Need documentation for your wheel?

3SDM is a British wheel manufacturer that bridges the gap between street style and motorsport function — a position that very few alloy wheel brands occupy with credibility in both directions. Operating out of the UK, 3SDM has built a global following through a consistent design language: multi-spoke profiles with deep concave architecture, available in both cast and forged construction, that look equally at home on a modified hatchback and a racing circuit.
Hodoor sources 3SDM wheels through verified supplier channels and confirms fitment, finish and delivery before quoting.
