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 useable entrances onto the track, located in turns 2 and 4.
