You should be three parts…
3 part wheels offer many advantages in comparison with conventional onepart wheels:
The rotationally symmetric production of a three-part rim causes a consistent distribution of material. So no imbalance emerges which in turn causes a better concentricity of the wheel that has positive effects especially in high speed and is much better than with onepart wheels.
The high material compression of the special Schmidt manufacturing process makes it possible to create extremely thin wall thicknesses. This leads to a radical weight reduction.
Last but not least threepart wheels offer more diverse assembling possibilities. You can adapt the wheel optimally to your car, width and offset are variable. Beyond 3part wheels have a better reparability and a deeper bed than onepart alloy wheels.
