3SDM 1.55

3SDM 1.55 - Forged Monoblock Street Wheel with Balanced Face Profile

Versatile 1PC Forged Design from 3SDM's British Manufacturing Programme

3SDM 1.55 is a forged monoblock wheel from 3SDM's 1PC Forged range, built to order at their UK facility. The 1.55 offers a balanced aesthetic between flat and concave profiles, making it adaptable for a broad set of street and modified builds where visual proportions are equally important as performance credentials.

3SDM 1.55 Design & Engineering: Balanced Face Profile Forged Monoblock

Machined from a single forged billet, the 1.55 offers face geometry that works across multiple applications from flush fitment to stepped deep-dish builds. The wheel is CNC-machined throughout with the 3SDM logo featured as standard, and optional back pad pocketing provides weight reduction with authenticity markings. FEA analysis is applied with 3SDM's proprietary loading scenarios to ensure consistent structural performance across all profile configurations.
