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 according to the vehicle 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 machined in advance: its bolt pattern (5-lug, from 108 to 130 mm) and its offset (ET 10 to 52) are machined to your specifications. Enter the exact model of your vehicle 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, 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 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 extra week for machining or custom paint.

Shipping

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

What's included

Concaver CVR8 21×9" 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: 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, increasing material density around the tire bead seat. The result falls between a classic cast wheel and a fully forged wheel — significantly stiffer and lighter than the former, without 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

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.

Advice before purchase

Bolt pattern, offset, clearance, camber: we confirm 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.
