Unless you intend to make your street driven car == a race car, you will regret removing the inner fenders.
Basically by removing the inner fenders, you are removing some of the structural integrity of the car.
If you ever decide to sell this car without the inner fenders in place, the first thought a buyer will have is that your car has been extensively raced.
In any event, you lose when you remove inner fenders on a Mopar.
