After many years of dedication of bringing Dirt sim racers everywhere a taste of what it’s like to get behind the wheel of a dirt sprint car, UDSRA will be making the transition into the dirt sim of the future, iRacing Dirt. With that being said we are proud to announce our partnership with PA Sprint Car Promotions for a 12 race track championship at the famed Williams Grove Speedway in Mechanicsburg, PA in the 410 wing sprint cars with 2 USAC showings on the card. Our main goal has not changed. We strive to create the most realistic sprint car simulation experience. These leagues will not be for the novice or rookie drivers, although everyone is invited to join us for the best Sim racing experience ever. We will have a strict set of rules to follow and will be enforced. UDSRA hopes you will choose us as your premiere home for your Dirt Sprint car sim racing.

UDSRA will now be a invitational league. Starting this coming Monday May 15th, 2017 @ 930 EST we will be hosting a practice/tryout race for drivers interested in applying to run with UDSRA. We are looking for respectable, clean racers who are looking for the “realistic sprint car experience”. If you are interested in running with UDSRA please apply at the link posted below.

Teamspeak will be required to race and drivers will need to be in teamspeak before race time in order to receive the pw for the race server. Teamspeak IP
