Default Grind backplate of wheel to reduce offset

Hey guys, I don't know if this is a crazy suggestion or what. I recently purchased new wheels and they are a bit aggressive and I'm getting some rubbing. I rolled the fenders and now only get occasional rubbing when its just me in the car, but bad rubbing with anyone in the back. The wheels need to tuck inside the fender just a tiny bit more.

Is it possible to grind down the back of the wheel, the plate where it mounts to the hub, to change the offset and pull the wheel inside the fender just a hair? I'm thinking 2-3mm. Would this reduce the structural integrity of the wheel? Am I insane or could this work?

Here are my details:
2006 GS 300AWD
Giovanna Dalar wheels
20x9 front 38 offset
20x10 rear 42 offset

Those are not aggresive at all, but pretty standard..Instead of shaving the back of the wheel how about you post your tire sizes first and we can go from there..By running a slightly smaller tire you can get the 2-3mm of clearance that you need..

OK, thanks. I figured that might be an option as well, but I don't really want to invest another $1500 in tires.

Current setup:
F 245/35/20
R 285/30/20

I need the overall diameter/circumference to be VERY close front to rear, as it is a GS AWD.

Thanks for your help!!!

Try tires first. Shaving the wheel sounds dangerous.

shaving the wheels is quite dangerous - the thickness of the wheel where the lug holds on gets thinner and is the most important part...

to me, personally, whats even more dangerous, is running those sizes on an AWD car... sounds like you're trying to find a reason to replace your center diff to me...

I dont know what tires your buying for $1500 but that is way to much..The rears sound like the problem.I would run a 275/30/20 or even a 265/35/
20 depending on what brand wheels you have..
