IMSA late Friday issued Balance of Performance adjustments ahead of next weekend’s Mobil 1 Sportscar Grand Prix at Canadian Tire Motorsport Park.

The Ford EcoBoost-powered Rileys have been given a 0.4 mm larger air restrictor for the upcoming TUDOR United SportsCar Championship round, as well as a to-be-announced change in turbo boost pressure.

No adjustments have been made to any other cars or engines in the Prototype class, which effectively leaves the much talked about P2/DP balance unchanged from the most recent round at Watkins Glen.

GT Daytona competitors are also left relatively unaltered, except for the BMW Z4 GT3, which has been given a 30 kg weight increase.

Additionally, the Aston Martin Vantage GT3 must now run the DP specification Crawford rear wing.

No changes have been released for GT Le Mans cars.
