I recently purchased a Miata that has an aftermarket exhaust, Pilot sport 4's with everything else stock. Just to streamline it what class would be best? While keeping it competitive and fair.
I will be looking forward jumping back into Autocross after a 4 year hiatus. With also the interest of doing time trials & Volunteering again within the area.
