H&R 50457 Street Performance Coilover Kit

The H&R 50457 Street Performance Coilover Kit is a complete, vehicle-specific suspension system engineered to deliver an exceptional balance of ride comfort and performance handling. Designed for street use, this coilover kit replaces your factory springs and shock absorbers with a fully integrated, height-adjustable system built to H&R's exacting German engineering standards.

At the heart of the system is a mono-tube gas shock construction — a significant upgrade over traditional twin-tube dampers. Each shock is precision-tuned in concert with a matched progressive-rate coil spring, engineered from the ground up to work with the shock's specific valving. The result is a suspension system that feels compliant and comfortable under normal driving conditions, yet firms up progressively during spirited cornering and hard braking.

Key Features:

• Mono-tube gas shock absorbers for precise, responsive damping
• Vehicle-specific progressive-rate coil springs matched to shock valving
• Fully threaded shock body with easy-to-adjust spring seats for ride height tuning
• Adjustable lowering range of approximately 1.25" – 1.8" front and 1.0" – 1.75" rear
• Complete coilover system — all matched components included
• Durable corrosion-resistant construction for long service life
• Engineered and manufactured in Germany

H&R Street Performance Coilovers are well-suited for daily drivers and enthusiasts alike — anyone who wants a cleaner stance, reduced body roll, and sharper handling without sacrificing everyday ride quality. The fully threaded shock body and adjustable spring seats make dialing in your preferred ride height straightforward, accommodating varying preferences or seasonal adjustments.
