CVR9 21×11.5" — Titanium
The Concaver CVR9
The latest design in the range: slim spokes, a deep concave profile and a carefully finished lip. Designed for large dimensions.
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 machined to your specifications. Enter your exact vehicle model in the form above — without this information, the wheel cannot be manufactured. Unsure? Contact us before ordering; we will 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, 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 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 custom paint.
Shipping
Delivered with hardware, centering rings and the matching center cap.
What's included
- Concaver CVR9 21×11.5" wheel (sold individually)
- Hardware suitable for your vehicle — included
- Centering rings suitable for 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 forming: the wheel is stretched while hot as it rotates, densifying 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 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.
Installation 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.
