305 Forged UF121 Wheels
305 Forged UF121 — Precision Engineering from Miami
The 305 Forged UF121 is built around a structural geometry that very few monoblock forgings attempt: each of the five primary spokes divides near the wheel face into a twin-tine formation. The split occurs at roughly 60% of the spoke radius, meaning the tines carry load across a significant portion of the barrel approach — this is not a cosmetic fork at the rim edge but a genuine structural bifurcation with real machining depth.
Each tine pair is separated by a pocket running approximately 18mm deep at the spoke centerline. The pocket floor is machined to a coarser mill texture while the spoke surface carries a fine brush — a deliberate two-texture approach that maximises light contrast within a single spoke element. Outer spoke edges carry a chamfered bevel that catches specular highlights on polished or diamond-cut variants.
The non-directional layout means staggered sets run without position restrictions. The UF121 performs at both extremes: BMW M-series track builds where spoke geometry is secondary to structural integrity, and Lamborghini Urus street fitments where visual complexity at 22" carries the aesthetic weight of the entire rear arch.

Design Language & Engineering: UF121
The UF121 face begins at a compact hub pocket machined to a shallow concave, then fans outward through five primary spoke bodies before each splits into the signature double inner tine. The split occurs at approximately 60% of the spoke radius, distributing lateral load across two narrower sections rather than one wide member. Each tine is independently CNC-profiled with sharp pocket-wall intersections that no cast process can replicate.
The inter-spoke geometry creates shadow bands that shift continuously with viewing angle — what reads as a narrow slot from directly ahead opens to a wide pocket at a 45-degree approach. This dynamic quality makes the UF121 one of the few 5-spoke designs that maintains visual interest at any observer position, whether the vehicle is stationary or in motion at speed.
Recommended Finishes for the UF121
Gloss Gunmetal with Diamond-Cut Tine Faces: The two-texture spoke approach of the UF121 is best amplified by machining the inner tine faces to a diamond-cut finish while leaving the spoke bodies in gloss gunmetal. The contrast between silver-bright tines and dark spoke bodies creates depth that reads at normal viewing distances, not only in close-up photography.
Satin Black with Polished Barrel: For builds prioritising stealth, a full satin black face with a polished natural aluminum barrel ring creates a mono-colour face interrupted only by the barrel highlight. This works particularly well on darker vehicle colours where an all-dark wheel would disappear rather than complement the body.
Brushed Titanium PVD: The UF121 responds well to titanium PVD because the multiple spoke surfaces each pick up the coating at slightly different orientations, giving the wheel a multi-tonal quality rather than a flat metallic look. Recommended on vehicles with M Carbon or Forged Carbon exterior trim.

Frequently Asked Questions
What makes the UF121 different from other UF-series wheels?
five-spoke Y-split layout with double inner tines — each primary spoke divides near the wheel face into a twin-tine fork, producing ten visible spoke elements without the mass of a 10-spoke casting.
Is the UF121 directional?
The UF121 is a non-directional design — the same wheel serves both sides without mirror pairing.
What vehicles does the UF121 fit best?
The UF121's 5-spoke design works well across a wide range of performance and luxury platforms. Popular fitments include 20×9.5 ET35 for BMW M3/M4 and 21×10.5 ET38 for Porsche Cayenne. As a custom build-to-order wheel, it adapts to any vehicle — contact us for exact fitment advice.
What sizes are available?
Diameters 13"–24", widths 8.0J–13.5J, any offset and PCD. Hub bore is custom-machined hub-centric — no spacers or adapters needed.
How long does production take?
4–8 weeks from confirmed order and deposit. Rush production may be available — ask at [email protected].
Can I see a finish sample before ordering?
Yes — 305 Forged provides finish samples prior to production. Specify your preferred finish at enquiry and a sample is arranged before the order is confirmed.

Wheel Care — 1-Piece Monoblock Forged
Forged aluminum wheels require minimal maintenance but benefit from regular attention to preserve the finish:
- Clean with pH-neutral wheel cleaner and soft microfibre — avoid acid-based or alkaline products
- Rinse thoroughly after motorway driving in winter (road salt accelerates surface oxidation)
- Inspect for kerb marks seasonally — minor surface scratches can be polished out; deeper marks should be repaired before moisture ingress
- Re-torque wheel bolts to spec after the first 50–100 km following fitment
- Store unmounted wheels vertically on padded pegs — never stack horizontally (face distortion risk)
