Wheel spacers on 2.0 TDi Sport??
Would like to fit a set of spacers to my 2.0 TDi sport which is fitted with a set of genuine 18" S-Line RS6 style alloys, and is lowered on -50mm H&R springs. Need a bit of help/advice though as to which ones I need and where to get them from 
Firstly, what size spacers are the ideal ones to have with my setup? (what is the maximum width I can get away with without causing rubbing issues ect..??)
And secondly, where is the best/cheapest place to get the spacers and new wheel bolts from and how much will I be looking at to do all 4 corners?
Any pics of your cars with spacers fitted would be gratefully received and may help me decide what width spacers I need
