Due to the rebranding of the MAXOne M1S Purple tire used in the Open Shifter and Open Shifter Masters classes, we had to modify the regulation accordingly. The new name for these tires is VEGA VAS Yellow. The tires, front and rear, have the same compound, structure and manufacture process as the previous MAXOne M1S Purple tire. Only the name and logo changed. See the bulletin and the updated 2019 Series Regulation below of on the REGULATION page.
