Nick Percat has lamented a slow start to his Beaurepaires Tasmania SuperSprint weekend following a lowly run to 19th in Race 6 qualifying.
Percat fell victim to the all-new knockout qualifying ahead of the 44-lap Race 6, which will commence at 4:25pm AEST on Saturday.
The #8 R&J Batteries Commodore was forced to remain to the garage after the first five-minute session.
Percat was later seen remonstrating to his engineer Andrew Edwards after the session.
Speaking afterwards, Percat was at a loss to explain his lack of pace.

"I’m not sure what’s happening,” the four-time race winner said.
“Something’s going on because since Practice 2, every time I push the brake pedal, I put three wheels now to canvas.
"Which you have known me long enough, it’s pretty rare a lock-up like that happens.”
It was a morning of mixed results for Brad Jones Racing; Jack Smith impressed to score a career-best start of 10th, but was hit with a three-place grid penalty for impeding Jack Le Brocq.
Macauley Jones will start 17th, two places ahead of Percat, with Todd Hazelwood to line up on the back row.
Having compromised his tyre bank, Percat was unsure how his race would play out from a strategy standpoint.
“Big afternoon ahead,” he said.
“Not ideal but I’ve got to get the R&J Batteries car up the front again and figure out what’s going on.
“The issue is now that I have two flat-spotted tyres in my bank.
“The way the weekend works, we are limited on the number of tyres we’ve got.
“Our car is generally good on a longer run.”
Percat currently sits eighth in the standings following three top 10 finishes at Sandown last month.
Cars will hit the track for the 44-lap Race 6 at 4:25pm AEST.
The event will be broadcast live on Foxtel and will be streamed on Kayo with highlights on 7 and 7 Plus.
