These are new classes and as such the rules are being developed. Our goal with the spec class is to find a low cost entry class to get new racers interested in the onroad side of our sport.
The GT SS class is a step up from the spec class to allow for racers who want to go faster once they feel they are ready.
The Rally Open class is for those racers who have offroad buggies and want to try onroad for a reasonable price. A typical offroad buggy will need to change tires, install a front bumper under the body to help support the body and install a full body on the car. Roughly $100 to change a buggy over.
Qualifiers may be 5 minutes or more.
Mains may be 5 minutes or more.
