"It’s the first time on this tyre, but you never really feel those things too much unless you are changing tyre-to-tyre on the same day. We just rolled out, got the grip and just drove; everyone just adapted very quickly.
"We’ve tried different things today and always learning. For me, it’s the first time here in this car, so we’ll take something out of today and see what we produce tomorrow."
Davison was less than a tenth down on his teammate in Practice 2, with the two-time Bathurst winner making a marked improvement on his morning pace.
The 19-time race winner tested the compound late last year, and was pleased with the changes made throughout the day.
