Christophe Bouchut and Dominik Farnbacher recorded the fastest laps in the respective Daytona Prototype and GT classes during Sunday's second day of Grand-Am testing at the 'Roar before the Rolex 24'.

The three-day session has 52 cars entered in preparation for the 47th running of the Rolex 24 at Daytona later this month, but Bouchut - driving for the new LevelFive Motorsports team - led the DP class with a lap of 1min 41.884secs in the #55 BMW Riley he will co-drive with Scott Tucker and Ed Zabinski. Farnbacher, meanwhile, lapped the #86 Farnbacher Loles Racing Porsche GT3 in 1min 51.424secs to join Bouchut in unofficially bettering the existing class lap records.

"Having a fast car actually has no affect on how you will do in the race," 1995 race winner Bouchut admitted, "When I won this race, I was 16th on the grid. But, especially for a new time coming to Daytona with a Daytona Prototype, it's a nice feeling [to be quickest]. We are not quite happy with our set-up right now, and we are working to be closer to [that] so, for sure, our time will be faster - and it would be nice to win the pole position."

Reigning IRL champion Scott Dixon led the second session with a lap of 1min 42.298secs in the #02 Chip Ganassi Lexus Riley, while Romain Dumas led the third and final session with a lap of 1min 42.154secs in the #7 Penske Racing Porsche Riley. In the GT class, David Haskell led the second session in the #70 Castrol Syntec Mazda RX-8, while Andy Lally was fastest in the final hour in the #67 TRG Porsche GT3.

Despite Bouchut's day two pace, Michael Valiante's lap of 1min 41.760secs - set in the #6 Michael Shank Racing Ford Riley on Saturday - remains the fastest lap completed during the opening two days of the test. SpeedSource Mazda's Sylvain Tremblay leads the GT class with a lap of 1min 51.205secs, recorded during Saturday's opening session.

Rob Finlay had a scare late in the afternoon when he cut a tyre and spun the #2 Childress-Howard Motorsports Pontiac Riley, but he avoided hitting anything and escaped with only bodywork damage. Finlay will co-drive the #2 with three-time winner Andy Wallace, IndyCar Series regular Danica Patrick and NASCAR Sprint Cup Series driver Casey Mears in the season-opener later this month.
