Max Angelelli and Martin Ragginger led their respective classes as testing for the 48th Rolex 24 wrapped up at at Daytona International Speedway on Sunday.

Angelelli ran a lap of 1min 40.888secs in the #10 SunTrust Ford Dallara to lead the Daytona Prototype class, while Ragginger was fastest in GT with a lap of 1min 49.627secs in the #23 Alex Job Racing Porsche GT3.

Following two days of unseasonably cold temperatures - with Saturday morning's session scrubbed due to sleet and icy conditions - Sunday practice was run under sunny skies with temperatures in the mid 40s Fahrenheit. The Rolex Series sessions ran incident-free, with the only stoppages for minor spins, debris and a blown engine.

Angelelli also won bragging rights as favourite to claim the Rolex 24 pole - with qualifying set for Thursday 28 January - by turning a lap of 1min 40.466secs in Friday practice. Quickest overall in GT was Leh Keen, who ran 1min 49.214secs in the #41 Dempsey Racing/Team Seattle Mazda RX-8 during Saturday night practice.

Angelelli, however, insisted that winning the pole was not a priority for the SunTrust Racing team, which won the 2005 race with Wayne Taylor and Emmanuel Collard partnering the Italian. Co-driving with Angelelli this year will be Wayne and Ricky Taylor and Pedro Lamy.

"I want to win the race - we want to win the race," Angelelli said, "That's the only thing that counts. We were very happy with this test. We were very happy with the car. Everything was perfect."

Michael Valiante was second fastest on Sunday, with a lap of 1min 41.182secs in the #6 Michael Shank Racing Ford Riley shared by AJ Allmendinger, Brian Frisselle and Mark Patterson. Alex Gurney led Sunday afternoon's session with a lap of 1min 41.319secs in the #99 GAINSCO Chevrolet Riley that he will share in the Rolex 24 with Jon Fogarty, Jimmy Vasser and four-time NASCAR Sprint Cup Series champion Jimmie Johnson.

Second in the combined test, however, was Scott Dixon in Chip Ganassi Racing with Felix Sabates' #02 Target/TELMEX BMW Riley, followed by Valiante, Scott Pruett in Chip Ganassi Racing with Felix Sabates' #01 TELMEX/Target BMW Riley and Christophe Bouchut in the #55 Level 5 Motorsports/Supercar Life Racing BMW Riley.

Angelelli and Pat Long led their respective classes on the opening day of the Roar Before The 24, a three-day session staged to open the 2010 Grand-Am Rolex Sports Car Series presented by Crown Royal Cask No. 16 schedule.

Angelelli led the Daytona Prototypes with a lap of 1min 40.466secs, set late in the morning session, while his three team-mates all took turns at the top of the afternoon session, which was run in drizzly conditions that resulted in slower times.

"I am very happy with today," Angelelli said, "All the drivers were very good, we are very happy with the car, and it is driving really well. At the moment, we are just running laps. We are all right there. We are looking forward to the race. I feel all we need right now is to wash it and we can go racing."

Gurney was fastest in the afternoon session with a lap of 1min 41.761secs, but maintained that he was not chasing ultimate pace.

"We had a different programme today, getting a bunch of things done for the Rolex 24," the American said, "We ran our race engine, we bedded in a bunch of brakes. The car has a good balance. We ran a lot of laps under damp conditions, and it felt nice. We have no idea of how we are, speed-wise, but so far it looks okay."

Spencer Pumpelly led Sunday afternoon GT practice with a lap of 1min 49.700secs in the #71 TRG Porsche GT3 co-driven by Tim George Jr and Bobby Labonte.

"We've been making the car better in every session, and making it more drivable to make it consistent through a run," Pumpelly said, "Getting to run with Tim George Jr and Bobby Labonte - along with Porsche factory drivers Romain Dumas and Timo Bernhard - in the Rolex 24 is a dream come true. I can't wait."

Keen, Ragginger and Pumpelly were trailed in GT by Jorg Bergmeister in the #67 TRG/Flying Lizard Motorsport Porsche GT3 and Sylvain Tremblay in SpeedSource's #70 Castrol Syntec Mazda RX-8.

However, the GT class turned in its fastest speeds in the afternoon, as Long closed out the day with a lap of 1min 49.961secs in the #67 TRG/Flying Lizard Motorsports Porsche GT3 co-driven by Bergmeister, Seth Neiman and Johannes van Overbeek.

Ragginger was second among the two GT practices with an afternoon lap of 1min 40.216secs, followed by Andy Lally in the #66 TRG Porsche at 1min 50.276secs and Pumpelly's 1min 50.636secs effort.

Pacing the GT class Friday morning was Tremblay, followed by team-mate Anthony Lazzaro in the #69 SpeedSource FXDD Mazda RX-8.

"Today was the first time our #70 car ever turned a wheel, and the #69 is also brand new, so today was a testament to the hard work done by all of the guys at SpeedSource and the support of Mazdaspeed and Castrol," the 2008 Rolex 24 GT winner commented, "To unload brand new and to be 1-2 in the opening session, and have our partner Dempsey Racing also fast, demonstrates the effort we've made to win this race - again."

The co-owner of the two-car Dempsey Racing programme was happy overall.

"We had a good weekend, and we learned a lot," said Patrick Dempsey, "We have a few things we still have to take care of, but we will be back strong. This is the first time we've been together as a two-car team, and our chemistry is working real good. We're having a great time."
