Uggggg! Why doesn't VW stick with 5 x 100? That's what I had on my B4 but now that I am in the 5.5 I must change everything because of a 2 mm difference?! Someone please tell me that there is little to no different between 5 x 100 and 5 x 112 so I can just go ahead and use the spacers that I have. And to confirm, ball seating is used on the stock wheels?
