Corvette Racing: C6.R’s Subjected to IMSA Performance Adjustments

Corvette Racing: C6.R's Subjected to IMSA Performance Adjustments

The American Le Mans Series has announced their performance adjustments for the GT class ahead of next weekend’s race at Long Beach. The Corvette C6.Rs started the season with IMSA mandating a minimum weight of 1270 kg. That requirement added 25 kg to the Corvettes which equals roughly 60 pounds. IMSA has stated that the Pratt and Miller Corvettes will run with the extra weight until completion of Round 3 at Laguna Seca in May.

Both the Corvettes and the new Jaguar XKRS were subjected to the 25 kg weight penalty at Sebring, but Jaguar gets their penalty lifted for Long Beach and will also get to run with a larger restrictor to increase straight-line speed.

If you watched our video with Doug Fehan addressing the Corvette Corral tent at Sebring, he talked about how fast the BMWs looked during qualifying and that it would only be a matter of time before performance adjustments would be handed down to the E92 M3s. With a double-podium finish at Sebring, IMSA did just that and has required a 30 kg weight increase which brings the BMWs up to 1275 kg.

The Tequila Patron American Le Mans Series at Long Beach will be held on Saturday, April 17th. The one-hour, 40 minute race will start at 4:15 pm Pacific Time with the race being televised at 8:00 pm Eastern on SPEED.
