Hi all.. Just after a bit of advice with wheels. My bro has a MK4 golf, and wants to upgrade the wheels. Thing is, i'm not really sure what size he needs (5.5J and that sort of number...!!)? He dont want to spend a huge amount (who doesnt

)and doesnt want any work done on the arches, so i guess 16 inch max? Or can you go to 17 with a MK4??
Finally, can anyone recommend any good places to get such wheels?
Many thanks
