E46 wheelwell rub?

[bms325ci]

I have a 2002 325ci. I have Hamann HM2's in the rear 19x10. I had the wheelwell's rolled when they were put on, but i still get a quick rub noise in the wheelwell if there's anyone in my backseat or if i hit a decent bump. The car is not lowered, but i wanna but H&R coilovers in it. Not sure if i should bother if i can't drop it any lower because of this rubbing. It seems to hit this little nub in the wheelwell but not sure?
Anybody with any info?

Not much you can do except try rolling the fenders even more.

Also, what size tires are you running? (make and size) That has an effect on rubbing as well since different tires have different sidewall shapes.
