IMCA Releases 2019 Rules For Six Of Eight Divisions
Image
The 2019 rules for six of IMCA’s eight divisions have been announced including Modifieds, Northern SportMods, Southern SportMods, stock cars, Hobby Stocks and Sport Compact.
“While minimal, the changes or clarifications we’ve made in rules for 2019 are an effort to head off the direction some of our divisions are headed, such as suspension or aerodynamics,” IMCA President Brett Root said.
Maximum and minimum free-standing spring heights are specified for front and rear suspensions for Modifieds and both SportMod divisions, and the nose piece must be the same width from front to back.
“We want to keep the open wheeled look of all these divisions,” Root said. “We have done that with the nose rules.”
Maximum and minimum roof dimensions will include the sides when Modifieds, Northern SportMods and Southern SportMods are measured in tech. No bends or breaks will be allowed in sail panels for any of those divisions.
Modified and Northern SportMod roofs must be mounted within half an inch of the rear roll cage. Modified drivers competing with a 604-cubic-inch crate engine must also use one of two carburetor spacers, the Speedway Motors part no. 545-64940 or the Moroso part no. 64940.
Southern SportMod drivers competing with a manual transmission must now utilize a cast iron three-speed OEM manual transmission; no four- or five-speed transmissions are allowed in the division. GM 602-cubic-inch crate engines manufactured after December 2017 with Chevy Cap seals must have IMCA Cable-Lok Seals.
Stock cars must have an OEM appearing aftermarket plastic nose piece with a minimum eight inch ground clearance and also have specified front and rear spring heights.
Hobby Stock nose pieces must have a minimum nine-inch ground clearance. There’s a maximum 31-inch measurement from the back of the engine block to the front edge of the GM Metric roof.
The Hobby Stock front OEM fire wall may be replaced with a steel fabricated firewall. The front firewall must be vertical, 24 to 26 inches tall, and located no farther back than the rear of the oval frame hole. Fire walls must extend to the body.
For the Sport Compact class, all engines must use maximum two-inch OD exhaust pipes. There will also be no strut boots, covers or bump stops allowed.
IMCA Late Model and IMCA RaceSaver Sprint Car rules will be announced at a later date.
