H&R 28802-1 is a vehicle specific lowering spring kit for selected BMW F80 M3, F82 M4 Coupe, and F87 M2 CS applications.

What is included

One H&R 28802-1 spring kit as currently packaged by the manufacturer. H&R’s public application listing does not itemize every supplied component, and its product photography may be representative. Do not assume that mounts, pads, bump stops, dust boots, or fasteners are included unless the paperwork supplied with the kit states otherwise.

Installation and supporting service

Installation must be performed by a qualified professional suspension mechanic. Record ride height from wheel center to fender before and after installation. Inspect the mounts, pads, bump stops, dust boots, spring seats, and fasteners, and replace any component that is not in like new condition.

H&R’s current January 2026 general technical sheet does not list part 28802-1 among the spring kits requiring factory bump stop trimming. Review all product specific paperwork supplied with the kit before installation, as that paperwork controls. Torque fasteners to current BMW specifications, verify Adaptive M Suspension operation when equipped, check wheel and tire clearance, and complete a four wheel alignment after the ride height change.

Warranty

H&R’s current written warranty covers suspension springs for the original retail purchaser for the duration of that purchaser’s ownership of the vehicle, unless the product is discontinued, in which case coverage ends at discontinuance. Coatings are excluded. Coverage requires the correct listed vehicle application and proper installation by a qualified licensed mechanic. Eligibility, exclusions, documentation, and claim handling are governed by H&R’s current written warranty terms.
