AL 13 D003 Forged Wheels

AL 13 D003 — Custom Forged Wheel

The AL 13 D003 is part of AL 13's foundational D Series — the design catalog that established the brand's reputation for precision-forged, fully bespoke aluminum wheels engineered and hand-finished at AL 13's Brea, California facility. The D003 is available in 1-piece (monoblock), 2-piece, and 3-piece configurations, meaning the same spoke architecture can be specified across a full range of construction types: from a lightweight monoblock for street-focused builds to a full 3-piece assembly with a separate polished barrel for extreme concave supercar fitments. Like every AL 13 design, the D003 begins from a pressure- and heat-forged aluminum blank — eliminating the micro-porosity present in cast or flow-formed alternatives — and is then high-speed CNC-machined to a run-out standard of 0.007 inch. Every unit is signed off by an AL 13 craftsman before it leaves the Los Angeles facility.

Available Sizes

• Diameters: 13" | 14" | 15" | 16" | 17" | 18" | 19" | 20" | 21" | 22" | 23" | 24"
• Width range: 5J to 14.5J — any step width available on request
• Configurations: 1-piece (monoblock), 2-piece, or 3-piece forged aluminum
• PCD options: 5x112, 5x114.3, 5x120, 5x130, 5x108, 5x150 as standard; center-lock for supercar applications
• Offset (ET): fully bespoke — any ET to clear your brake package and achieve your target stance

Construction advisory: The monoblock (1-piece) configuration offers the lightest overall unsprung weight for a given diameter and width. The 2-piece and 3-piece options allow greater concave depth and enable independent barrel width adjustments after face machining — ideal for wide-body fitments and extreme tuck builds. AL 13 will confirm the optimal construction type for your specific platform during the quotation stage.

Custom sizes available: Because every D003 is built to order, any combination of diameter, width, offset, and PCD is achievable. Contact [email protected] or visit Hodoor's AI Wheel Design Service for a fitment confirmation within 24 hours.

Manufacturing process overview: AL 13 begins each D003 with a round cast bar that is pressure- and heat-forged into a cylindrical blank, compressing the grain structure and eliminating internal voids. A custom-built spin-forging machine extends the rim section radially, aligning the aluminum grain with the principal load paths experienced in service. The blank then moves to high-speed vertical CNC mills where spoke geometry, pocket depth, and surface contour are machined to tolerance. A full lathe pass on both front and rear faces achieves the final profile and concavity before hand-finishing begins. The result is a wheel with measurably superior tensile strength and fatigue resistance compared to cast or flow-formed alternatives of the same weight.

AERO-109R Finish Option

The AL 13 D003 is available in the AERO-109R configuration — a deep aerodynamic rim profile designed to reduce drag coefficient across the wheel arch. The 109R designation refers to the rim depth and inner barrel geometry optimised for high-speed aerodynamic performance, originally developed for European endurance racing. In the AERO-109R configuration, the D003 face design is retained while the inner barrel adopts the deep-dish 109R profile, creating a distinctive wheel-in-wheel visual effect when viewed from the front quarter.

• AERO-109R available in 1-piece, 2-piece, and 3-piece configurations
• Compatible with all AL 13 transparent and solid finish options
• Most commonly specified in 20"–24" diameters for maximum aerodynamic benefit
• Enquire at [email protected] for AERO-109R availability on the D003 design

Finish & Color Options

• Transparent finishes: Carbon Red, Combustion Blue, Cali Gold, Liquid Bronze, Champion Bronze, Clear, Shadow Silver, Shadow Grey, Shadow Black
• Base surface treatments: Gloss Brushed | Gloss Polished | Gloss Stone | Matte Brushed | Matte Polished | Matte Stone
• Solid opaque finishes: Custom RAL, Pantone, or OEM codes in Gloss, Satin, or Texture
• Premium configurations: Two-tone face/barrel, polished lip / matte face, colour-matched to factory paint or wrap code
• 109RD finish variant: A dedicated dark-tinted transparent finish in the AERO-109R configuration — the 109RD provides a smoked mirror-finish over the forged grain, exclusive to the D Series and R Series

AL 13's finish partners in Brisbane, Tokyo, and Hamburg produce the transparent and specialty coatings that define the brand's aesthetic. Colour sample chips and digital mock-up images are provided before production begins on any custom specification.

Frequently Asked Questions

What is the AL 13 D003?
The D003 is a custom forged aluminum wheel from AL 13's foundational D Series, manufactured at AL 13's Brea, California facility from 6061-T6 aerospace-grade aluminum. It is available in 1-piece (monoblock), 2-piece, and 3-piece configurations — all built to order with your exact PCD, offset, width, and finish.

What is the difference between the 1-piece, 2-piece, and 3-piece D003?
The 1-piece (monoblock) is machined from a single forged blank — lightest weight and structurally stiffest for a given size. The 2-piece and 3-piece versions separate the face from the barrel sections, allowing greater concave depth, offset adjustment range, and the ability to mix finishes (for example, a matte face with a polished barrel).

What cars does the D003 fit?
Any modern performance or luxury platform — Porsche, Lamborghini, Ferrari, McLaren, Audi, Mercedes-AMG, BMW M, Bentley, Rolls-Royce, and more. Every set is manufactured to your specific PCD, offset, and brake clearance requirements.

What sizes are available?
Diameters 13" to 24" and widths 5J to 14.5J in any combination. The D Series is most frequently ordered in 19"–24" for performance and luxury fitments.

What is the AERO-109R finish option for the D003?
AERO-109R pairs the D003 face design with AL 13's deep aerodynamic 109R inner barrel — a high rim-depth profile that reduces drag. Available in 1-piece, 2-piece, and 3-piece constructions, with all standard AL 13 colour options. The 109RD dark-tinted transparent finish is exclusive to D and R Series models in the 109R configuration.

How long does delivery take?
Lead time is confirmed at order, as every D003 is forged and finished to specification. Worldwide shipping typically adds 3–10 business days after production. Pre-shipping photos are provided before crating and dispatch.

Wheel Care

• Clean with a pH-neutral wheel cleaner and a soft microfiber or natural-hair brush. Acid and alkaline products etch the brushed, polished, and transparent finishes used on AL 13 wheels.
• Rinse with cool water before applying any cleaning product; avoid spraying onto hot brake rotors or hot wheel surfaces.
• Apply a wheel sealant or SiO2 ceramic coating every 3–4 months to guard against brake-dust iron etching and UV colour degradation.
• Torque wheel bolts to your car manufacturer's specification and re-check after the first 50–100 km of driving following any wheel change.
• For 2-piece and 3-piece configurations, inspect barrel bolts annually and re-torque if required — consult an authorised wheel specialist.
• Inspect for kerb-impact damage regularly — forged aluminum is highly impact-resistant, but any kerb strike should be assessed by a wheel specialist before further high-speed use.
