Wheel machined to order

Specify your vehicle when ordering

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. Not sure? Contact 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, 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

Delivered with the appropriate hardware, centering rings and center cap.

What's included

  • Concaver CVR6 21×11.5" wheel (sold individually)
  • Hardware suitable for your vehicle — included
  • Centering rings suitable for 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 load rating: 920 kg per wheel

Construction: hybrid forged

Concaver uses Flow Forming, also known as rotary forging: the wheel is stretched while hot as it rotates, which densifies the material in the tire bead area. The result falls between a conventional 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.
