R72 JB/FC
The new five-spoke wheel combines futuristic design with technical sophistication. Its integrated aerodynamic ring, featuring distinctive grooved structures, is seamlessly embedded into the wheel and dynamically intersected by the spokes – a striking statement of form and function.
Thanks to its aerodynamic design, air turbulence is reduced and drag minimized, which can help improve driving stability. With its high load capacity, the wheel is ideal not only for sports cars but also for SUVs.

Diamond Cut
To produce mirror finishes and two-tone wheels, we use a diamond cut process.
Here the aluminum wheels are pre-painted and the surface is then turned using a diamond cutting tool. By removing a small amount of paint and aluminum, a shiny metallic, finely-honed surface is revealed. Diamond cut is performed especially on the wheel flange or on the spokes. This is how two-tone wheels are made – a real eye-catcher!
Undercut
Material that is not essential for wheel stability can go – thereby saving weight.
This principle of removing material behind the spokes that is not relevant to strength goes by the name of undercut for wheel manufacturing at the RONAL GROUP. Undercuts are produced either by machining or flowforming and can reduce wheel weight by between 600 g and 1.4 kg depending on dimension and design.
