6/4/2016With safety and comfortability of both racers and officials, heat races will just be a 4 car invert for now. With limited cars and new teams coming out, it's best for now to simply take the fastest 8 out of qualifying and divide and invert them. Everyone is making the A at this point, but for starts and everything else right now IRA feels it best to make this adjustment beginning June 4th and until further notice. Thanks, Steve
