Flow Forming Manufacturing for Improved Performance

This method produces a wheel that is lighter and stronger than a conventional cast wheel, which improves the car's responsiveness, handling, and ride comfort.

Specifically, the rim flange is heated and then drawn by rollers after casting. The metal becomes denser, allowing material to be removed while maintaining the same strength: the weight reduction amounts to up to 30% compared to a cast aluminum model.

Certifications and Compliance

These rims are certified JWL and VIA, which ensure the rim's structural strength in accordance with Japanese standards. 9 of the 20 available sizes also come with a TÜV report : The corresponding certificate can be downloaded from the “Certification by Size” table above. Other sizes are covered solely by JWL/VIA certifications.

Installation: What to Expect

The order is delivered complete : 4 centering rings (73.1 → 64.1 mm) and mounting nuts are included. Allow 30 to 45 minutes for all four wheels using a jack and a torque wrench. Follow the torque specifications listed in your vehicle’s manual and retighten the fasteners after driving the first few kilometers.

Tire installation should be performed by a properly equipped shop, with a balance check after installation.

Shipping and Packaging

Each wheel rim is individually packaged, protected on both sides, and fully wrapped in plastic. This product is shipped separately from the rest of your order.
