The Concaver CVR1

Five slim twin spokes and a pronounced concavity: the CVR1 is Concaver's signature design, the model that established the brand in the supercar-inspired concave wheel segment.

67.1 mm center bore: if your vehicle's hub is smaller, a centering ring fills the gap and ensures the wheel is centered. They are supplied according to the vehicle details you provide.
TÜV approval: this model is certified by the German organization, the most demanding reference on the European market. The report lists the covered vehicles and, where applicable, the mounting 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-lug, from 108 to 130 mm) and its offset (ET 20 to 64) are machined to your specifications. Enter the exact model of your vehicle 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 appropriate hardware, centering rings and center cap.

What's included

  • Concaver CVR1 23×10" 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
  • Bolt pattern and offset machined to your specifications
  • Maximum permitted 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 along 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 affordable price.

Why Concaver

Machined to your specifications

Bolt pattern and offset are custom-machined: 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 fitment with you before machining begins.

Mounting 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.
