3SDM 1.01-R Forged BTO Wheels

3SDM 1.01-R — One-Piece Forged. Built to Your Specification.

The 3SDM 1.01-R represents the brand's most technically accomplished single-piece construction: a fully bespoke build-to-order forged wheel produced from a solid 6082-T6 aluminium billet in 3SDM's UK facility. Where the forged range trades on design innovation within the constraints of forging, the 1.01-R is unrestricted by any mould geometry — every dimension, every curve, every surface angle is machined from the billet to the customer's exact specification. This is not a wheel with a catalogue of options within pre-set parameters; it is a wheel designed in collaboration with the customer and then machined from a block of solid material.

The structural advantage of a 1-piece forged construction over a forged or flow-formed alternative is not merely a matter of material strength — though 6082-T6 aluminium delivers a tensile strength approximately 40% higher than equivalent standard aluminium forgings at comparable sections. The key advantage is weight efficiency: because the billet can be machined to precisely the wall thickness required to meet the structural load case calculated by FEA (Finite Element Analysis), no excess material is retained. The 1.01-R carries only the material it needs — a design philosophy that produces wheels measurably lighter than forged alternatives in equivalent dimensions while maintaining or exceeding structural safety margins.

Available across a 15"–20" diameter range with essentially unlimited width and offset combinations — 3SDM has previously machined 1.01-R wheels from 200 kg billets for specifications that conventional production could not achieve — the 1.01-R is the appropriate choice for racing, trackday, high-performance road, and prestige-build applications where the engineering quality of the wheel must match the investment quality of the vehicle and build programme.

3SDM 1.01-R — Available Sizes

All dimensions are produced to customer specification — widths and offsets beyond the ranges shown are achievable on request.

Need a Different Size?

3SDM's UK manufacturing base is engineered for flexibility. As a fully build-to-order product, the 1.01-R has no hard size limits — any diameter, width, offset, or PCD achievable on a CNC lathe can be produced. If your build requires a diameter, width, or offset outside the standard 3SDM 1.01-R sizing matrix, Hodoor World's bespoke ordering service can accommodate virtually any configuration.

Contact the Hodoor World team at [email protected] to discuss your exact specification with a fitment expert. No dimension is beyond consideration — 3SDM has historically machined wheels from 200 kg solid billets of 6082-T6 aluminium to achieve builds that defy conventional catalogue limits. We also offer an AI Wheel Design Service for enthusiasts who want a fully custom spoke configuration developed specifically for their vehicle and vision.

3SDM 1.01-R — Frequently Asked Questions

What does 'build-to-order' mean for the 1.01-R?

Every 1.01-R is manufactured specifically for the customer's confirmed specification — diameter, width, offset, PCD, face design, finish. The process starts with a specification consultation, followed by CAD design, FEA verification, CNC machining from a 6082-T6 billet, finishing, and quality inspection. Lead time is typically 8–16 weeks.

Why is 6082-T6 superior to forged aluminium standard alloy?

Standard aluminium alloy is optimised for production moulding — it flows well in liquid form but contains elements that reduce mechanical properties versus wrought alloys. 6082-T6 is a structural wrought aluminium alloy with tensile strength ~310 MPa versus forged aluminium's ~230 MPa. For equivalent wall sections, the forged 6082-T6 supports greater loads — or can be machined thinner for the same load, achieving weight savings.

What is FEA and how does it benefit the 1.01-R?

FEA — Finite Element Analysis — simulates how a complex 3D object deforms under defined stress conditions. For the 1.01-R, FEA verifies that spoke geometry, wall thicknesses, and face depth distribute load safely. FEA-optimised geometry means no material is wasted on sections that carry minimal load, and no section is under-designed — resulting in the lightest possible wheel that still meets structural requirements.

What finishes can be applied?

As a bespoke product, the 1.01-R is not limited to standard finish options. 3SDM's capabilities include Silver Cut, Matt Black, Gloss Black, Polished, custom powder coating in any RAL colour, anodising, chrome, and PVD. Discuss finish requirements with Hodoor World at time of specification.

Can the 1.01-R be homologated for motorsport?

3SDM can provide structural test certificates, FEA reports, and material certification documentation. Many organising bodies accept this documentation. For classes requiring specific stamps (VIA/JWL-TS), discuss regulation requirements with Hodoor World before specification.

What is the minimum order quantity?

There is no minimum. Single wheels, pairs, and complete sets of four are all accommodated. For race team volume requirements, pricing may be discussed at specification stage.

3SDM 1.01-R Wheel Care Guide

Regular maintenance preserves finish quality and structural performance. Following these guidelines will keep your 3SDM 1.01-R in showroom condition.

• Cleaning Frequency: Wash at every car wash session. Brake dust is corrosive and attacks lacquer if allowed to bond over heat cycles.
• Approved Cleaners: pH-neutral, alloy-safe cleaners only. No acid-based iron fallout products on Silver Cut or polished sections.
• Technique: Soft-bristle brush between spokes; microfibre cloth on face and barrel. No wire brushes or abrasive pads.
• Polished Elements: Apply metal polish every 3–6 months, followed by non-abrasive wax sealant, on any mirror sections.
• Kerb Damage: Minor scuffs — colour-matched touch-up lacquer. Deep gouges into bare alloy must be professionally repaired promptly.
• Winter Roads: Increase cleaning to weekly on salted roads. Apply an alloy-safe sealant before winter.
• Torque Settings: Re-torque wheel bolts (typically 110–130 Nm) after the first 50 km following any wheel change.
