21×10 Forged Monoblock Wheels for Audi SQ5 3.0 V6 – Matte Gunmetal Deep-Concave 5-Spoke 5×112

Engineering Notes

XINGTU’s engineers want to highlight three details that define this build.

Wide Five-Spoke Forged Monoblock Design

The 21×10 wheel features five broad spokes extending from a deeply recessed center to the outer rim. The open spaces between the spokes reveal the brake area and emphasize the depth of the concave profile, giving the wheel a clean, substantial appearance without intricate decorative details.

The center, spokes and barrel are CNC-machined from a single forged aluminum blank, forming a continuous monoblock structure without separate bolted joints. The wide spoke sections and sculpted transitions create a balanced arrangement of solid surfaces and open areas across the wheel face.

Each finished wheel weighs 13.6 kg and carries a rated load capacity of 900 kg, combining the wide-wheel configuration with the load specifications of this Audi SQ5 project.

Matte Gunmetal Finish

Matte Gunmetal gives the five-spoke design a subdued metallic appearance, with a low-reflection surface that brings out the contours of the broad spokes and recessed center.

The finish extends across the wheel face, outer rim and barrel, maintaining a consistent color through the flat spoke surfaces and curved transitions. Careful surface preparation and controlled coating application help preserve an even matte appearance, particularly where the spokes meet the deeply concave center.

A protective matte clear coat completes the surface treatment, helping resist moisture, brake dust and everyday cleaning exposure while retaining the finish's restrained metallic character.

Precision Fitment for the Audi SQ5

The wheel measures 21×10 with an ET18 offset, 5×112 bolt pattern and 66.6 mm center bore. Its mounting configuration also features a 15×32×R14 short ball-seat specification.

The ET18 offset and wide barrel establish the wheel's position relative to the mounting surface, while the deep-concave profile defines the appearance of the five-spoke face. Together, these dimensions form the production configuration developed for the Audi SQ5 3.0 V6.

Vehicle compatibility depends on the specific SQ5 configuration, including hub dimensions, mounting hardware, brake clearance, suspension geometry and tire specifications.

From Design to Delivery

• PCD, center bore and ET dimensions inspected
• 15×32×R14 ball-seat profile checked
• Wheel weight verified at 13.6 kg
• Radial and lateral runout inspected
• Five-spoke machining and concave-profile consistency checked
• Matte gunmetal color and sheen inspected under controlled lighting
• Dynamic balancing completed for every wheel

Result

The finished wheel brings together five broad spokes, a pronounced concave center and generous open sections that reveal the brake area. Its clean spoke arrangement gives the 21-inch face a substantial appearance, while the recessed hub creates a clear sense of depth.

Matte Gunmetal provides a consistent metallic tone across the wheel, highlighting the curved spoke transitions without the strong reflections of a gloss finish. The completed 21×10 forged monoblock wheel retains its ET18 configuration, with a finished weight of 13.6 kg and a rated load capacity of 900 kg per wheel.

Wheel Dimensions & Mounting Specifications

The wheel features a 21×10 size, ET18 offset, 5×112 bolt pattern and 66.6 mm center bore. The 15×32×R14 short ball-seat specification completes the mounting geometry. These dimensions apply to the featured Audi SQ5 configuration, with final fitment dependent on the vehicle's hub, brakes, suspension and tire setup.

One-Piece Forged Aluminum Construction

The forged monoblock structure integrates the hub, five broad spokes and barrel into a single aluminum body. Large openings between the spokes reveal the brake area, while the concave center creates a distinctive wheel-face profile. Each wheel weighs 13.6 kg and carries a rated load capacity of 900 kg.

Matte Gunmetal Surface Finish

A uniform Matte Gunmetal finish covers the spoke faces, recessed center, outer rim and barrel. The protective matte clear coat helps maintain the low-reflection metallic appearance, while consistent surface preparation and coating application preserve the finish across the broad spokes and curved surfaces.

FAQs

1. Will These 21-Inch Forged Wheels Fit My Audi SQ5?

These wheels feature a 21×10 size, ET18 offset, 5×112 bolt pattern and 66.6 mm center bore. Fitment may vary depending on your SQ5's model year, brake configuration, suspension setup and tire dimensions. Please confirm your vehicle specifications before installation.

2. What Are the Weight and Load Rating of These Wheels?

Each wheel weighs 13.6 kg and carries a rated load capacity of 900 kg. The forged monoblock construction combines the center, five spokes and barrel in a continuous aluminum structure without separate bolted joints.

3. What Makes the Deep-Concave Five-Spoke Design Distinctive?

The wheel features five broad spokes extending from a recessed center toward the outer rim. Large openings between the spokes expose the brake area, while the concave profile adds depth to the otherwise clean and straightforward design.

4. What Type of Wheel Bolts Are Required?

The wheel uses a 15×32×R14 short ball-seat mounting specification. Compatible wheel bolts must match both the wheel's seat geometry and your vehicle's thread requirements. Check the mounting hardware and hub fit before installation.

5. How Should I Maintain the Matte Gunmetal Finish?

Use a mild, pH-neutral wheel cleaner and a soft microfiber cloth or brush. Rinse away brake dust and road contaminants regularly, and avoid abrasive compounds or gloss-enhancing polishes that may alter the matte surface.

6. How Long Does Production Take?

The production lead time for this forged monoblock wheel configuration is approximately 25 days after the design and specifications are confirmed. The schedule includes CNC machining, Matte Gunmetal finishing, dimensional inspection and dynamic balancing. Shipping time varies by destination.
