In tricky conditions more reminiscent of Mardenborough’s homeland Wales than Thailand, Mardenbourgh was always near the top of the time sheets.
Eventually losing out on pole by five hundredths of a second to Lexus driver Ryo Hirakawa, Mardenbourgh had to be content with two fastest sector times.
In recent weeks Mardenborough has made significant progress in his Super Formula rookie season and he goes into tomorrows Super GT race on a high feeling that progress is rapid.
“I am in my rookie seasons in both Super GT and Super Formula. After the summer break I am feeling stronger and the lap times reflect that,” he said.
“Now I need to string my speed together over a weekend to capitalise. Thailand looks like it could be the turning point in terms of results.”
The Welshmen will team up with regular teammate Hiro Yasuda tomorrow.
Mardenborough finished second in the GT300 class here in Thailand 12 months ago.
The race can be watched at live.NISMO.tv at 9:00am (UK), 10:00am (Europe), 5:00pm (Japan) and 3:00pm local time in Thailand.
