The imortant bit (for me) is:
WHAT SUB-EVENTS WILL BE CONDUCTED?
There are 11 events over two-days. Four Motorkhanas (on the National circuit, two in front of the NASCAR garages, and one on the Thunderdome pit lane), a drag race, a sprint on the Thunderdome Legends course, an average speed run on the Thunderdome, three go-to-whoas (anti-clockwise on the National Circuit) and a one-lap dash around the Grand Prix circuit (Combination of the National circuit and Thunderdome).
ARE ANY SUB-EVENTS HELD ON DIRT OR GRASS?
No. All sub-events are held on the race tracks, sealed pit lanes or sealed parking areas.
HOW MANY CARS WILL COMPETE?
Entry is capped at 125 cars. The field will be split into two groups to minimize waiting time.
WHAT IS THE TIMETABLE?
Cars will be scrutineered at Calder Park on Friday between 10.00am and 2.00pm. Competition starts at 9.00am on Saturday is expected to conclude around 5.30pm. A competitors' BBQ will be held following Saturday's activities. Sunday's competition commences at 10.00am and is expected to conclude around 3.00pm. Presentations will be made following Sunday's activities.
DO I NEED A CO-DRIVER (NAVIGATOR)
Rally Masters has no navigation events however a navigator/co-driver is compulsory on the Thunderdome Average Speed run and optional on all other events except drag racing, where no navigator/co-driver is permitted. In the optional events, it is purely up to the team to determine whether it is more advantageous to run with or without a navigator/co-driver.
DOES MY CO-DRIVER (NAGIVATOR) HAVE TO DRIVE?
No. The navigators/co-driver's primary role is to help the driver correctly negotiate the various courses and monitor distance versus time on the Average Speed Run.
