The Cadillac DPi-V.R has been given a double break in performance ahead of next weekend’s Monterey SportsCar Championship powered by McLaren, with a power increase and weight decrease to the DPi contender.

Issued in a technical bulletin by IMSA on Friday, the Cadillacs will head to WeatherTech Raceway Laguna Seca with a 20 kg weight break and 0.3 mm larger air restrictor.

The restrictor change is estimated to provide a 1.6-horsepower increase.

A 2-liter increase in fuel capacity has also been given to the Dallara-built DPis, which have struggled in recent IMSA WeatherTech SportsCar Championship races to the Acura ARX-05 and Mazda RT24-Ps.

While the championship-leading Acura remains unchanged since Road America, the Mazda DPi has been given a 5 kg increase in minimum weight. 

Cadillac has not visited victory lane since the third round of the WeatherTech Championship season at Long Beach.

Acura Team Penske’s Dane Cameron and Juan Pablo Montoya enter the penultimate round of the season with a seven-point lead over the Action Express Racing-run Wheelen Engineering Racing Cadillac DPi of Felipe Nasr and Pipo Derani. 

Mazda’s Jonathan Bomarito, along with the Penske duo of Ricky Taylor and Helio Castroneves are ten points further back, tied for third in the DPi points standings.

Weight Changes Made to Half of GTD Field

No BoP changes, meanwhile, have been declared for the GT Le Mans class, although four out of the eight GT3 cars taking part in next weekend’s race in the GT Daytona class have undergone weight adjustments.

The Porsche 911 GT3 R is the biggest hit, with a 20 kg increase, while the Lexus RC F GT3 gets a 5 kg addition in minimum weight.

Both the Lamborghini Huracan GT3 Evo and McLaren 720S GT3, meanwhile, have 10 kg weight breaks heading into the two-hour and 40-minute race.
