H&R 31005-2 Sport Cup Kit - Spring & Shock Suspension Package

The H&R 31005-2 Sport Cup Kit is a precision-engineered, application-specific spring and shock absorber package delivering aggressive lowering, improved handling, and a refined street ride. Developed from over 25 years of suspension engineering expertise, this kit goes well beyond generic "matched" spring-and-shock combinations to deliver a truly cohesive performance suspension system.

H&R Sport Cup Kits feature more than 2.0 inches of lowering — approximately 2.1 inches in front and 1.7 inches in the rear — giving your vehicle a commanding low-stance look without sacrificing everyday drivability. Each component is designed and calibrated together so the springs and shocks work in perfect harmony, eliminating the guesswork and performance compromises that come with mixing off-the-shelf parts.

Key Features:

• Application-specific spring and shock system engineered as a complete package
• Approximately 2.0+ inches of average ride height reduction (front ~2.1", rear ~1.7")
• Progressive spring rate design for compliance over small bumps with increased stiffness under load
• Springs approximately 50% stiffer than stock for precise, confident handling
• Lower center of gravity improves cornering stability and overall vehicle dynamics
• H&R 54SiCr6 special spring steel construction with shot-peening for over 200% increased spring life
• Shocks sourced from OEM-experienced manufacturers with motorsport pedigree
• Designed and manufactured in H&R's ISO-certified facility in Germany
• Retains compatibility with stock strut and shock mounts

The Sport Cup Kit builds on all the attributes of the Touring Cup Kit, adding even greater lowering for the performance enthusiast who wants a little more aggression from their suspension setup. Professional installation is recommended, and a full suspension alignment is required after fitment. Front camber plates are also recommended due to the increased front negative camber produced by the lowering.
