IF there is a turbo'd Impreza in STS, he should be in Street Mod. IF there is a WRX in STS, he should be in STX. These are things you need to take to the orginizers of your local events, along with your rulebook to show them the correct classes for the vehicles. Be upfront about this with the other competitors, they might not know the rules and that they are classified wrong. Being honest and friendly go a LONG way to not making this an unpleasant situation.
