Sandown winners Garth Tander and Warren Luff have fired a warning shot at lapped drivers ahead of next month’s Supercheap Auto Bathurst 1000.

After taking a hard earned victory, the duo did not hold back when asked of their view on the behaviour of the slower runners during the Pirtek Enduro Cup opener.

Tander took particular umbrage to drivers reacting slowly to blue flags, which are delivered under instruction from race control in the Supercars category.

While Sandown features ample room for overtaking, the 39-year-old fears the issue could be even worse at Bathurst.

“There were some very average performances by some of the lapped cars,” he said of Sunday’s race.

“I would have sent a lapped car off but I didn’t want to create a Safety Car.

“It was just ridiculous. Hopefully we can tune that up in the future.

“If you get stuck behind them across the top of the mountain and they’re wobbling around it can cost you a second.”

Co-driver Warren Luff echoed Tander’s thoughts, but said that the teams should play a greater role in warning their drivers that they are about to be lapped.

“All the teams have got the telemetry, they can see where you are on track,” said Luff.

“Yes, it’s the job of the officials to have the blue flags out, but it’s up to the teams as well.

“They know here their cars are on track, they know where they are in lap position, and when you’re about to go a lap down, or when you’re two or three laps down, get the hell out of the way.

“There was some pretty average driving out there. Thankfully it didn’t play a part in the final result, but some people, and some teams, need to do a better job of what they’re doing in the pits.”
