yes they will fit dont worry about off set,but if they dont go over the center hub flange like some vauxhalls dont
check to see if they is a steel hub ring pressed in the rim on the inside,if so knock it out from the outside in and then it will fit.
exactly the same as my mx5 on my k11, too small a bore. The best way is to get the centre bored out or if your on a budget a dremil. Your also need speacial wheel nuts.
