Safe to Remove Inner Fenders?

If you are removing to replace, then do one side at a time and you shouldnt lose too much alignment. Just make sure to measure before you start cutting, and again before you start welding. Having the car on stands, t-bars backed off etc will help.

Not a street friendly mod! You WILL overheat with those two big fans (tires) blowing air forward. Not to mention the rocks they will fire at your radiator like bullets. Also since the top of the fender bolts to the inner fender, you will need to fab some sort of rail to keep things in place or things will go out of alignment really fast.
