Are 8.5x19"/9.5x19" or 8.5x20"/10x20" rims going to be a problem on a '00 GS300??

I have a 1999 gs 300 with 20x9.5 in front and 20x10 in the rear with 1.5 lowering springs. some minor tweaks had to be done, I had to roll the lip in the rear fender and I had to cut some plastic in front to keep from rubbing from the sharp turns.
