Thanks so much for the reply Billy, my car is not built yet so I have no idea what it will run. Ultimately I just want to enter the event and try and finish. The car will be built with lots of used parts and a budget of $10k Canadian ( $7200US ) sort of a back to basics project for a change.
So if it was you what class do you recommend for a first timer?
