H&R 28999-1 Sport Lowering Springs Set

H&R 28999-1 Sport Springs are a direct-replacement lowering spring kit engineered to improve handling performance and stance without sacrificing everyday ride comfort. Manufactured at H&R's ISO 9001 certified facility in Germany, these sport springs are built to the same exacting standards that have made H&R the number one choice for suspension upgrades worldwide.

Constructed from a proprietary 54SiCr6 high-chromium silicon spring steel rated at 290,000 psi tensile strength, each spring is shot-peened to extend service life by more than 200% over conventional springs. The result is a spring set that will not set, sag, or lose its calibrated rate over time.

Key Features:

• Lowers ride height 1.5–2.0 inches on average for a sportier, more aggressive stance
• Progressive spring rate design delivers a compliant ride during daily driving and increased firmness under hard cornering
• Reduces body roll by lowering the vehicle's center of gravity for improved handling response
• Minimizes fender well gap for a cleaner, more streamlined appearance
• Shot-peened 54SiCr6 spring steel construction for unrivaled tensile strength and long-term durability
• Engineered and manufactured in Germany at an ISO 9001 certified facility
• Direct OEM replacement — no modifications required
• Sold as a complete front and rear set

H&R Sport Springs are the ideal first suspension upgrade for street-driven vehicles, delivering a balance of improved handling dynamics and a comfortable daily ride that coilover systems often can't match at this price point.
