Quantum44 SFF-2 Flow Forged Wheels
Quantum44 SFF-2 Flow Forged Wheels — UK Flow Forged
The Quantum44 SFF-2 is the second model in the Q44 Flow Forged series, representing an evolution of the SFF-1 design concept into a wider size range and an expanded three-finish palette. Where the SFF-1 is offered in 20" only, the SFF-2 extends to 21" for platforms that call for a larger diameter without moving to a full billet forged programme. Each SFF-2 is produced using Quantum44's proprietary spin-forming process — a low-pressure cast blank is flow-formed under controlled roller pressure, thinning the barrel wall and aligning the aluminium grain structure for improved structural integrity. The result is a stronger, lighter wheel than a conventional cast alloy, offered at a price point well below full billet forging. Quantum44 operates from England and ships directly to consumers across Europe and beyond.

Need a Different Size or Bolt Pattern?
The SFF-2 Flow Forged is available beyond the standard catalogue. If your vehicle requires a specific diameter, width, offset, or PCD not listed, contact us at [email protected] and we will confirm availability and lead time. We also offer an AI Wheel Design Service if you want a custom spoke concept or finish visualised before production begins.
Technical Specifications
- Manufacturing process: flow forged monoblock (one-piece)
- Material: A356 aluminium alloy, post-process heat-treated (T6 temper)
- Process detail: Cast blank flow-formed under controlled roller pressure — barrel wall thinned 30–40%, grain structure aligned axially
- Design: a 10-spoke directional layout with slim, evenly-tapered spokes that converge at a low-profile hub cap. The design reads as clean and architectural — precision-engineered rather than decorative.
- Finish — Brushed Titanium: a satin-textured titanium tone achieved through a mechanical brushing process over anodised aluminium. Resistant to fingerprints; depth increases with viewing angle.
- Finish — Gloss Gun Metal: a mid-grey gunmetal coat with high-gloss clear over the entire face and barrel. Stands out strongly against light body colours; equally effective on darker vehicles.
- Finish — Platinum Black: a near-black gloss finish with subtle metallic micro-flake, reducing visual wheel mass. The most aggressive of the three; widely used on sport-performance platforms.
- Hub-centric fit: Yes — bore machined to vehicle hub diameter
- Origin: Manufactured in England, United Kingdom
SFF-2 Flow Forged — Design & Engineering Detail
The spoke count and taper geometry of the SFF-2 are optimised for stiffness without unnecessary material. Each spoke transitions from a narrow hub root to a wider rim shoulder, distributing cornering loads efficiently while maintaining a low-drag aerodynamic profile.
Finish & Colour Options
The SFF-2 Flow Forged is offered in three production finishes. All are standard — no additional lead time or cost for finish selection:
- Brushed Titanium — a satin-textured titanium tone achieved through a mechanical brushing process over anodised aluminium. Resistant to fingerprints; depth increases with viewing angle.
- Gloss Gun Metal — a mid-grey gunmetal coat with high-gloss clear over the entire face and barrel. Stands out strongly against light body colours; equally effective on darker vehicles.
- Platinum Black — a near-black gloss finish with subtle metallic micro-flake, reducing visual wheel mass. The most aggressive of the three; widely used on sport-performance platforms.
Why Flow Forged? The Technical Advantage
Flow forging applies mechanical working to the barrel of an initially cast blank. Hydraulic rollers press against the rotating blank, stretching and thinning the barrel wall while aligning the metal's grain structure along the stress paths the wheel experiences in service. The result: barrel wall thickness can be reduced by 30–40% versus an equivalent cast-only design, directly reducing unsprung rotating mass. Lower unsprung mass improves steering response, braking performance, and ride quality — the same engineering logic that drives adoption of fully forged wheels at the performance end, applied at a more accessible price point. For most road applications, the SFF series represents the optimal balance of engineering, aesthetics, and value.

Correct fitment is the buyer's responsibility — verify PCD, ET, centre bore, and tyre size against your vehicle specification before ordering. Hodoor World offers a pre-order fitment advisory service on request.

Frequently Asked Questions
Is the SFF-2 Flow Forged available in any colour?
The SFF-2 Flow Forged is available in the listed production finishes. Custom finishes are available through the custom manufacturing service.
What PCDs does the SFF-2 Flow Forged support?
Standard PCDs are 5×112, 5×120. Additional bolt patterns are available to order — 5×114.3. 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.
Can I get the SFF-2 in 21" staggered?
Yes — the SFF-2 is available in both 20" and 21" diameter, and staggered front/rear width configurations are supported. A common setup for executive saloons is 21×9.5 front / 21×10.5 rear. Select front and rear axle specifications separately at checkout.
What is the difference between SFF-2 and SFF-1?
The SFF-2 adds 21" sizing, a third PCD option (5×114.3 to order), and a more contemporary three-finish palette (Brushed Titanium, Gloss Gun Metal, Platinum Black) versus the SFF-1's two original finishes (Quartz Silver, Diamond Graphite). The core manufacturing process — flow forming — is the same for both. The SFF-2 also features a higher spoke count and a tighter, more structured visual profile.
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
Flow-formed wheels require regular cleaning to preserve the finish. Rinse with clean water after driving in wet or road-salt conditions before contamination bonds to the surface. Use a pH-neutral wheel cleaner and a soft non-abrasive microfibre mitt — avoid stiff brushes on machined faces. Apply a wheel-specific sealant or wax every 3–4 months. Check valve cores and torque wheel nuts to the vehicle manufacturer's specification after fitment and again after the first 50 km.
