I have 20mm spacers on all 4 of my factory 21's and lowered. Mine rub when backing up and cranking the wheel in the same place as yours. Everyone with spacers has the same issue so I suspect your aftermarket rims have a 20mm+ offset on top of the factory offset. I used a wire wheel to grind down the finns on the wheel liner to minimize/eliminate the rubbing.
