Phoenix Raceway will have the PJ1 traction compound again applied to the track for next month’s races. That event marks the debut of the short track package for Cup that is intended to tighten the racing.
The traction compound will be applied in the corners but will be applied more along the driving line. Last fall, the traction compound was applied close to the wall. It will not be as high this time in the turns.
