NASCAR Late Models

The Weekly Warriors of the NASCAR Late Models make up our premier weekly division as they compete for Illinois and National NASCAR fame and honors. A multitude of Champions and challengers call Rockford home and continuously find themselves in the middle of the excitement under the lights on Saturday nights. This class typically sees 450-475 horsepower engines on the 8″ Hoosier D-800 compound tire with fabricated chassis, total weight is in the 2825 pound vicinity. The 10.8 to 1 compression cast iron production engine platform is the basis of the class, with a maximum cubic inch allowance of 362. Newer technology including the 5.3 liter LS motor and General Motors ‘604’ crate have become popular combinations as well, with all three engine platforms collecting wins

All American Sporstmen

The Sportsmen class car is an eight-cylinder stock car based on stock production compact cars. The class consists of any 1960 or newer American made passenger cars. All cars have been modified for driver protection (roll cage, racing seat and belts, fuel cell, etc.). The chassis is predominately stock. The engines are limited to 362 cubic inches,flat top pistons, stock heads, and limited cam lift or commonly used crate motors (a motor directly from GM) . These cars compete on the Hoosier D-800 tire. Sportsmen cars are the quickest division after the Late Models with the fastest times hovering below 15 seconds on the quarter mile. This class has proven to be popular with good car counts and close racing and those seeking to learn how to set up a car so as to advance into the Late Model division.

American Short Trackers

American Short Trackers are a 1994 and older American produced 94” to 103” stock wheelbase 4-cylinder car, most commonly used Ford Mustangs they are a fast paced action packed division to watch, previous NASCAR driver Travis Kvapil got his start in one right here at Rockford Speedway and many multi time champions have made this class so competitive over the years names such as Brett McCoy, George Sparkman to name a few.

RoadRunners

The Roadrunner car is an eight-cylinder stock car based on stock production cars. In an effort to revitalize this division. All cars have been modified for driver protections (roll cages, racing seat and belts, fuel cells, etc.) The chassis is absolutely stock. The engines are limited to 360 cubic inches and 9.1 compression. This division competes on Hoosier 850 tires. The racing is extraordinarily competitive and a few of these drivers have progressed to the more sophisticated divisions.

Bandits

These four cylinder machines are ultra competitive, with the front wheel drive cars lifting their back tires off the racing surface as they speed through the corners. A wide variety of car name plates make up the field each race night with domestic and foreign name plates, many models which you still see on the roads today. A wide variety of stock production engines ranging from 1.8 to 2.5 liters can be found under the hoods of these stock production frames. With limited ‘for racing’ changes allowed, coupled with DOT tires, the Bandits provide plenty of excitement.

Original Sixers

This is the entry Level division at Rockford Speedway. Based on 2010 and older, stock production, front wheel drive V-6 sedans, this is a throwback class that essentially allows one to remove the glass, chain the doors, acquire safety equipment and hit the banks of Rockford Speedway. With domestic vehicles being the only cars allowed, Chevrolets, Fords, Pontiacs, Dodges and Oldsmobiles fill the track as drivers transition from watching in the grandstands to getting their first taste of racing competition. Completely stock engines with a maximum of 3.8 liters sets the tone as few modifications are allowed at all, even the DOT tires are required to be older. A $450 Claim Rule allows the track to purchase a complete running car at any time, helping to keep the cost down and the level of FUN high.
