Xcel Motorsport's Patrick Heuzenroeder set the pace in the first Free Practice session for the GB3 Championship at Autodromo Nazionale Monza on Friday morning.
The Australian registered a best time of 1m43.583s, just 0.010s away from yesterday's testing pace, with his session topping time coming with around seven minutes remaining in the 45-minute practice.
Heuzenroeder was just over a tenth of a second quicker than yesterday's pace-setter Alex Ninovic, while Xcel's Kabir Anurag continues to run at the sharp end, and was third fastest this morning, replicating his performance from Thursday.
JHR's Noah Lisle was fourth quickest and only 0.030s away from the Singaporean, while Hillspeed newcomers Maxim Rehm and Newman Chi were an impressive fifth and sixth quickest, and split by 0.020s.
Argenti with Prema's Reza Seewooruthun was next up in seventh, half a tenth further back with the second Xcel car of Jack Sherwood eighth.
Lucas Fluxa ensured all three Hillspeed cars were inside the top-10, which was completed by Hitech's Deagen Fairclough.
The second and final Free Practice session at Monza is due to commence at 13.30 local time (12.30 UK).
