Ozz Negri kept the Ligier JS P2 chassis atop the timesheets for the third straight practice session ahead of Saturday’s 63rd Mobil 1 Twelve Hours of Sebring.
Negri posted a best lap of 1:52.096 in the No. 60 Michael Shank Racing Ligier JS P2 Honda.
The No. 57 Krohn Racing Ligier JS P2 Judd and No. 5 Action Express Racing Corvette DP were second and third, respectively.
Combined, in all four pre-qualifying practice sessions, these three cars have swept the top three, although each has led a session at least once.
The No. 1 Tequila Patron ESM HPD ARX-03b had its best session of the week, with Ryan Dalziel clocking in fourth overall at 1:52.899. Dane Cameron completed the top five in the No. 31 Action Express Racing Corvette DP.
Other class leaders in the final pre-qualifying practice included Martin Plowman (No. 16 BAR1 Motorsports Oreca FLM09) in Prototype Challenge, Patrick Pilet (No. 911 Porsche North America Porsche 911 RSR) in GT Le Mans and Spencer Pumpelly (No. 73 Park Place Motorsports Porsche 911 GT America) in GT Daytona.
Plowman got out in the repaired, single BAR1 entry, which had an accident during Thursday night practice with co-driver Tomy Drissi behind the wheel.
A scant 0.372 of a second covered first through eighth in GTLM, while GTD saw the top seven covered by 0.998 of a second. Dirk Werner saw his lap time beat first by Kaffer, then by Pilet to end the session.
There were no red flags in the session, and only the No. 81 GB Autosport Porsche 911 GT America did not go out.
Qualifying is the TUDOR Championship’s next on-track session at Sebring, and begins at 4:20 p.m. ET and local time.
