Late Models:
Whether it's an all aluminum open competition Late Model engine or a steel block WISSOTA or Nascar Late Model engine, Tim's Automotive can build and engine capable of putting you in winner's circle. Tim's Automotive specializes in Ford and Chevy engines and several of the region's top Late Model competitors use Ludwigson's powerplants, including Scott Gilberts, Darrell Nelson and Kerry Hanson.
WISSOTA Modifieds are sophisticated, high powered, open-wheeled race cars. As the name implies, they are radically "modified" from their stock status. The easiest way to identify a WISSOTA Modified is the lack of front fenders along with a spoiler on the rear of the car. You might also see the left front in the air, similar to the Late Models explained above. WISSOTA's Modified drivers may choose to run a 360 "Spec" engine that is not subject to a competitor's claim or a larger engine, up to 406 cubic inches, that is subject to certain claim procedures after each feature race. The chassis and suspension is very advanced and highly tuneable to meet the needs of the driver's style or track condition, and the vast majority of Modified racers in WISSOTA choose methanol rather than gasoline for a fuel.
Super Stocks:
WISSOTA Super Stocks appear, on the surface, similar to Late Models. The casual fan can tell the difference quickly by noticing the tires are much thinner, and Super Stocks do not have a spoiler on the rear deck of the car. Engine rules mandate a maximum of 360 cubic inches in the Super Stock division, and competitors in the class are limited to a 2 barrel carburetor. There are chassis limitations placed on competitors in the Super Stock division, so the cars are not as tuneable or exotic as those in the Late Model and Modified divisions. The division is known for parity and the competitors provide very entertaining competition for fans at many WISSOTA tracks.
Midwest Modifieds:
The WISSOTA Midwest Modifieds are a "limited" version of the Modifieds described above. The class was originally conceived and begun by a group of tracks in central and western Minnesota but the population of Midwest Modifieds has exploded since it became a WISSOTA sanctioned division. Although the chassis and suspension can be virtually identical to its big brother, the Midwest Modified division has a restricted package of engine rules and the body lines are a little more conservative than most of the full Modifieds in competition. It is intended to be a more affordable way for racers to get a taste for open wheeled racing and its continued growth at tracks in the region has been impressive.
