Default how to fix rubbing issues with 20's

Hey guys I need help from everyone, just purchase a set of Gunmeatl w/chrome lip iForged wheels for my white IS350.
Bolt pattern 5x114.3, 20x8.5 fr 2" lip, 20x10.5 rr. 4.25" lip. 245/35/20 fr, 275/30/20 rr. Barely clear the BBK with 15mm spacer in the front.
Offsets are unknown because iForged doesn't release it. I love these wheels but the problem is it's rubbing in the front and the rear. It rub when there is a little bump on the road or when I make a fast turn. Just by eyeballing it I don't think rolling my fenders would even help because the wheels are too wide or is it? What are my options? Is there a way to make this work. Keep in mind the car is not lowered. Or should I just sell it and take a loss?

yes, downsize your tires...rolling your fenders will always work too.

I have the same size rim in front and I had 245/35/20 with no drop and I also had heated my wheel well with a heat gun to push back some of the trouble spots. Still rubbed and just didnt feel safe to me. I hate to say it but at least on the front your going to need a smaller tire I went with 225/35/20. IDK about your back wheels seeing as I have 20x8.5 wheels all the way around.

Without a doubt, downsize the tires. I have 20x8.5s all the way around. I just changed my front tires to 245/30s and they rub the top of the fender when going over bumps. I have 255/30s in the rear and don't have any rubbing issues at all. I am also lowered an inch in the rear and .8 of an inch in the front. For the front, I am going to switch to 235/30 which will give me 3 more milimeters in overall height which is all I need because the rubbing is not bad and only when going over 15 mph over bumps.

so you guys are telling me aint no way it'll work with the 275/30/20 in the rear. Keep in mind it is 20x10.5 in the rear. If I go 265/30/20 and roll the fenders will I pull it off? Rolling the fenders is the last resort if I dont have to that'll even be better. And what if I go 235/30/20 in the front?

275/30 in the rear is fine, the 245/35 is your prob up front....you need 245/30 or 235/30. Everyone i know with a 3GS or 2IS runs a 275/30 in the rear

I agree that 275/30 can work in the rear, but the OP says he is rubbing on the fender. This means his offset is the problem. For the front, 235/30 should be fine regardless of the offset.

You're on the money AZ, I believe my offset is wrong. iForged didn't tell me the offsets but was told it should be fine. So now thinking about puttin 265/30/20 in the rear plus roll the fenders. As for the fronts I'll just get 235/30/20, what you guys think?
