No Change for Corvette C7.Rs in New Round of IMSA BoP Adjustments


No Change for Corvette C7.Rs in New Round of IMSA BoP Adjustments

IMSA has made yet more changes to the Balance of Performance (BoP) tables for the GT Le Mans class ahead of the next weekend’s race at Northeast Grand Prix at Lime Rock according to

While the Corvette Racing C7.Rs are unaffected by these new adjustments, Ferrari gets a boost while BMW and Porsche will be slowed.

In recent weeks, the Porsche 911 RSR has struggled to maintain pace with the rest of the GT Le Mans class, so it’s a surprise (for us) to see that they are receiving 20kg of additional weight. This could be in light of a coming tire change as the Porsche 911s have not had good results with the new Michelin WEC-spec tires that the GT Le Mans class switched to at Laguna Seca in May.

BMW’s M6 has had their turbo boost reduced while the Ferrari 488 GTE will be given a slight increase for their turbo boost. The BMW will have their fuel capacity reduced by -2 liters while the Ferrari gains +2 liters. However, the Ferrari will receive a 1.0mm larger refueling restrictor as well.

The only change to the Ford GTs will be a 0.1mm reduction in their refueling restrictors.

The Ford GTs have won the last three straight races but Corvette Racing’s Tommy Milner and Oliver Gavin still lead the GT Le Mans Drivers Championship by five points over Richard Westbrook and Ryan Briscoe. The No.4 Corvette C7.R is leading the Team Championship by five points over the No. 67 Ford GT and Chevrolet leads Ford by 7 points in the Manufacturers Championship.

The next race is the IMSA WeatherTech Northeast Grand Prix on the 1.5 mile bullring known at Lime Rock. The green flag drops at 3:05 pm ET on Saturday, July 23rd.
