Overnight engine change for Reynolds Camaro

Team 18 has completed a precautionary overnight engine change on the David Reynolds car ahead of Saturday's action at the Penrite Oil Sandown 500.

Reynolds was third in Practice 1, before co-driver Warren Luff was 23rd in Practice 2.

The #20 TRADIE Beer Chevrolet was 17th in Practice 3, which was topped by fellow Camaro driver Jack Le Brocq.

Teams then completed rides after Practice 3, before the local squad went to work changing the engine on the TRADIE car.

A Team 18 spokesperson told Supercars.com the change was as a precaution, with the team identifying a loss of power down Sandown's long straights.

“Friday at Sandown went okay. Car pace is okay, just that the last last run in practice wasn't the best, probably made too good of a race car possibly and not the best quali car," Reynolds said.

"I’ve got some ideas in my head why that is, but I need to talk to Krusty [Richard Hollway, engineer] about it. But, all in all, good day. Luffy was on the pace, got some laps on good tyres. We’ve got a lot of data to pile through and come up with the best car for tomorrow.

“We rolled out fairly on the pace, I think track and tyre conditions probably helped us there, but, towards the end of the day, might have lost our way a little bit, but got some things to go through."

Friday was an otherwise smooth day for teams, with the Cameron Hill/Cameron Crick Matt Stone Racing entry sidelined for much of Practice 3 due to a suspected bent right-front shock absorber.

Rain is currently falling at Sandown Motor Raceway, setting the scene for a dramatic qualifying day ahead of Sunday's 500km feature race.

Supercars will return to the track on Saturday morning for Practice 4 at 9:55am, followed by Practice 5 at 12:05pm.

Drivers will tackle Boost Mobile Qualifying at 2:15pm, which will set the running order for the Top Ten Shootout at 5:25pm.
