Mini tubs, advice, do's & don'ts?

I cut the whole tub out. I'll be using the factory inner and making a sheet metal outer so if I ever want to run a tall tire I'll still be able to keep the car as low as possible. View attachment 1715225270
looking back over these pics, if its a full rqace car, I`d use aftermarket inners, or make them square to fit ur square holes. I would try to keep it as close to stock looking on mine tho, like the other posters pics (rounded stock shape cut outs.) .
