apologies in advance if already covered somewhere, I tried searching and found a gazillion hits but none seem to actually have what I was after..

anyone know the lug bolt sizing for the new Tiguan? I assume they are the same across trim levels, but if not specifically the mk2 R-Lines with the 20" Misano wheels.
I am pretty sure they are M14x1.5 ball (not cone) seated bolts but not sure on the length to actually seat properly.

Also has anyone converted to lug nuts instead and if so what sizing of bolt?
