The Ontario Stock Car Association of Asphalt Racers, usually shortened to the acronym OSCAAR, is a Canadian stock car racing series featuring three divisions, Open Wheeled Modifieds, Hot Rods and Pro Sprint.

[2] Previously the series included an Outlaw Super Late Models division.

The OSCAAR Hot Rod Series is for vintage-bodied cars with crate engines and modern running gear.

Each car weighs 450 lbs, run one inch off the ground and can reach upwards of 100 mph.

The cars consisted of a low-cut, flat-sided late model chassis that were offset to the drivers side for better cornering on oval tracks and allowed the greatest horsepower of any Ontario stock car division.
