the centre bore is slightly smaller so you'll want to ream out the hole on the wheel a bit or get some hubcentric VW spacers and file the outer hub down till it fits nice in the wheels. as they're ET49 you have lots of room for spacers, VW wheels can be as low as ET35 and even those can be spaced out a bit. main thing if you go spacers make sure they;'re deep enough to fit over the wheel hubs, the rears can be pretty deep I found 10mm spacers often wont fit over them
