I'm currently running 225/50/16 tires on 16x7 wheels, probably 30-40mm offset:

with the ground control coilover sleeves raised up to the max height setting and 1.6 degrees of camber, shocks set to 5 (stiffest) and I'm still getting light rubbing under hard cornering. My fenders were rolled in by a performance shop and I've removed the plastic inner fender liners.

Will running more camber reduce the rubbing? Or do I need to get the fenders rolled out?

I was previously running 205s and after the fender roll the rubbing was gone. Comments/advice?

 

Where is it rubbing?

Does it rub at full steering lock?

I doubt the offset is in the 30's.
7.0", +30 to +35 should have no problems with that tire size.
I've run 7.0", +32 with 225 / 50 / 16 Bridgestone S-03 Pole Positions with no rubbing.

Are you running modified steering?
Shims on the tie rod ends?

It rubs right where the tire goes under the fender, I guess right in the middle of the fender. I can run my hand under the lip of the fender and see tire debris after a hard drive. I hear it when I'm going through a high speed slalom type course right as I turn the wheel quickly and the weight shifts to the outside wheel. Driving normal speeds at full lock it doesn't rub but I haven't checked by compressing the suspension with the wheel at full lock, thats a good idea. No steering modifications and stock tie rods.

 

roll the fenders yourself
