The Rolex Series Porsche teams endured a tough time in the two hour on Detroit's Belle Isle, several finding troubles around the tight street circuit.
The class was won by The Autohaus Motorsports Camaro duo of Jordan Taylor and Paul Edwards, trailed by the Speedsource Mazda and the Stevenson Camaro of Robin Liddell and John Edwards. The best of the Porsches trailed home in sixth position in class Magnus Racing's Andy Lally and John Potter – the Rolex 24 winners keeping in touch with Ferrari drivers Emil Assentato and Jeff Segal, leading the GT points championship.
“We walked away with solid points, so we’re happy with that,” Lally excepted. “To do well at a track like this, the Porsche would definitely need a few rule changes to be able to walk away with top finish, but at least we were the top Porsche. It was a great scrap with the guys we were racing with, and a really stacked field of talented drivers, so we’ll take it.”
Seventh in the GT drivers' points Leh Keen and Andrew Davis remain the next best placed Porsche squad in the standings for Brumos Racing despite a 13th place finish at the weekend after a loose wheel damaged the rear suspension on the no.59 entry.
Steve Bertheau and Spencer Pumpelly, part of TRG squad that split the Magnus and Brumos cars at Daytona in January also struggled. Bertheau was pushed into a spin by a Daytona Prototype in the early laps before the a deflating tyre delayed them further, dropping them to just a 15th place result.
The one spot from the two hour race came from the newest Porsche team in the Rolex Series.
Horton Autosport and driver Andrew Lindsey led a total of four laps, opting not to pit under one of the early caution periods to give themselves track position.
However, with the chasing cars now on new tyres Lindsey was soon shuffled back down the order as the grip ebbed away. Co-driver Eric Foss was then involved in an incident, and with the resultant additional pitstop fell to a tenth place finish.
