You dont have to have aero even, as long as you have a complete car, you can keep it stock body. I did that for 5/7 nopi events after their rule cost me my front kit in round 2. It was ugly, but it kept me driving.
*Their rule was ADDED mid-event that I must have a front end, and mine had already broken once that day, so it fell off rather easily. They added it cuz some guy busted a oil cooler on a Nopi triple stacker cone and they had no kitty litter to clean it so it 'took
too long' and so they made the rule.
