H&R 31054-6 Sport Cup Kit - Performance Spring & Shock Suspension Kit

The H&R 31054-6 Sport Cup Kit is a complete, application-specific spring and shock absorber system engineered to deliver a super-low performance stance without sacrificing ride quality. Designed and manufactured in Germany at H&R's ISO-certified facility, this kit represents decades of suspension engineering expertise built into a single, precision-matched package.

Unlike generic "matched" spring and shock bundles, the Sport Cup Kit features springs and shocks that are individually engineered together for the specific chassis — accounting for spring rates, chassis geometry, and suspension travel. This eliminates the guesswork of mixing and matching components and avoids common pitfalls such as under-damping or mismatched spring rates.

Key Features:

• Lowering: Approximately 2.2" front / 1.5" rear drop in ride height
• Progressive spring rate design maintains superior ride comfort over small bumps while stiffening appropriately under hard cornering
• Custom-valved performance shocks precisely matched to the included sport springs
• Lower center of gravity reduces body roll and improves overall handling and steering response
• Stiffer setup compared to the Touring Cup Kit (part number 31054T-6) — ideal for enthusiasts prioritizing performance over comfort
• Compatible with OEM strut and shock mounts; front camber plates recommended due to increased front negative camber
• Includes front and rear springs and shocks
• 100% German-made; backed by H&R's lifetime defect warranty

The Sport Cup Kit steps up from the Touring Cup Kit with additional lowering and a firmer, more sport-focused tune — making it the top choice for performance-oriented drivers who want a precisely calibrated suspension package with an aggressive, track-ready stance that is still fully street-legal and drivable.
