XIRON ProStock Series The XIRON League features annual sign-ups for Spark Racing Design’s most loyal viewers. The quickest sign-ups for Season 2 and beyond will enter the competition as AI racers, challenging for the XIRON Digital Cup. Those who are close but do not sign up fast enough to be entered into The XIRON League will be placed in the XIRON ProStock Series. Each year, the ProStock Series competitors will graduate to The XIRON League, as everyone else (including new viewers and previous XIRON League sign-ups) must sign-up to get back into the ProStock Series. This creates a cycle in which everyone has a chance to participate in XIRON SimRacing every now and then. QUESTIONS?
