1221 Wheels 1331 AP2 APEX3.0 Forged Wheels
1221 Wheels 1331 AP2 APEX3.0 — Triple-Branch Geometry in Two-Piece Forged Architecture
The 1331 is defined by its Y-shaped spoke arrangement: three primary arms radiate from the hub, each branching into a secondary split before meeting the barrel lip — thirteen total spokes that divide the face into a uniform geometric grid without sacrificing visual openness. In the AP2 two-piece configuration of 1221's APEX3.0 edition, the 1331 combines this disciplined spoke architecture with the barrel flexibility that only a modular build can offer. Where a monoblock forces you to choose between spoke depth and offset range, the 1331 AP2 decouples them entirely — the face geometry is fixed, and the forged outer barrel is adjusted per order to achieve the exact back-spacing, concave depth, and lip profile your build requires. Built at 1221 Wheels' facility in City of Industry, California, this is the configuration that makes the 1331's structured face accessible across the full range of European and Japanese sport GT applications.

Need a Different Size?
Every 1221 Wheels 1331 AP2 APEX3.0 is produced to order from City of Industry, CA. In the two-piece AP2 configuration, diameter, width, and offset are adjusted independently — the 1331 face tooling does not change regardless of barrel specification, so non-standard widths or offsets carry no premium over standard fitments. Send your vehicle details, arch measurements, and brake system dimensions to [email protected] or reach us via WhatsApp at +44 748 881 8747. We confirm the exact specification directly with the 1221 production schedule before your order is placed. We also offer an AI Wheel Design Service if you want a bespoke spoke pattern or finish concept visualised before production begins.

Finish & Colour Options
The two-piece architecture of the 1331 AP2 APEX3.0 allows the forged face and the forged outer barrel to receive independent finish treatments within a single order. The Y-branch spoke geometry creates a natural visual separation between the face field and the barrel — a contrast finish exploits this geometry directly. A Brushed Gloss Clear face against a Solid Matte Black barrel reads as a designed statement rather than a workshop mod, because both components are machined and coated as separate forgings before assembly. All 34 standard finishes from 1221's catalogue are available for both sections independently. Polished stainless lip inserts are also available for builds that want a bright rim edge against a dark face. Custom RAL treatments can be specified for either section independently.

Vehicle Fitment Guide — Sport GT and Track-Modified Applications
The 1221 Wheels 1331 AP2 APEX3.0 is specified most frequently for sport GT, performance coupé, and track-prepared builds where the Y-branch spoke face provides visual weight reduction from every angle, and the two-piece barrel adjustment allows flush or aggressive fitment without suspension modification. The structured 1331 geometry works particularly well on wide-arch and flared fitments where the spoke pattern fills the arch opening without looking over-detailed at larger diameters.

Other Bolt Patterns — Drilled to Your Exact Application
The 1331 AP2 APEX3.0 is not a catalogued item with a fixed PCD range — every unit is custom-drilled to your vehicle's bolt pattern. Standard patterns covered include 5×112, 5×114.3, 5×120, 5×130, 5×108, and 5×100, but 4×100, 4×108, 5×98, and other patterns can be produced on request. Because the face is drilled as a separate forged component in the two-piece architecture, bolt pattern changes carry no impact on barrel specification. Centre bore is machined to OEM tolerance — no spigot ring required. Contact [email protected] with your PCD, centre bore diameter, and thread pitch for production confirmation.

Frequently Asked Questions
What does the 1331 designation refer to?
The 1331 is a model designation within the 1221 Wheels X-Series that identifies the face design — specifically the Y-branch triple-arm spoke pattern that produces 13 spoke elements at the barrel transition. The number does not correspond to diameter or spoke count directly; it is a 1221-assigned style identifier within the APEX3.0 edition.
How is the Y-branch face different from a conventional split-spoke design?
In the 1331, the three primary arms are forged as continuous structural elements from the hub flange to the barrel junction, with the branch points positioned at a consistent radial distance. This produces uniform stress distribution across the face under lateral and braking loads, which is why the 1331 geometry passes 1221's FEA criteria without adding material to the spoke cross-sections. A conventional split-spoke design typically requires thicker spoke roots to compensate for stress concentration at the junction.
Can I have the face and the barrel in different finishes?
Yes — two-tone finish selection per section is a standard option on all AP2 builds. Any combination from the 34 standard finishes can be specified for the face and barrel independently. Custom RAL colours and polished lip inserts are also available. Specify your combination when you contact us with your fitment data.
Is the 1331 AP2 available for right-hand-drive vehicles?
Yes. 1221 Wheels X-Series wheels are handed — the 1331 AP2 is available in both left-hand and right-hand versions, with the spoke branch direction matched to the wheel's rotation direction on each corner. Specify RHD or LHD when you submit your fitment data and we will confirm the correct orientation for your application.
What is the production lead time?
Approximately 3–6 weeks from order confirmation, depending on finish specification and current production scheduling at 1221 Wheels in City of Industry, CA. Complex two-tone or custom RAL finishes may extend the schedule by 1–2 weeks. Contact us to discuss your timeline if delivery date is critical.
Are 1221 Wheels products JWL or TÜV certified?
1221 Wheels produces to the structural standards validated by its own FEA programme and quality controls at the City of Industry facility. For markets where third-party certification is required for road use, please confirm the applicable standard with us before ordering and we will advise on the available certification options for the 1331 AP2 APEX3.0.

Wheel Care
The 1221 Wheels 1331 AP2 APEX3.0 is finished in 1221's standard high-durability coating, designed to resist road salt, brake dust, and thermal cycling across the full range of ambient conditions. Rinse the wheel with fresh water after each drive in wet or salted conditions. Wash with a pH-neutral wheel cleaner using a soft-bristle brush — avoid alkaline degreasers and abrasive compounds on Brushed Gloss or Brushed Matte finishes. For two-tone builds, apply a non-silicone wheel sealant to the barrel section after each wash to protect the outer surface from kerb debris and stone impact. If the wheels are stored off the vehicle, keep them vertically in a cool, dry environment — avoid stacking face-to-face under any load. Torque bolts to the specification supplied with your order (typically 120–140 Nm for standard applications) and re-verify torque after the first 50 km following fitting.
