Rob Huff was quickest of all in the second Macau Guia Race practice session, though the battle for track position and clean air was quickly becoming the story of the day.
As is so often the case at Macau, traffic is proving a difficult challenge to overcome for all of the drivers this weekend.
After placing third in the first practice period, the MG X-Power star fared the best in this regard during free practice two, managing to put together a lap time of 2 minutes 32.991 seconds.
It was the Teamwork Motorsport cars which were quickest out of the gates however, with Jason Zhang leading the way early on.
In a similar vein to the day’s prior track action though, practice soon came to a temporary halt due to an incident on track.
This time, the driver in strife was Ng Kin Veng who lost the rear end of his SLM Racing Team Audi through the high-speed first corner, and consequently slid off into the outside barriers.
With the right-hand side of his car significantly damaged, Ng had no choice but to pull over and wait for outside assistance.
Proceedings got back underway again after around fifteen minutes, and Huff was quick to get out of the pit-lane in order to secure a reasonable track position, allowing him the chance to overhaul Zhang at the top of the leaderboard.
In the end, practice one pace-setter Filipe de Souza would also improve to go up into second place, with Zhang demoted to third by the time the chequered flag was waved.
The two TCR China championship contenders were next up, with Ma Qing Hua in fourth, nearly 1.8 seconds faster than the traffic-stricken Rodolfo Ávila in fifth.
After a tricky opening session earlier on in the day, Lo Sze Ho improved up to sixth for Maximum Racing on this occasion in his older FK2 shape Honda Civic.
Three tenths of a second further back, Sunny Wong was the last of the Shell Teamwork Motorsport cars, and the last of the drivers to break the 2 minutes 40 seconds barrier.
Andy Yan was next up in eighth position for MG, while the two Honda FK7s of James Tang and Eurico de Jesus rounded out the top ten.
Qualifying is next up, and is set to get underway on Saturday at 09:45 CST (01:45 GMT).
