STI HD4 is available in an industry-first 17x7. This innovative size joins 12x7, 14x7 and 15x7 dimensions in the HD4 lineup. STI is also now unveiling a new tire — the Roctane XS to take advantage of the 17x7 rim size.
STI HD4 debuts in a striking Gloss Black finish with machined accents, topped with a Hi-Gloss clear coat seal. Adding to this wheel’s dynamic personality are chrome bolts and rivets. The final touch is a matching low-profile center cap.
Like all STI HD Alloy series wheels, the lightweight HD4 comes with a no-hassle Lifetime Structural Warranty, thanks to 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 17 inch models.
The new HD4 is obviously a premium wheel, but it does not come at a premium price. As always, STI strives to deliver both performance and value in every product it makes.
