Adopting the industry’s first hybrid machining, we have converted the popular 5-hole model 57 ANA to 6 holes for 4 WD. The design changed from 2 ? 5 design to 2 ? 6 design according to 6 hole formation. We follow the elements such as hybrid machining and optimize the balance for 4WD for each part such as the width of the spoke and the depth depth while following it. Furthermore, this 57 ANA-X sticks to the basic function, and by extending the rim by spinning, it adopts the RCF construction method which realizes a lighter and stronger rim by making detailed structure dense.
