The brand new Corvette Daytona Prototype continued to lead the way around Daytona International Speedway claiming the top four positions in the final practice before qualifying for the 50th edition of the Rolex 24 at Daytona.

After Max Angelelli led the opening session for Suntrust Racing it was Alex Gurney who put the red no.99 Gainsco backed Bob Stallings entry top of the second session ahead of the Spirit of Daytona entry.

The Suntrust entry was third ahead of the no.9 Action Express Racing car.

Action Express – overall winners in 2010 – are the only squad to have two of the new Corvette in the race and while one challenged the leader the other ended the session early after an engine fire brought Darren Law's no.5 car to a halt at the end of the session.

Law was subsequently cleared to continue, though the car is unlikely to reappear for qualifying. The no.01 Chip Ganassi Racing car also suffered a – less dramatic – engine failure and is also likely to miss qualifying.

The only car that failed to make a lap in the opening session – the no.8 Starworks Motorsport Riley of Ryan Dalziel, Lucas Luhr, Allan McNish, Alex Popow and Enzo Potolicchio – was seventh fastest, sixth tenths off the top time of the session.

Andy Lally turned the fastest GT lap of the session for Magnus Racing. Bill Auberlen was – again – second fastest with Robin Liddell third in Stevenson Motorsports' no.57 Chevrolet Camaro. The top 14 GT entries – including five different brands were covered by less than a second.
