Quantum44 ZF-3 Two Piece Forged Wheels

Quantum44 ZF-3 Two Piece Forged Wheels — UK Full Forged

The Quantum44 ZF-3 Two Piece is a two-piece full billet forged wheel — a seven-spoke forged monoblock with a clean, restrained profile suited to executive and GT platforms. The ZF-3 Two Piece separates the forged face from a separately manufactured barrel, enabling deeper concave profiles and rim widths beyond the practical limit of single-piece machining. Quantum44 builds every set to order at its UK facility, specifying diameter, width, offset, PCD, and finish to the customer's exact brief. The ZF-3 carries Quantum44's standard forged specification: 6061-T6 aluminium, multi-axis CNC machining, and structural testing to European load standards.

Technical Specifications

• Manufacturing process: Two Piece
• Material: 6061-T6 aerospace-grade forged aluminium billet
• Machining: Multi-axis CNC — face, spokes, and hub flanges in one programme
• Yield strength: ≥276 MPa (standard for 6061-T6 solution heat-treated and aged)
• Design: a seven-spoke pattern with uniform taper from hub to rim — each spoke is straight in plan view, giving the design a clean, restrained character. The hub cap area is recessed, and the spokes share a consistent chamfered-edge profile.
• Finish: The ZF-3 Two Piece is finished to client specification. Options include gloss or satin painted (any RAL/BS colour), brushed with anodising, polished face with painted barrel, and full polished. Two-piece construction allows independent finishing of face and barrel.
• Hub-centric fit: Yes — bore machined to vehicle hub diameter
• Origin: Manufactured in England, United Kingdom

ZF-3 Two Piece Forged — Design & Engineering Detail

Seven-spoke designs distribute rotational load across more paths than five- or three-spoke alternatives, reducing stress concentration at each spoke root. The ZF-3's straight-spoke geometry minimises bending moments under braking — spokes running radially transfer braking torque more directly than angled designs, reducing the cyclic stress range.

Why Full Billet Forged? The Technical Case

Full billet forging starts with a solid block of 6061-T6 aluminium. Under high press tonnage, the billet is shaped, establishing a grain structure aligned with the finished part's stress paths. Subsequent CNC machining removes material to achieve the final geometry. The result is a wheel with no porosity, no inclusions, and a consistent grain structure — properties that cannot be replicated in cast, semi-cast, or flow-formed processes. Yield strength exceeds 276 MPa, compared to 180–220 MPa in gravity-cast alloys. Billet forging is the manufacturing process used in motorsport, aerospace structural components, and the top tier of the custom wheel industry. The weight reduction vs. cast is real and measurable: a forged 20×10 monoblock typically runs 1.5–2.5 kg lighter than a cast equivalent in the same design, reducing unsprung rotating mass and improving the entire dynamics envelope — steering response, braking stability, ride quality, and acceleration.

ZF-3 Two Piece Design Language

The ZF-3 achieves its character through deliberate restraint. A seven-spoke layout with straight, uniformly tapered spokes — no split, no curve, no taper variation. Each spoke traces a clean radial line from hub to rim, narrowing at a fixed rate that is identical across all seven elements. The hub cap is recessed, creating a small shadow that emphasises the central ring. At the rim shoulder, spokes arrive at consistent widths with no flare or trumpet profile. Seven is not a common spoke count for forged performance wheels — most designs favour five, ten, or twelve. Quantum44's choice of seven disrupts the expected visual rhythm, preventing the eye from completing a predictable pattern too quickly. The odd-prime count means opposite spokes are never precisely aligned, which creates a slightly asymmetric face texture that shifts depending on where rotation has stopped. The ZF-3 sits most naturally on GT cars, luxury saloons, and understated performance builds where the intention is refinement rather than aggression. Its design language is close to what certain German OEM alloy manufacturers were producing in the early 2010s — but executed in a premium material at a scale that OEM tooling would not justify. In two-piece form, the ZF-3 face gains additional aesthetic flexibility: the barrel is manufactured separately, allowing deeper concave profiles and wider reverse lips than single-piece machining permits. The face design remains identical to the Monoblock version, but the two-piece assembly means the barrel offset can be adjusted during the build rather than fixed at manufacturing stage.

ZF-3 Two Piece: Two-Piece Construction Advantages

The ZF-3 Two Piece applies the seven-spoke straight architecture to a two-piece platform, making the ZF-3's restrained aesthetic available at offset and concave specifications that the Monoblock cannot reach. The straight spoke geometry of the ZF-3 is dimensionally straightforward to assemble in two-piece form — the spoke roots terminate in a clean circular flange that mates to the barrel with consistent bolt-circle geometry. Unlike curved or split-spoke designs, the ZF-3's straight spokes produce no parasitic torque on the face-barrel joint under cornering loads, which simplifies the hardware specification and reduces long-term maintenance requirements. The ZF-3 Two Piece is particularly well-suited to staggered axle setups — rear wheels can be specified at significantly different width and offset to fronts, with the face design remaining identical across both axles. Contact Quantum44 via Hodoor with your vehicle's front and rear fitment requirements and we will confirm whether staggered sizing is achievable within the current production capability.

ZF-3 Two Piece Target Platforms

The ZF-3 Two Piece suits staggered high-end platform builds where the restrained spoke design should be maintained across all four corners despite significant front-to-rear size differences. Porsche 911 GT3 in 5x130 with staggered front/rear sizing, Bentley Continental in 5x112 with varying wheel widths front and rear, and Mercedes AMG GT with S or R suffix requiring extreme rear width are ZF-3 Two Piece applications. The two-piece construction enables the rear wheel at 12J to share the same face design as the front wheel at 9J — impossible with monoblock production at this concave profile.

Frequently Asked Questions

Is the ZF-3 Two Piece Forged available in any colour?
Yes — as a full billet forged product, the ZF-3 Two Piece Forged is finished to specification. Any painted, brushed, or polished finish can be specified. Contact [email protected] for details.

What PCDs does the ZF-3 Two Piece Forged support?
Standard PCDs are 5×112, 5×120, 5×114.3, 5×130. Additional bolt patterns are available to order — any PCD — built to order. Contact [email protected] with your vehicle's PCD to confirm.

How do I know what offset to choose?
Offset (ET) determines how far the wheel face sits from the hub mounting face. A correct ET ensures the tyre clears the suspension components and sits flush within the arch. The right ET depends on your vehicle's hub, brake caliper, and suspension geometry. Contact [email protected] with your vehicle details for a recommendation before ordering.

Is the ZF-3 available as a monoblock or two-piece?
Both variants are produced. The ZF-3 Two Piece features a separately constructed barrel, enabling deeper concave profiles and wider rim widths than the monoblock version. Both share the same face design. Order the Monoblock if you prioritise minimum wheel mass or want the single-piece construction for motorsport applications.

What colours are available on the ZF-3 Two Piece?
Any colour — the ZF-3 is finished to specification. Common choices include: Gloss Pearl White, Satin Carbon Grey, Brushed Titanium with clear, Polished face/Gloss Black barrel, Full Polished. Two-piece construction allows contrasting face and barrel finishes. Submit your spec to [email protected] for a quote.

Does Hodoor World offer a fitment advisory service?
Yes. If you are unsure about PCD, ET, width, or tyre sizing for your vehicle, contact us at [email protected] before ordering. We will confirm the correct specification for your platform.

Wheel Care

Full billet forged wheels with a painted or polished finish require regular cleaning to maintain appearance and protect the surface. Rinse after each drive in wet or road-salt conditions. Use a pH-neutral wheel cleaner — acid-based products will attack anodised and polished finishes. Apply a ceramic wheel sealant every 3–4 months to protect the topcoat. For polished wheels, a dedicated metal polish applied monthly will prevent oxidation. Torque wheel nuts to your vehicle manufacturer's specification (typically 110–140 Nm for M14×1.5 fasteners on performance platforms) after fitment and again after 50 km.
