Southern Illinois Raceway

Southern Illinois Raceway (SIR) is a quick, high-banked 1/8th mile clay oval most often seeing lap times in the 9 - 11 second range. The popular raceway is located approximately 5 miles east of Marion, Illinois on Highway 13.  The track is completely wrapped with a high, well-supported catch fence atop a strong guardrail.  It is known for becoming a slick surface from the infield tires all the way up to a fast cushion, right around the outside wall, creating the perfect conditions for lap-after-lap slidejobs and constant 3-wide battles.

It has two usable entrances onto the track, located in turns 2 and 4, as well as an exit in turn 1. The exit, however, is able to be sealed seamlessly by an additional section of guardrail during races to prevent dangerous wrecks common to track exits that are placed in the entries of turns.
