Sunset Speedway, Innisifil, Canada - Racetracks on Waymarking.com

Sunset speedway is open from mid May to mid October racing weekly on Saturdays evenings. 

Racing is held regularly in the following four classes

The Sunset Late Models are Sunset's fastest regular class. They are minimum 105" wheelbase, tube frame chassis race cars powered by purpose-built V8 motors.  Motors are typically 9.5 : 1 compression ratio, although 10 : 1 is allowed with a weight penalty.  Underslung chassis are allowed. The bodies are made from sheet metal, fibreglass or aluminum, and are styled after North American production vehicles. These cars have highly adjustable chassis, and run a grooved Goodyear racing tire.

Sunset's Thunder Cars are highly competitive rear wheel drive North American racing machines. They are V6 or V8 powered (as stock for its particular chassis), with few modifications allowed to the drivetrain. The chassis are also very close to stock, and ride on a specialized racing tire. Most teams opt for GM chassis and drivetrain, but some Ford and Dodge powered cars also compete. For 2004, compact trucks are now legal chassis types to use in this class. These restrictions keep this class very close and competitive, often culminating to a close points chase through the entire season.

The Four Cylinder class has developed into one of the most action-packed. The series is open to any four cylinder passenger car (with some exceptions) with a displacement of no more than 2500CC and a wheelbase of no more than 104". Multi valve motors are allowed, but a weight penalty is applied for engines with more than 2 valves per cylinder. Normal street tires are used, and very few modifications are allowed to drivetrain or chassis.  This class grows larger every year - low cost and a wide choice of competitive cars makes this series a lot of fun to drive in as well. Three, four and even five wide racing is not uncommon, making this an exciting class to watch too.

The "Four Fun" class was introduced in 2004. It is a strictly-for-stock strictly-for-fun entry level series, consisting of automatic transmission driven (with some exceptions) vehicles powered by up to four cylinders. A specific list of eligible vehicles is detailed in the rulebook. There also is a $700.00 claimer rule, which will help keep the costs to an absolute minimum. It should also be noted that it is not necessary for these vehicles to be hauled to and from the track each week - storage is available in the pits for regular registered cars throughout
the season with "work time" every Wednesday during the regularly scheduled practice sessions. All these features make this an incredibly affordable and fun class to race in!
