The FK Ethos RT-57 is a split 5 spoke design that uses a unique reverse machining process called CNC (Computer Numerical Control) that creates highlights around each spoke of the wheel and also engraves the Falken logo. It utilizes side cavity casting to add depth and dimension to the split-spoke design from a side angle view and then CNC machined again from the side to highlight each cavity. If you want a wheel with the latest technology features and design, the RT-57 split-spoke wheel from FK Ethos is a wheel to consider.
