If your going to simply split a factory wheel well your not getting all the advantages of a mini tub, the outer wheel well lwill limit the height and stance of the car, sure the tire width may be the same but to keep it from rubbing you have keep the car raised.
Although not a bolt in kit I had a Custom set made out of 16 gauge steel that resembled the factory profile that is only 32" front to rear, unlike the aftermarket ones that are around 20 gauge and 36" wide, so I can still use the rear seat but this elimated the dreaded outer wheel well roll So I can drop the car down lower. This is only true if you want to use the widest tire possible maximizing the entire space.
