I am looking to get 50mm H&R springs at the end of the month for my black edition a3. I have a feeling that if I drop it on these springs the alloys aren't going to fill out the arch and look a bit silly. So I'm trying to ascertain if spacers are going to make the stance look better so I can get it all done at the one time. I would also like to know what you would expect to pay for this sort of thing. My thoughts were 12mm rear and 10mm front with wheel arch mod. Any help at all would be great as I have no prior experience on this. Cheers
