tubbed is when you want to put a really large tire under a car you cut out the wheel houses and parts of the floor to accomidate the large wheels. Camaros are unibody so usually you are also cutting out the part of the floor that incorporates the frame. Then some new Iron is usually to tied subframe connectors that now hold the rear suspension. Basically you are cutting out most of the floor in the back half of the car.
