Brix and Borcheller completed the top five in the #77 Doran, taking the championship lead in the process after Oswaldo Negri and Mark Patterson, who came into the race as the leading series regulars, could only finish 19th in a car loaned from rival outfit Tuttle Team SAMAX. Fifth was a career-best result for Brix, and was Borcheller's best run since he finished fourth in the September, 2005 event at Watkins Glen International.
Similar to the dominating performance by Pruett and Diaz in the Daytona Prototype category, the GT pole sitting car also went on to claim the class win in the 100-lap race, as Kelly Collins and Paul Edwards returned Kevin Buckler's #64 TRG Pontiac GTO.R to victory lane, repeating that particular car's Mexican victory last November.
Collins started the machine on the GT pole, and kept the car near the front of the class pack throughout his stint. Despite losing several positions at the start of the race, Collins rebounded and benefited from the lap 46 caution period to turn in a quick pit stop that propelled his teammate Edwards back to the front of the class for good.
“We played the strategy great today,” said Collins. “The guys in the pits kept us out during the yellow until we got the 'wave by' which was lucky for us as I really thought we only had a second or third place car today. There was a lot of craziness in traffic and the track got really greasy early on, but it is nice to get my first in the Pontiac with TRG and iRise.”
When the caution flag came out, the #64 machine was between the pace car and the overall race leader. By rule, each car between the pace car and the lead car is given a “wave by,” in which cars positioned ahead of the race leader are allowed the pass the pace car and join the tail end of the field. As a result, the #64 Pontiac put a lap on its competitors, one it would give back during a later caution flag.
Collins handed the car over to Edwards during the caution, and Edwards, who shared last year's Mexico City win with Jan Magnussen, stayed in front for the remainder of the race, winning by a 12.564-second margin over the #80 Shoes for Crews Porsche GT3.
“I got the car in the lead and was able to run good laps and bring it home,” said Edwards. “The car was falling off a little, as we were struggling to keep pace during the race. The strategy gave us track position and we were able to win.”
The #80 Synergy Racing machine, co-driven by Leh Keen and David Murry, started fourth on the class grid, and was the only GT machine to finish on the same lap as the #64 car. The runner-up result erases a disappointing 22nd-place class finish in the Rolex 24 At Daytona, and puts the duo in good shape in the GT championship standings heading into round three at Homestead-Miami Speedway.
Finishing third was the #65 TRG/F1 Air Pontiac GTO.R, which was qualified fifth by Marc Bunting and finished by Andy Lally. In La Gran Final de la Serie Rolex Sports Car, the 2005 season finale at the Mexico City circuit, Murry passed Lally on the final lap to clinch the GT championship for then-teammate Craig Stanton, by a one-point margin over the #65 car teammates. However, this year's third-place run puts Bunting and Lally atop the 2006 GT driver standings, holding a nine-point advantage over Collins, Edwards, Robin Liddell, Wolf Henzler and Spencer Pumpelly.
Liddell and Henzler, sharing the #72 Tafel Racing Porsche GT3 finished fourth. Liddell started the car alongside Collins and took the lead into turn one on the first lap, building a four-second lead over the #64 Pontiac by lap 14. The car lost the class lead during the first caution period and never challenged for the lead again.
