The Mk4 uses a different fitment. What you can fit is the Mk3.5 Cabrio (the one which has a Mk4 front end but is basically a Mk3) wheel. These are like the Mk4 wheels but have Mk3 fitment. The only trouble is they are relatively rare, and cost a lot from VW, but they fit straight on and the airbag should, I believe, plug straight in.
just wondering if the cabrio wheel would fit a mkIV polo also? i suspect it would. also, how much do you reckon it would cost to get a second hand one from a scrappy (although it may be hard to find one that hasn't gone off)?
well the south african mk1 citigolfs have what looks like the mk4 steering wheels on them so it must be possible to fi to most of the models, it may be aorth aving a word...somehow
