The first day of the Coates Hire Ipswich SuperSprint sees three practice sessions, with the first exclusively for additional drivers (usually enduro co-drivers).
With a range of drivers taking part - including some unconfirmed drivers, with Aaren Russell and Karl Reindler in LDM cars, and Macauley Jones in the third BJR Commodore - preparation for the PIRTEK Enduro Cup has well and truly started.
Two hour-long sessions follow, with the drivers tuning their V8 Supercars before Saturday's two qualifying sessions and races. The V8 Supercars Dunlop Series, Touring Car Masters and Formula 4 will also run as part of the event.
