CVR5 21×11.5" — Carbon Graphite
The Concaver CVR5
Slim split spokes and a flush rim, inspired by Italian supercar wheels. A design that visually lengthens the vehicle.
Technical specifications
Wheel machined to order
This Concaver is not pre-machined: its bolt pattern (5 holes, from 108 to 130 mm) and offset (ET 17 to 59) 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 17 by default. If you want another value within the range, indicate 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 confirm 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 custom paint.
Shipping
Delivery includes the hardware, centering rings, and compatible center cap.
What's included
- Concaver CVR5 21×11.5" wheel (sold individually)
- Hardware compatible with your vehicle — included
- Centering rings compatible with your vehicle — free with any 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: 980 kg per wheel
Construction: hybrid forged
Concaver uses Flow Forming, also known as flow forming: the wheel is stretched while hot as it rotates, which densifies the material around the tire bead seat. The result falls 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
Bolt pattern and offset made to order: 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 compatible hardware is included with your Concaver wheels, along with the centering rings and center cap. Simply specify your vehicle when ordering.
