Drive to your own level.
You have nothing to prove.
The Ferrari, Porsche and BMW drivers are likely wan...s anyway with all pose and little driving ability.
You have a great car, track tyres (slicks) could take several seconds off your lap time, if your going sideways your not going fast.
Learn the corners, brake points and be consistent.
Steer hard to get into the right place for corner entry and most of all maximise your corner exit speed.

I would love to have a go myself, I am waiting to get back to Wakefield near Goulburn to get the feel of the car driven hard.
