Class Information

The TRAC (The Road-Racers of Atlantic Canada) Race Series

runs five distinct sedan series at each event — the Grand Touring (GT) Debert Race series, the Grand Touring (GT) Pennfield Race series, the Spec Miata series, the Atlantic Challenge 1 hour Enduro series, and Unlimited series — and an Open Wheel series, featuring Formula-type cars.

Grand Touring (GT) Debert and Pennfield races are 15 laps, and awards are given in each class — GT1, GT2, GT3, GT4, GT5, and GT6 for the top finishers.

Spec Miata is a series consisting of only Mazda Miatas, with a specific set of allowed modifications to ensure they are closely matched. Spec Miatas run sprint races toward the Spec Miata Championship. When there are not enough cars to make a minimum class (3) the Spec Miatas will run with the GT cars.

Atlantic Challenge Enduro races are one hour long each (including a five minute mandatory pit stop), with cars in all sedan classes and Spec Miata running. Awards are given for each class in this series.

Unlimited Series races for GT class cars are 15 laps, and in these races, class doesn’t matter. Awards are given for best overall finishers, regardless of their class.

Open Wheel races are 15 laps each, and awards are given to top finishers in each formula class (see below).


GT1/ProStock: 1m, 10.999 or faster (all high hp tube frame cars or production based cars with power to weight below 6lbs per hp)

GT2: 1m, 11.000 and slower

GT3: 1m, 14.000 and slower

GT4: 1m, 17.000 and slower

GT5: 1m, 19.000 and slower

Spec Miata: Spec Miatas are Mazda Miatas that have a specific set of modifications that are allowed to ensure all cars are very closely matched. This is an affordable class to get into, and there are many resources available due to its popularity. Spec Miatas are also eligible to race in GT5 class.

Open Wheel: Open Wheel classes are split into Formula Ford 1600 (FF), which includes all Ford 1600 powered open wheel cars (with limited engine modification), and Formula Libre (FL) which is a catch-all class for other open wheel cars 2.0L of displacement and under, and those with extensive modification.
