74.1 mm center bore: if your vehicle's hub is smaller, a centering ring fills the gap and ensures the wheel is properly centered. Rings are supplied based on the vehicle information you provide.

TÜV approval: this model is certified by the German organization, the most demanding reference in 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 machined in advance: its bolt pattern (5 holes, from 108 to 130 mm) and offset (ET 10 to 52) are machined to your specifications. Enter your vehicle's exact model in the form above — without this information, the wheel cannot be manufactured. Unsure? Contact us before ordering; we'll determine the correct specifications together.

Specific offset: the wheel is supplied in ET 10 by default. If you want another value within the range, enter 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 information 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 painting.

Shipping

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

Bolt pattern and offset machined to your specifications
Maximum permissible load: 800 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 conventional cast wheel and a fully forged wheel — significantly stiffer and lighter than the former, without reaching the cost of the latter.

This process enables Concaver to offer deeply concave designs in large diameters at an affordable price.

Why Concaver

Machined to your specifications

Bolt pattern and offset made to measure: 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 the machining process.

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.
