Beginning this weekend, you can upgrade your race day by purchasing unique event access right from your phone.  Sonoma Raceway has partnered with mobile technology company Experience (expapp.com) to let race fans personalize their race days and gain behind the scenes access.

Upgrade experiences that will be available include the Garage/Pit/Pre-race Pass, which will let you experience the garage all weekend and gain access to the pits up to one half hour prior to the green flag.  It will also include Garage Passes, which will let fans explore the INDYCAR garage, sneak a glimpse of their favorite driver and take photos of the teams and their equipment up close.
