Like all STI HD Alloy series wheels, the lightweight HD4 comes with a no-hassle Lifetime Structural Warranty, thanks to its unique inner and outer heavy-duty wheel lip reinforcement. The HD4 is both a beauty and a beast, boasting 1000-lb. load ratings for the 14-, 15- and industry-first 17-inch models.
HD4 wheels are available in a striking Gloss Black finish with machined accents, chrome bolts and rivets, and a Hi-Gloss clear coat seal. The newest model in the HD4 line is made with a Matte Black finish.
