“Further Hi-Tec Oils APC Enduro Championship regulation freedoms have been designed to cater to competitors and teams headlined by a return to endurance racing,” a category statement read.
“These also include freedoms in re-fuelling systems such as a choice of dry breaks, fuel churns or rotary pumps, two tyre options (Hankook or Yokohama) and all-inclusive entry fees in a move to further smoothen the process.
