Modulare D15 2-Piece Forged Wheels
Modulare D15 2-Piece Forged Wheels
The Modulare D15 is a two-piece forged wheel from the D series — Modulare's dedicated two-piece programme combining a forged aluminium face with a precision-machined outer barrel, joined with aerospace-grade hardware. Produced in the USA from 6061-T6 billet, the D15 offers a compelling balance of customisation flexibility, concave depth, and structural performance that goes well beyond what cast or flow-formed wheels can achieve.
Available Sizes — Modulare D15
- Diameters: 18" | 19" | 20" | 21" | 22" | 23" | 24"
- Widths: 7.5J – 14.5J (barrel adjustable at assembly)

Need a Different Size?
The two-piece construction of the D15 allows barrel width to be set independently of the face, making non-standard widths and offsets straightforward to configure. If your build requires something outside the standard range, our fitment specialists will help. We also offer an AI Wheel Design Service if you want a custom spoke pattern or finish concept designed before production begins.

Finish Options
The Modulare D15 supports independent finishing of the face and barrel. Standard options include gloss black, satin black, gunmetal, and brushed silver. Premium finishes extend to polished face, two-tone machined lip, candy colours, and full RAL or OEM paint-code matching. Hardware can be specified in raw stainless, anodised black, or titanium. Contact Hodoor World for the full Modulare finish chart.
Separating the face and barrel finishes is a popular choice for the D15. Common configurations include: a gloss black face paired with a high-polish machined outer barrel for a classic two-tone look; a satin anthracite face with brushed silver inner barrel for a understated GT aesthetic; and a colour-matched face (BMW or Porsche body code) with a natural brushed barrel for a factory-plus appearance. Premium candy or chrome finishes carry a longer lead time — confirm availability when ordering.
Manufacturing and Quality Assurance
The Modulare D15 face is produced from a 6061-T6 forged blank machined on a multi-axis CNC centre. The barrel is precision-formed and lathe-turned to the specified width and depth, then matched to the face during fitment verification. Face and barrel are surface-treated independently in Modulare's in-house finishing facility, then assembled using aerospace-grade hardware torqued to a defined specification. Aircraft-grade silicone is applied at the mating face before the assembly is torqued to ensure a hermetic, rattle-free joint.
Every D15 set undergoes final inspection to JWL/VIA criteria before dispatch. This includes radial and lateral runout measurement at the bead seat, hub bore concentricity check, and visual inspection of spoke and lip surfaces under controlled lighting. A dimensional data card and assembly torque record are retained on file for each wheel serial number. Warranty claims are processed by serial number — always record your serial numbers after fitting.
Vehicle Fitment Guide
The Modulare D15 two-piece suits a wide range of performance and luxury vehicles. Typical applications include BMW M3/M4/M5 (5×112), Mercedes-AMG GT and E63 (5×112), Audi RS5/RS6 (5×112), Porsche 718/911 (5×130), Ford Mustang (5×114.3), and Chevrolet Camaro/Corvette (5×120). The two-piece design is particularly well-suited to wide-body builds where aggressive offset or step-lip configurations are required.
For staggered fitments (wider rear than front), the D15's two-piece assembly makes it straightforward to produce the same face design in different barrel depths for front and rear axles — an important advantage over monoblock wheels, which require separate machining programmes for different offsets. Provide your front and rear offset targets when ordering, and we will configure each set accordingly.
Other Bolt Patterns Available
Modulare can produce the D15 in any standard or custom bolt pattern — including 5×108, 5×120, 5×127, 5×130, and 6×139.7. Minimum quantities may apply for non-standard PCD configurations. Contact our fitment team with your vehicle details for confirmation.

Frequently Asked Questions
Are Modulare D series wheels tested to a safety standard?
Yes. All Modulare two-piece forged wheels are engineered to meet JWL/VIA load and impact requirements. TÜV certification is available on request for specific diameter and width configurations.
Can the barrel be swapped later to change the offset?
Two-piece wheels can be disassembled by a qualified technician, but this is not a routine service. If you anticipate needing a different offset for a future vehicle, consult us at the time of order — we can often supply a second barrel option.
What sealant is used at the face-to-barrel joint?
Modulare uses aerospace-grade silicone sealant at all assembly joints. This prevents moisture ingress and maintains a pressure-tight seal under track and road conditions.
How do I care for the D15's finish?
Use a pH-neutral wheel cleaner and soft cloth. Avoid abrasive pads, alkaline cleaners, and high-pressure steam at the joint line. For polished surfaces, apply a metal sealant every 3–4 months.
What is included in the box?
Each Modulare D15 set includes the wheels, centre caps, torque sheet, and assembly certificate. Wheel bolts or lug nuts can be added — please specify your vehicle at the time of order.
Are step-lip barrels available for the D15?
Yes. A step-lip configuration (where the outer lip is machined with a visible step or flange) is available on most D series two-piece wheels. This adds a distinctive visual depth when viewed from the side of the vehicle. Specify your preferred step-lip depth in the order notes, and our production team will confirm feasibility for your chosen diameter.
Can I specify different face and barrel finishes independently?
Yes. The two-piece format means the face and barrel are finished separately before assembly — allowing completely different colours, textures, or treatment methods on each component. The most popular split is a colour-matched or gloss face with a polished or brushed barrel. Specify both choices clearly in your order, or contact us for finish sample imagery.
How should I torque the hardware on my D15?
The assembly torque specification is supplied with every D15 set on the included torque data card. As a general guide, Modulare two-piece hardware is typically torqued to 45–55 Nm depending on bolt size, using the supplied thread-locking compound. Do not use pneumatic tools on the assembly bolts — a calibrated torque wrench and a star tightening sequence is required.

Wheel Care and Maintenance
Two-piece forged wheels should have their hardware torque checked annually and after any track use. Clean with a pH-neutral wheel cleaner; avoid high-pressure jets aimed at the face-to-barrel joint. Polished or brushed finishes benefit from a dedicated metal sealant applied every 3–4 months. Inspect spoke roots and the bead seat area annually for road damage or stress marks.
