Bryce Fullwood set the pace in Friday practice for the penultimate round of the 2019 Dunlop Super2 Series, notching a new practice lap record at the Penrite Oil Sandown 500.
The MW Motorsport driver turned a 1:08.2230s after the chequered flag had flown in the second of two 40-minute practice sessions.
Fullwood's best proved to be 0.3590 seconds quicker than the previous practice lap record, set by Garry Jacobson in 2018, aboard a MWM Nissan Altima.
The series leader finished opening practice fourth and went on to take top spot on combined times, 0.2159 seconds clear of Image Racing's Jordan Boys, who enjoyed a stellar day.
Across both practice sessions, Fullwood was late to join the party and had been at the foot of the order for some time before launching up the timesheets.
Boys (pictured below) was quickest in the opening session with a 1:09.0728s, which would've only put him 10th best for the day if he wasn't able to improve in the second session.
The 21-year-old is yet to start a race from inside the top 10 this season but appears well placed to change that this weekend.
In another MWM Nissan Altima, Zane Goddard was third on combined times, ahead of Triple Eight's Kurt Kostecki and Garry Rogers Motorsport's Dylan O'Keeffe.
Tickford Racing's Thomas Randle ended his day sixth overall, having finished the morning session as the runner-up driver.
Brenton Grove was third quickest in the morning for Triple Eight and ultimately finished the day seventh overall, ahead of Eggleston Motorsport's Will Brown.
The Eggleston trio of Brown, Jack Perkins and Justin Ruggier looked to have a rough day of practice, with Perkins and Ruggier the slowest two cars in 14th and 15th respectively on combined times.
Image Racing's Adam Marjoram finished ninth, ahead of Jack Smith who caused two red flag stoppages in the opening session and one in the second leg.
Smith beached his SCT Logistics Holden twice at Turn 1 in the morning and again at Turn 9 in the afternoon, which has proved to be a difficult section for many drivers.
Tyler Everingham was 11th, from Matthew Chahda and Ash Walsh, followed by the Eggleston pair of Perkins and Ruggier.
The on-track action resumes tomorrow with ARMOR ALL Qualifying for Race 1 at 11:55am local time, followed by the race Saturday afternoon.
