Hi all.......upgrading my alloys on S4 from 18" oem to 19" RS4 S-lines...... Will need spacers to deal with offset differences.....May need up to 8mm to ensure rims clear inside suspension strut......Any body ever used spacers as big as 8mm......??? Any issues to be aware of......??? Will I need new longer bolts for the alloys.....and if so are they easy to come by........??? I know lots of questions so any friendly advise really really appreciated.......:thumbsup:
