Due to the number of threads recently about people asking about wheel offsets and fitments, and not being able to understand them, I have made this idiots guide.   For all you people who are about to post up on this thread giving all this indepth details about it and explaining where I have went wrong - THIS IS AN IDIOTS GUIDE. Short and to the point just to help people get their heads around it initially, before they head off and do more reading around the forum.     PCD: Pitch Circle Dia
