How many laps are you doing? I have done a drive day in Perth (barbagallo) So a bit different to Eastern creek. We bought my dad a 5 lap drive for his birthday and me my brother, cousin and her husband and uncle also did the 5 laps at the same time.
My experience was it wasn't a life changing moment lol, I had done a couple track days on my motorbike on the same track so i knew the track and was use to riding my own line, braking and accelerating when i wanted with no one really telling you what to do. In the V8 you have someone next to you giving you some guidance, they set cones and markers on the track showing you where to drive on the track and when to brake and accelerate.
Cause there was 6 of us we all bought the optional USB recording so we could compare times and top speeds ect, my cousins USB didnt work when she got home so basically wasted $50, Video quality on the USB was like 144p quality so not great but shows you lap times and your speed as you go around the track.
Cause we were trying to be competitive you only get 3 laps to get your best times (1 lap if you do the 3 lap drive) because your first and last laps include leaving and returning to the pits.
On our track we only really used 3rd and 4th gear and the quickest i got on the long bask straight was close to 200kph so you do get to go quickish lol felt slow to me as my bike was topping out 5th gear well over 200ks on the same back straight. If you haven't driven a v8 commodore before the car will probably feel quick to you but to me they didnt seem that quick. My vy ss was dynoed at 370rwhp the v8 super cars were advertised as 470hp im guessing at the motor not the wheels. The v8 supercar obviously has slick tyres, race suspension and stripped out interior, rollcage ect. Just a modified commodore or falcon really.
It was a good day but depending on your experience will determine what you think of it. For me was a little underwhelming since i have been on the track with a bike and drive a v8 everyday lol
