NASCAR to address hot temperatures at Michigan

NASCAR will make efforts to provide drivers and crew members with effective cooling and air conditioning for the coming race weekend at Michigan International Speedway. The weekend's action, featuring a Camping World Truck Series race on Saturday followed by the Sprint Cup Series on Sunday, is expected to be held under particularly hot temperatures, similar to those during the Cup races at New Hampshire and Indianapolis a few weeks ago. NASCAR wants the Michigan rules package, which Brad Keselowski discussed on Wednesday, to help cool the cars, which led to the installation of a dual outlet duct for all Cup cars this weekend. The new Michigan rules package is effectively the same as the Indianapolis package disregarding the latest changes to the package. In June, the Xfinity and Cup cars used what is regarded as the "standard" package for the 2015 season.
