The Sprint Series
Classes: GT, GTA, GTS, TC, TCA, TCR
Sprint: maximum race time of 50 minutes, with no required pit stops and distance travel/number of laps changes with each new track and track conditions.
-TC, TCA, TCR races are 40 minutes long with laps and distances also changing between each track.
SprintX: races are 60 minutes, with one required pit stop, at least 25 minutes into the races, with the pit window opening. Pit stop must meet a minimum entry to exit time requirement.
GTS/GT4: Smaller-power model sports cars with a lower permissible prep level. SRO GT4 cars–RWD, FWD and AWD–are permitted as are turbocharged and normally-aspirated vehicles.
Power range is 300-400 whp. Each GT4 car is homologated through the SRO, while also meeting each classes safety requirement. The SRO sets restrictions per make and model such as: the standard manufacture inputs, ride height, restrictor, tire size, and weight.
Adjustments of Performance (BOP): The Pirelli World Challenge reserves the right to make adjusts towards the SRO’s restrictions of the vehicles, insuring a fair and even performance between the manufactures.
