“I'm really happy about the car, about the track, everything is new for me,” said Premat.
“The car is running quite good. We need to adjust a few things in the rear because the traction is really bad, but we didn't put fresh tyres on, so I think the lap time that I did was really good.
“We are looking forward definitely. I think it will be really hard this afternoon for the qualifying compared to the others because they know quite well the track, but it's fine.
“I'm really happy right now, I didn't crash the car, didn't put it in the walll, so right now it's fine.”
“I love street circuits and Adelaide is fantastic,” said Premat.
“The first corner is quite good, it's very fast going through the kerbs, and then after that in 4, 5, 6, it's very tricky. It's second gear and you really need to avoid snap oversteer otherwise you will go in the wall.
“After that, Turn 8 is pretty rough, but it's nice, I really love it.”
The full V8 Supercars Championship field will hit the track for Practice 3 at 1210 local time.
