H&R 50478 Street Performance Coilover Kit

The H&R 50478 Street Performance Coilover Kit delivers the ideal balance of performance handling and everyday ride comfort, making it a top choice for drivers ranging from daily commuters to dedicated enthusiasts. Each coilover shock is custom-valved to work in harmony with a precision-engineered, progressive-rate spring, resulting in a cohesive and finely tuned suspension system.

Key Features:

• Custom-Valved Shock Absorbers: Each shock is individually calibrated to complement the progressive-rate spring for optimal ride quality and handling response
• Progressive-Rate Springs: Precision-engineered spring rates provide a compliant ride during normal driving while firming up under aggressive cornering and load
• Fully Threaded Shock Body: Allows for adjustable ride height without changing spring preload, enabling precise vehicle stance tuning
• Lowered Center of Gravity: Height adjustability helps redistribute vehicle weight for improved balance, stability, and cornering performance
• Dual-Purpose Design: Engineered to satisfy both comfort-focused daily drivers and performance-oriented tuners

The H&R 50478 coilover kit replaces the factory suspension with a fully integrated system that improves upon OEM geometry while providing measurable gains in handling precision and control. H&R's Street Performance Coilovers are built to exacting German engineering standards, reflecting the brand's decades of motorsport and performance suspension development.
