NASCAR confirmed Monday that the PJ1 traction compound will be applied in all four corners at Michigan International Speedway for this weekend’s Cup and Gander Outdoors Truck Series races.
It will mark the first time the track has applied a traction compound.
NASCAR stated to NBC Sports that the traction compound will be applied to the top 40 feet in the corners.
The move comes after the June race at Michigan did not produce all the desired results with the racing.
