Yeah forget going 11" on the rears.
I ordered a set of these in from 101tires.com 8.5x19 front 10x19 rear. I'm planning to run 5mm spacers both front and rear. Max Performance Summer Tires 235/35ZR19 front and 275/30ZR19 rear.
I was curious as to how 19" wheels would look, sweeeeet. I don't care for the other crud added to this car though lol.
