Ozz Negri topped the time charts in Friday’s opening practice for the Sahlen’s Six Hours of The Glen at Watkins Glen.
The Brazilian reeled off a best lap of 1:36.705 halfway through the 60-minute session in the No. 60 Michael Shank Racing Ligier JS P2 Honda he shares with Olivier Pla and John Pew.
Negri kept three Corvette DPs behind, led by the No. 10 Wayne Taylor Racing entry of Max Angelelli, who was 0.387 seconds off.
Times were considerably faster than last year on the newly repaved circuit, with Negri improving the time he coincidentally set himself in a dry Practice 2 by 1.661 seconds.
Dane Cameron ended the session in third with the No. 31 Action Express Corvette DP (+0.576s), in front of the sister No. 5 car (+0.790s) and the No. 2 Tequila Patron ESM Ligier Honda (+1.119s) completing the top-five.
Colin Brown dominated proceedings in Prototype Challenge, mixing it up with the Prototypes by posting the 7th quickest time overall with the No. 54 CORE autosport Oreca FLM09 (+1.996s) and staying almost one second clear off Tom Kimber-Smithin in the No. 52 PR1/Mathiasen Motorsports car.
Dirk Werner led the way in GT Le Mans, reeling off a 1:43.574 in the No. 25 BMW Team RLL BMW M6 GTLM he shares with Bill Auberlen and features a stars-and-stripes livery this weekend.
Werner edged out the both Ford Chip Ganassi Racing Ford GTs, with just one thousandth of a second between himself and the No. 66 Le Mans class-winning chassis of Dirk Mueller.
GT Daytona saw the No. 6 Stevenson Motorsports Audi R8 LMS GT3 of Robin Liddell end up quickest, ahead of the No. 73 Park Place Motorsports Porsche 911 GT3 R of Joerg Bergmeister (+0.550s).
