About The VFF-103 Wheel: The curviest of the pack features a five split spoke design with rounded edges throughout. Its curved Y-spokes and rounded concavity allows for one of our deepest concave designs. What is Vorsteiner Flow Forged? The Vorsteiner Flow Forged Wheel technology produces wheels that are lighter in weight compared to a conventional cast construction, yet substantially stronger. The majority of surplus weight can be shaved by the use of less but stronger aluminum. In addition, we meticulously reduce the weight of the wheel utilizing back-pad pocketing as well as front and rear spoke pocketing. The Vorsteiner V-FF wheel fitments include a wide range of cars and wheel styles.
