Yeah, it's possible. Do you plan on widening your wheel situation too?

 

 

I've wanted to do this for the same reason although I don't think I want to buy wider wheels. I just want to cover up the rust. Can't wait to see how this turns out if you do it. I've been planning to try and sand/bondo/paint mine just to try and slow down the spread of the rust.

 

 

Spacers might help you get your fitment to where you want to be. I know the G37 18s and 19s need spacers for proper fitment on a G35 so they may be needed for 370 wheels as well. If you put arches on it, at least cut out the rust before covering it all up again.

 

 

Not exactly the same as what you are talking about but if you look at this image @Ichiglo_ you'll see how the rear flares are cut. If you cut too much off of the body (I don't know how rusted your car is), you might not be able to attach them as low as in the picture with the bronze car.

@jbarnett250 if you aren't going wider or at least spacing out the wheels it will probably look quite bad

 

 

 

@Ichiglo_ it doesn't seem very bad. personally I would have that surface rust cleaned up and repainted instead of the flares

 

 

Are you paying someone to install the fender flares? I think you'll end up paying the same amount to have it professionally done.

 

 

Ichiglo you're taking it to body shops that don't want to touch rust repair work, they make a lot more money doing insurance claims on newer cars which always involve the most expensive route in order to get the car back to "perfect". They don't want to work on an old car with an owner trying to save as much $$ as possible.

That rust really isn't bad at all compared to what I had.
Have you tried checking Craigslist and asking around on local car enthusiast Facebook pages to find a smaller shop or a body guy willing to repair your current quarter panel off the clock, without all of the roadblocks that get put in place when dealing with a larger business? They could repair the rust either with metal or waterproof fiberglass filler and roll your stock fenders at the same time. Have them also drill capped holes in the inner wheel well to make filling the QP with fluid film really easy.

The spacers are both to clear the Brembo brakes on the performance package coupes and to avoid the horrible "sunken in" look you get from running the wrong offset wheels with no spacers. IDK the exact size but I believe mine are 2_ mm in the back and 1_ mm in the front.
