The Mini Stock car is built using a production chassis. Most cars use a Mustang. The bodies are 100% stock appearing. These cars have very limited adjustability using stock suspension components. These cars run a 4 cylinder engine with a cast iron head and a hydraulic camshaft. Mini Stock cars weigh 2300lbs and run a 2 barrel carburetor and a 7 inch racing tire. This is designed to be an affordable entry/semi advanced class.
