3SDM 1.10-R Forged BTO Wheels
3SDM 1.10-R — Forged for the Track. Built for Your Build.
The 3SDM 1.10-R is the trackday and clubman competition variant of the brand's 1-piece build-to-order forged programme — engineered with an explicit performance-first mandate rather than the road-use balance of the 1.01-R. Where the 1.01-R's BTO specification encompasses road, prestige, and motorsport applications, the 1.10-R is optimised specifically for the weight and structural efficiency priorities of track and race use. Spoke geometry, hub pocket design, and centre section wall thicknesses are calibrated to achieve the minimum weight that passes the structural load case for the vehicle's track-use application.
The 1.10-R's 6082-T6 aluminium billet construction is identical in material to the 1.01-R — the distinction lies in the geometric choices made during the FEA optimisation stage. On a road wheel, conservatism is built into structural margins to accommodate unpredictable impact events (kerbs, potholes). On a track wheel, the load case is more controlled — the surface is smooth, speeds are documented, and the operator is experienced — allowing FEA to be run against a more precisely defined envelope and section sizes to be reduced accordingly. The 1.10-R exploits this distinction to achieve wheel weights that a conservative road specification would not permit.
Available from 15" to 20" in any width and offset combination, the 3SDM 1.10-R serves circuit racing, hillclimb, sprint, trackday, and time attack builds at any level from regional club competition to professional series. Its build-to-order nature means it can be specified to any class regulation, any homologated dimension, and any finish requirement — from bare machined alloy for minimum weight to any colour or surface treatment the customer specifies.

All dimensions are produced to customer specification. The 1.10-R has no hard dimensional limits — every wheel is engineered to the specific application.
Need a Different Size?
3SDM's UK manufacturing base is engineered for flexibility. The 1.10-R can accommodate any diameter and width required for class-specific motorsport regulations. If your build requires a diameter, width, or offset outside the standard 3SDM 1.10-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 1.10-R — Frequently Asked Questions
How does the 1.10-R differ from the 1.01-R?
Both are 1-piece BTO forged wheels from 6082-T6, machined at 3SDM's UK facility. The 1.01-R uses conservative structural margins for road and prestige use, accounting for unpredictable road loads. The 1.10-R uses tighter FEA margins appropriate for controlled track environments — resulting in lighter section sizes and lower finished weight for comparable structural integrity under competition conditions.
Can the 1.10-R be homologated for competitive motorsport?
3SDM can provide FEA reports, structural test certificates, and material certification. Many organising bodies accept this documentation. For classes with specific homologation requirements (FIA, VIA/JWL-TS stamps), discuss regulation requirements before specification.
What is the lightest configuration available?
A 15" × 6J with minimal spoke geometry in bare machined alloy is the lightest achievable configuration — typically 4.5–6.5 kg. In 18" × 9J competition specification, weights of 6.5–8 kg are achievable. The 1.10-R is engineered to achieve the minimum weight for your confirmed specification.
Is the bare machined alloy finish structural or cosmetic?
Bare machined alloy removes the weight of primer, powder coat, and lacquer layers (nominally 100–300 g per wheel). It is appropriate for competition use where appearance is secondary to weight. A standard alloy sealant can be applied to slow surface oxidation without adding significant weight.
What is the typical lead time for a competition set?
Standard sets of four wheels in a single specification typically take 8–14 weeks from confirmation and deposit. Complex builds with different front/rear specifications or unusual finishes may extend to 16–18 weeks. Racing season scheduling should be discussed as early as possible.
Can I arrange a facility visit to discuss my specification?
Visits to 3SDM's UK manufacturing facility can be arranged for serious enquiries. Contact Hodoor World at [email protected] or WhatsApp +44 7488 818747 to discuss specification and arrange a visit where appropriate.

3SDM 1.10-R Wheel Care Guide
Regular maintenance preserves finish quality and structural performance. Following these guidelines will keep your 3SDM 1.10-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.
