Most say that the bolt patter/PCD is 4x108, but this guy claims that the Thai Fiesta has a bolt pattern/PCD thats 4x100.

PCD of 100 is about 10cm, PCD of 108 is 10.8cm, so its should be almost 11cm if the PCD is 108.
@dannyhilton, as an owner of a German Fiesta WS, what do you think?
Same PCD or different?
