3SDM 1.20

3SDM 1.20 - Angular Spoke Forged Monoblock for the Modern Performance Car

Contemporary Geometry Meets 1PC Forged Precision

The 3SDM 1.20 is a 1PC forged monoblock wheel that brought a sharper, more angular spoke profile to the 3SDM forged range. Its design sits between the heritage compactness of earlier models and the deep-face openness of the brand's more aggressive pieces, offering a versatile face profile that suits a wide range of vehicle styles.

3SDM 1.20 Design Language: Sharp Angles, Refined Surface

The 1.20 uses a Y-spoke pattern where each primary spoke branches into two legs toward the rim, creating a dynamic surface with clean machined edges running their full length. The spoke tops carry a narrow highlight and taper toward the barrel with a gradual concave sweep, giving the face a layered depth without requiring extreme width to achieve the visual effect.

3SDM 1.20 Forged Construction: Billet-to-Wheel Precision

Forged monoblock production means the 1.20's hub, spokes, and barrel are machined from a single piece of densified aluminium. Compared to cast or flow-formed alternatives, the forged billet process produces tighter grain boundaries and higher tensile strength, allowing the same structural performance at reduced mass. Every 1.20 is CNC machined to finished dimensions from that single billet.

3SDM 1.20 Technical Specifications

Construction: Forged monoblock. Material: Forged aluminum alloy. Available in 15" to 20" diameters. Width range: 5J to 14.5J. Manufactured by 3SDM Wheels.

3SDM 1.20 Available Finishes

The 1.20 is offered through the standard 3SDM finishing programme. The Grey finish shown in the product imagery represents one of the mid-tone options available; the full programme extends to Silver Shadow, Satin Black, Gunmetal Grey, Imola Bronze, and additional custom specifications. Two-tone and bespoke paint-matched finishes are available on request.

3SDM 1.20 Vehicle Fitment: Crossovers, Saloons, and Performance Hatches

The 1.20's proportioned spoke structure makes it adaptable across vehicle classes. It has been fitted to compact performance hatchbacks at tighter widths and to executive saloons and large sports cars at the wider end of the available range. The 15" to 20" diameter spread allows the 1.20 to be used on vehicles from the compact end of the market through to larger-platform premium cars.

Any Vehicle, Any Specification

The 3SDM 1.20 can be built to order for any vehicle and any specification — not just the models listed above. Diameter, width, offset, and centre bore are defined at the manufacturing stage. Contact us with your vehicle make, model, and year for a confirmed fitment specification and build quote.
