Vossen Forged Series 21 S21-01 Monoblock Wheel
The pinnacle of Vossen Forged design, Series 21 features aggressive and unique designs where any concept can be realized for almost any vehicle, from exotic hypercars to off-road trucks.
The Factory
- Vossen is one of the few companies worldwide that produces forged wheels entirely in-house. Located in Miami, Florida, Vossen’s state-of-the-art, TUV Verified facility is equipped with an extensive range of new machinery.
Manufacturing
- Vossen Forged wheels undergo a rigorous manufacturing process to meet the highest standards of design and quality.
Engineered Art
- Vossen bridges the gap between the precision of custom forged wheels and the affordability of cast wheels. The company offers custom CNC machining to fit nearly any bolt pattern, center bore, and offset with unmatched precision and efficiency.
Design
- Vossen ensures precise fitments by measuring over 100 data points on each vehicle. Each wheel is custom-made for specific vehicle makes and models.
Concave Profile Flexibility
- All Vossen Forged wheels are machined using Vossen’s proprietary forging design. This design allows for the creation of wheels with an efficient spoke profile, incorporating extra material on the face to support profiles ranging from flat to super deep concave. This innovative method enables the production of an 8.5” width wheel with maximum concavity equivalent to a 12.5” wheel.
Finishing
- Vossen’s in-house finishing facility uses advanced equipment to achieve the highest quality finishes. From ceramic polishing to powder coating, Vossen Forged wheels maintain industry-leading quality by meticulously overseeing every step of the process.
- Hand Prep: Step 1 – To achieve premium finishes, each wheel is hand-sanded and deburred after machining. Wheels receiving a brushed finish undergo an extensive hand-sanding process, taking up to five hours each, to ensure an even, brushed surface throughout.
- Brushing & Polishing: Step 2 – The most labor-intensive yet rewarding part of the finishing process is brushing and polishing. Offered as upgrade options in every Vossen Forged line, brushed wheels showcase the beauty of the forged aluminum grain, while full ceramic polishing creates a mirror-like finish. Combining brushing and polishing provides the best of both worlds.
- Pre-Treatment: Step 3 – After hand prep, all wheels undergo a seven-stage pre-treatment cleansing process to remove impurities before powder coating. This pretreatment ensures a stronger and more consistent finish once powder coated.
- Powder Coating: Step 4 – Vossen’s in-house powder coating facility, designed specifically for wheels, uses state-of-the-art components and the highest quality powders to produce a uniform finish that lasts.
- Final Visual Inspection: Step 5 – After powder coating, a final inspection is conducted to check the quality and consistency of the finish’s appearance, using a film thickness gauge to ensure uniformity. Once inspected, each wheel is cleaned and packaged for shipment to the customer.
- Solid Colors: Vossen Forged wheels are available in solid colors as a standard option, with shades and finishes including gloss, matte, satin, and textured options.
