geometry and tire wear.
