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 Hoosier racing slick.

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.
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!
