What's the effect lowering springs will have on rubbing?

Long time no post here, as i had repurposed my 1er for daily driving. But, after a year off, my 1 is planned to be back in the autox circuit.

Over the weekend, i put Arc8 285/35 RS3s on the rear, with 255/35s on front. Initially, with a 5mm spacer on the rear, but the rubbing was out of control in the rear (fenders not rolled). While doing research on fender rolling, i decided instead to remove the 5mm spacers. That works fine, as long as your mount the tires while the springs are partially compressed, otherwise you cannot mount this fat a rear wheel/tire combo.

My question is, if i put on H&R Sport with Koni sports, which i have ready to install, will the car rubb more or less, given the suspension geometry?

I am pretty confident the answer is less rubbing against the fenders (from what i've read). Would i introduce more rubbing due to limited travel distance on the lower springs?
