Bristol Motor Speedway is adding traction compound to the lower groove for the race today. The resin will increase grip for the NASCAR Cup race, rescheduled for 1:07 p.m. ET today after heavy rains Sunday. The question will be whether it will be faster than the upper groove -- and how much the grooves will change throughout the 500-lap event.

The squeaky wheel finding its groove: Track officials are running a machine that grinds tire rubber into the track this morning at Bristol Motor Speedway. They are attempting to make the bottom lane the preferred lane at Bristol or at least as good as the top lane. The race, rescheduled from Sunday because of rain, is set for a 1:07 p.m. ET green flag today.

Rain has postponed the NASCAR Cup race Sunday at Bristol Motor Speedway to 1 p.m. ET Monday. With a forecast of rain throughout the day, NASCAR decided to make the decision more than two hours before the scheduled start of the race, telling the drivers at their prerace meeting that they won't try to wait it out. NASCAR would need at least a three-hour window – and possibly more thanks to cool temperatures and the heavy rains – to dry the track and get at least 250 laps of the 500 scheduled completed for an official race. The forecast is for a 30 to 50 percent chance of rain throughout Monday afternoon.

Kyle Larson isn't too big of a fan of the width of the adhesive substance (referred to as VHT) that Bristol Motor Speedway officials have put down in the lower groove. He feels they almost gave the drivers too much grip. Larson, on the pole for the race Sunday as the field was set by the standings because of rain Friday, explains what he felt during practice:
