74.1 mm center bore: if your vehicle's hub is smaller, a centering ring fills the gap and ensures the wheel is centered. Rings are supplied according to the vehicle details you provide.
TÜV approval: this model is certified by the German organization, the most demanding standard on the European market. The report lists the covered vehicles and, where applicable, the fitting conditions. Ask us for the report corresponding to your vehicle if needed.

Wheel machined to order

Specify your vehicle when ordering

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.

This process allows Concaver to offer deeply concave designs in large diameters at an accessible price.

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.
