3SDM 3.71-T2 FR Series 3-Piece Forged Wheels

3SDM 3.71-T2 FR Series 3-Piece Forged Wheels — Fully Modular 3-Piece Forged Construction

The 3SDM 3.71-T2 FR Series is the Type 2 evolution of the 3SDM 3.71 design — a refined iteration of the same multi-spoke architecture, with spoke geometry that builds on the 3.71's strong visual identity while introducing proportional adjustments that improve the wheel's coherence at larger diameters and wider barrel configurations. Like the base 3.71, the 3.71-T2 is assembled at 3SDM's UK facility as a fully modular 3-piece forged build: the spoke face, outer step-lip rim, and inner barrel are each independently forged and CNC-machined before precision assembly with the buyer's chosen hardware. The T2 designation preserves full compatibility with the FR, FX2, and FX3 profile range — the concavity configuration is specified at order time, not constrained by the design variant. Available in diameters from 13 to 24 inches, widths from 5J to 14.5J, and any standard PCD — the 3.71-T2 is manufactured entirely to the buyer's specification with no shelf-inventory compromise.

Recommended fitment notes: 3SDM engineers each set to your car. Submit your make, model, year, brake package, and target stance, and the 3SDM team will confirm the optimal diameter, width, and offset combination. Custom step lips and barrel depths are part of every specification.

Need a different size or bolt pattern? The 3.71-T2 is a fully bespoke build — 3SDM manufacture this model in any size, offset, and PCD on request. We also offer an AI Wheel Design Service if you want a custom concavity profile or spoke finish on the 3.71-T2 platform. Contact us at [email protected] and we will source the right fitment for you.

Engineering advantage: 3SDM's modular FR Series separates the wheel face, inner barrel, and outer rim into three independently manufactured components. This separation allows each piece to be machined to tighter tolerances than a single-piece casting or flow-form — the face is forged to the precise spoke geometry, the barrel is rolled to the exact width, and the rim halves are CNC-profiled to match the chosen step-lip depth. The result is a wheel with measurably better concentricity, lower unsprung mass for a given stiffness target, and a wider range of fitments than any production-run wheel can cover.

• Gloss: Gloss White, Gloss Black, Gloss Gunmetal, Gloss Bronze, Gloss Anthracite, custom RAL/NCS paint codes

• Powder coat and custom match: 3SDM can match any factory OEM paint code, wrap colour, or custom colour reference — sample chips and colour approval photos before production start

All finish work is carried out at the 3SDM facility in the United Kingdom. Every completed set receives a final quality inspection before crating.

3SDM 3.71-T2 FR Series — Configuration Comparison

All three configurations share the same spoke design and PCD options — the profile is chosen at order time. FR is the base configuration suited to street and daily use; FX2 and FX3 deliver progressively deeper concave profiles for stance and show applications.

Frequently Asked Questions

What is the 3SDM 3.71-T2 FR Series?
It is the base flat-face 3-piece modular forged variant of the 3SDM 3.71-T2 design — manufactured from 6061-T6 aerospace-grade forged aluminium at the 3SDM facility in the United Kingdom. The FR Series designation refers to the flat-face base configuration; the same 3.71-T2 spoke pattern is available in FX2 (concave) and FX3 (X-concave) profiles for customers targeting deeper dish or extreme stance applications. Every set is built to the buyer's exact car — PCD, offset, step-lip depth, and hardware finish are all specified at the time of order.

What cars does the 3.71-T2 FR Series fit?
Any modern performance or luxury platform — common fitments include Porsche 911 / Cayenne, Lamborghini Huracán / Aventador, Ferrari 488 / F8 / 812, McLaren 720S / 765LT, Audi RS-series, Mercedes-AMG G 63 / GT, BMW M3 / M4 / M5 / M8, Nissan GT-R, and Rolls-Royce. Every set is built to your exact PCD, offset, and brake clearance — no shelf inventory, no compromise on fitment.

What is the difference between FR, FX2, and FX3?
All three are 3-piece configurations of the same 3.71-T2 spoke design. FR has a flat face — the classic 3-piece look with a clean face plane. FX2 adds a concave bowl to the spoke face — deeper draw toward the centre, suited to stance and show builds. FX3 takes this further with an extreme X-concave profile — the deepest concavity 3SDM offer on this design. The three can be ordered with the same hardware and colour options; the profile is the only structural difference.

Are the 3.71-T2 FR Series wheels certified?
Yes. 3SDM uses FEA (Finite Element Analysis) with proprietary loading scenarios and can certify wheels to JWL VIA, ISO, and TUV standards on request. Certification documentation is supplied with the order — useful for track-day scrutineering and EU type-approval requirements.

How long does it take to receive the wheels?
The 3.71-T2 FR Series is made to order — there is no shelf inventory. Contact us via [email protected] for current production lead times. Worldwide shipping is typically 3–10 business days from despatch, depending on destination.

Can I get the 3.71-T2 in a two-tone or custom colour?
Yes. 3SDM can finish the face and barrel in different colours (two-tone), match factory OEM paint codes, wrap colours, or fully custom RAL/NCS references. Sample chips and colour approval photographs are provided before production commences — no surprises on delivery.

Wheel Care

• Clean with a pH-neutral wheel cleaner and a soft microfibre brush. Avoid alkaline or acid-based products — they can damage brushed, polished, and painted finishes on forged wheels.
• Rinse with cool or tepid water before applying any cleaning product; never apply product directly to hot wheels or brake rotors.
• Apply a dedicated wheel sealant or ceramic coating every 3–4 months to protect against brake-dust etching, UV degradation, and road salt.
• Torque wheel bolts to manufacturer specification using a calibrated torque wrench; re-check after the first 50–100 km following installation.
• Inspect regularly for kerb impact damage — 3-piece forged construction is highly impact-resistant, but any significant strike should be assessed by a wheel specialist before continued use at speed.
• Hardware bolts can be inspected and replaced independently — one of the advantages of 3-piece modular construction.
