i have 19x8 with 235/35 tires 30mm offset. will these clear my a6 2.8 quattro as far as the upper control arms in the front? I know the stock offset is 35mm so, i just want to know if this should clear without any rubbing. i actually have the wheels on the car. i've driven it and can't really feel any rubbing. the people that installed it says that the inner tires are close to the upper control arms. should i get atleast a 5mm spacerjust to make sure?
