The pair of Team Penske Acura ARX-05s have been hit with an increase in minimum weight ahead of next weekend’s Sahlen’s Six Hours of The Glen.

Confirmed in the latest Balance of Performance issued by IMSA, the Mid-Ohio and Detroit-winning DPi car will be 15 kg heavier for the sixth round of the IMSA WeatherTech SportsCar Championship season.

It brings the Acura DPi’s weight up to 935 kg, on par with the Nissan DPi, which remains unchanged other than the allowance of a new front wheel arch wicker aero option.

Additionally, the Acura DPi has been handed a 1-liter reduction in fuel capacity.

No other BoP changes have been made the class.

While the No. 31 Whelen Engineering Racing Cadillac DPi-V.R duo of Pipo Derani and Felipe Nasr continue to lead the championship, the Team Penske pairings of Dane Cameron/Juan Pablo Montoya and Helio Castroneves/Ricky Taylor have closed to within 5 and 6 points, respectively.

McLaren Gets Power Increase, Weight Break

As expected, the McLaren 720S GT3 has been given a significant performance break, with the car shedding 25 kg of weight and having increased turbo boost levels across all RPM levels, equating roughly to 14 horsepower.

While effective for Watkins Glen, the changes will only be seen for the following round at Canadian Tire Motorsport Park, as Compass Racing is entered for the WeatherTech Sprint Cup rounds-only.

IMSA, meanwhile, has clarified the minimum ground clearance for cars in GT Le Mans, following its initial issuing of the BoP for the class last month that has seen the BMW M8 GTEs receive a power boost in the range of 12 horsepower.
