CVR1 20×10" — Glossy Double Black
The Concaver CVR1
Five slim twin spokes and a pronounced concave profile: the CVR1 is Concaver's signature design, the style that established the brand in the supercar-inspired concave wheel segment.
Technical specifications
Machined to order
This Concaver is not machined in advance: its bolt pattern (5 bolt holes, from 108 to 130 mm) and offset (ET 20 to 48) are machined to your specifications. Enter your vehicle's exact model in the form above — without this information, the wheel cannot be manufactured. Not sure? Contact us before ordering; we'll determine the correct specifications together.
Specific offset: the wheel is supplied in ET 20 by default. If you want another value within the range, indicate it in the form: machining to this specification costs €20 per wheel, automatically added 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 matching center cap.
What's included
- Concaver CVR1 20×10" wheel (sold individually)
- Hardware adapted to your vehicle — included
- Centering rings adapted to your vehicle — free with any order of 4 wheels
- Matching Concaver center cap — always included, regardless of quantity
- TÜV approval
- Machining of the bolt pattern and offset to your specifications
- Maximum permissible load: 760 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 sits between a conventional cast wheel and a fully forged wheel — significantly stiffer and lighter than the former, without the cost of the latter.
Why Concaver
Machined to your specifications
Bolt pattern and offset made to measure: the wheel adapts to your vehicle, not the other way around.
TÜV approved
The most demanding European certification, rare in this price segment.
Advice before purchase
Bolt pattern, offset, clearance, camber: we confirm the fitment with you before starting machining.
Fitting and hardware
Unlike most brands, the appropriate hardware is included with your Concaver wheels, along with the centering rings and center cap. Simply provide your vehicle details when ordering.
