CVR1 20×10.5" — Gloss Black Double
The Concaver CVR1
Five slender twin spokes and a pronounced concavity: the CVR1 is Concaver's founding design, the one that established the brand in the segment of supercar-inspired concave wheels.
Technical specifications
Wheel machined to order
This Concaver is not machined in advance: its bolt pattern (5 holes, from 108 to 130 mm) and its offset (ET 15 to 64) are made 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 15 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 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 20×10.5" wheel (sold individually)
- Hardware suited to your vehicle — included
- Centering rings suited to 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 permissible load: 980 kg per wheel
Construction: hybrid forged
Concaver uses Flow Forming, also known as flow forging: the wheel is stretched while hot as it rotates, densifying the material around the tire bead seat. The result lies between a traditional cast wheel and a fully forged wheel — considerably 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.
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 specify your vehicle when ordering.
