Guys i need some help and urgently. I tried reading through the forums but am having trouble finding a set up like mine. I ordered a set of 18" flat?fat fives for my b5 a4 quattro (prefacelift) which is currently running on bilstein pss9's(adjustable dampening and height). I need help figuring out which spacer would make the rim and tire sit flush with the fender. The rim has a e.t. of 45. I also ordered 225/40/18 Continental tires to match the rim. Please help me figure it out so that i can order some h&r ones of ecs. I'm hoping to get as flush as possible without having to roll the fenders. Thanks

Lazer viking ran 15mm up front and 20mm in back but he was using 205/40/18 iirc and therefore i might something different.
