CVR9 21×11" — Matte Black
The Concaver CVR9
The latest design in the range: slim spokes, a deep concave profile and a carefully finished edge. Designed for large diameters.
Technical specifications
Wheel machined to order
This Concaver is not pre-machined: its bolt pattern (5 bolt holes, from 108 to 130 mm) and offset (ET 11 to 55) are made to your specifications. Enter your exact vehicle model in the form above — without this information, the wheel cannot be manufactured. Not sure? Write to us before ordering; we'll determine the correct specifications together.
Specific offset: the wheel is supplied in ET 11 by default. If you want another value within the range, enter it in the form: machining to this specification costs €20 per wheel, added automatically to the cart.
You place your order
Choose the diameter, width and color, then enter your vehicle details and, if needed, the desired offset (+€20 per wheel).
We verify the specifications
We check the bolt pattern, offset and clearance on your vehicle before starting production.
The wheel is machined
Allow approximately one additional week for machining or a custom paint finish.
Shipping
Delivered with the hardware, centering rings and matching center cap.
What's included
- Concaver CVR9 21×11" wheel (sold individually)
- Hardware adapted to your vehicle — included
- Centering rings adapted to your vehicle — free with every order of 4 wheels
- Matching Concaver center cap — always included, regardless of quantity
- TÜV approval
- Bolt pattern and offset machined to your specifications
- Maximum permitted load: 900 kg per wheel
Construction: hybrid forged
Concaver uses Flow Forming, also known as flow forging: the wheel is stretched while hot as it rotates, which densifies the material around the tire bead seat. The result lies between a traditional cast wheel and a fully forged wheel — significantly stiffer and lighter than the former, without reaching the cost of the latter.
Why Concaver
Machined to your specifications
Custom bolt pattern and offset: the wheel adapts to your vehicle, not the other way around.
TÜV approved
The most demanding European certification, rare in this price segment.
Pre-purchase advice
Bolt pattern, offset, clearance, camber: we confirm the fitment with you before machining begins.
Fitting and hardware
Unlike most brands, the appropriate hardware is included with your Concaver wheels, along with the centering rings and center cap. Simply specify your vehicle when ordering.
