Anyone thats known me for a while knows I will get that 225/35/20 under it, (I also could drop to a 30 series if need be)I own a sawzall, and will cut, bend, or break as needed. I never see 20"s on Passats, I know there is a reason, Its not supposed to fit... It wont be easy...but if it was everyone would do it.
BTW, My jetta had to be "modded" to fit the 20"s...
