Product Description

H&R 51650-99 Super Race Lowering Springs are a high-performance suspension upgrade built for Ford Mustang generations spanning 1979 to 2004. These race-oriented springs significantly lower the vehicle's ride height - typically around 1.0 to 1.75 inches in the front and 0.75 to 1.25 inches in the rear - reducing the center of gravity and helping improve steering response, cornering control, and weight balance. Designed for enthusiasts seeking a more aggressive stance and enhanced handling on street or track applications, the Super Race springs deliver improved grip and reduced body roll under dynamic driving conditions.

Crafted in Germany from high-strength 54SiCr6 spring steel and engineered with progressive rates, these H&R Super Race Springs pair exceptionally well with performance shocks or struts to maximize suspension performance. This kit includes four springs for front and rear installation and is ideal for Mustang owners who want standout performance and a race-ready look without converting to full coilover systems.
