The 1.56 is designed to highlight 3SDM's custom colour and profile programme - built for applications where both spoke geometry and finish colour are central to the final aesthetic of the build.

The 1.56 is forged and CNC-machined from a single aluminium billet, allowing profile flexibility across flat, concave, and extra concave face configurations. 3SDM's FEA development programme validates structural strength to international certification standards regardless of the profile chosen. Hardware options include Chrome, Black, Gold, and Neo Chrome, with Titanium and painted hardware available as upgrades. Custom logos and caps are available on white label wheel orders.

About 3SDM

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.
