Running an additional driver, however, directly eats into the practice time for the primary pilot to set-up the car for the weekend's racing.
Although the extra sessions will take place at the event's leading up to the Pirtek Enduro Cup, V8 Supercars competition director Damien White stresses that any non-primary driver will be eligible.
“It's listed as an additional driver session as it's not specifically for a teams' nominated Enduro Cup co-drivers,” he said.
“Teams can certainly use it for them, however the option is there if a team wants to nominate someone out of the V8 Supercars Dunlop Series for example.”
