What is included

Vehicle-specific H&R Sport Spring kit. Exact spring and hardware counts are not publicly itemized; OE dampers and PASM Sport remain in use.

Required or recommended supporting components

Four-wheel alignment is required. Inspect mounts, bearings, bumpstops, dust boots, spring seats, and fasteners. Confirm front-lift operation plus wheel, tire, brake-duct, and aero clearance.

Installation notes

H&R requires installation by a qualified licensed suspension mechanic. Measure ride height from wheel center to fender before and after installation. Reuse original bumpstops, dust boots, and other OE parts when they are not included; inspect and replace anything that is not in like-new condition. Torque all fasteners to current Porsche factory specifications and double-check the completed installation.

H&R’s current general technical sheet does not list this kit among the applications that require bumpstop trimming; review all product-specific paperwork supplied with the kit before work begins. A four-wheel alignment is required after changing ride height.

Tuning, coding, and calibration

No product-specific coding requirement is published by H&R. Verify front-lift and chassis-system operation and follow Porsche service information for any calibration required after geometry changes.
