GreenGoblin's "Green Goblin" - 2004 Infiniti G35 Coupe

I am new to the forum and wanted to ask you a few questions about your flush rims on sale. I was wonder if you were experiencing any rubbing issues in the rear or in the front? How much camber do you have in the front and in the rear? Do you rub in the front while making a U-turn and did you do any modifications to the front fender well? The reason why I'm asking is because I'm currently talking to a vendor about custom wheels and he is recommending that I go with 20x9.5 (3inch lip with 255/30/20 tires) and 20x11 (4.5 inchh lip with 295/25/20). He suggested that I go with the aggressive look and he stated, " Keep in mind these fitments are 0.5" more aggressive then our normal fitments on these cars. These fitments will require some body adjustments ex.... rolled fenders and from 1.5 - 2 degrees of negative camber." Normal fitment which he described was flush with the fender. The Vendor is D2Forged. I wasn't sure if I was going to have any rubbing issues in either the front or rear with his recommendation and whether or not it will stick out to far from the fender. Whether I would have rim issues with the tire selection also? A friend of min told me that with those recommended tires sizes that I may run the risk of damaging the inner rim if I hit a small pot hole with those camber settings? Your suggestion would be very much appreciated. Thanks
