I have a similar setup. 19x9 +25 & 19x10.5 +15 with stock sport tires & no camber kit for the front. I'm also dropped moderately on KW V3s and I only rub against the plastic cover during a very spirited driving. Normal driving = no rubbing. GL with your purchase.
p.s. I might be selling my RZ-DFs soon. LMK if you're interested.
