ah i see. its not a difficult thing to do. just get the hubs off, get them cross drilled....infact, its actually easier to phone the manufacturer of the wheels and ask them to send u a set of 'blanks' (the wheels without them drilled at all) and get a machine shop to drill them to 4x108 for u mate. Most manufacturers wont have a problem with this at all (from experience....i sell alloys for a living)
