IMSA has released the Balance of Performance table for next weekend’s Chevrolet Sports Car Classic at Detroit, with the Cadillac DPi-V.Rs receiving their third weight adjustment in as many races.
The increase of 15 kg comes after the Dallara-based Cadillacs were given a 10 kg minimum weight reduction for the most recent IMSA WeatherTech SportsCar Championship round at Mid-Ohio.
The BoP update released on Thursday shows the Cadillacs at 960 kg, the heaviest they have been this season, while the other parameters in the DPi class are unchanged.
After having their minimum weight value raised to 955 kg for round four at WeatherTech Raceway Laguna Seca, IMSA returned the Cadillacs to 945 kg for Mid-Ohio.
The General Motors brand has not won a race since round three at Long Beach, while Acura arrives into the sixth round of the campaign with the momentum of back-to-back victories for Wayne Taylor Racing’s Filipe Albuquerque and Ricky Taylor.
The Acura ARX-05s have been racing at 920 kg since receiving a 10 kg reduction ahead of the Acura Grand Prix of Long Beach.
The other BoP change for Detroit is a 10 kg weight increase for the BMW M4 GT3s that are competing in the GT Daytona class.
This brings the cars from Turner Motorsport and Paul Miller Racing up to 1305 kg.
Turner drivers Bill Auberlen and Robby Foley won the previous race at Mid-Ohio following a post-race tech infringement for the Inception Racing McLaren squad.
