hello there guys I, after some advice about amg wheels on a Passat ive had a look at some wheels today they were 15 inch Mercedes monoblock alloys genuine amg wheels however the lug holes were for a m12 and I kno the passats are m14. I was also after some 17 inch staggered fit clk slk amgs also and was wondering are they are m12 or are some of them m14 sets aswell. Anybody who has had them before if you can help out many thanks
