In preparation for increasingly inclement weather I am working on winterising my A4. Step 1: Buy coilover and raise ride height (thanks to Hogg) Step 2: Buy winter wheels + winter tyres. Need some help on step 2 - think it would be prudent to get some smaller and thinner wheels. Found someone locally selling some 17" A3 wheels - 7.5 wide, ET56 (* suspected, but the alloys aren't OEM and aren't stamped, but were for a 2011 A3 2,0TDI which has ET56). My current wheels are ET40 and fit fine, but I've got S4 brake calipers on the front. My understanding is that they will fit a 17" wheel, but probably not one with an offset of 56. Do people concur, and if so - would it be a bad idea to get these wheels and use spacers? They're going cheap at with decent winter tyres on them. Any thoughts greatly appreciated.
