That has been quite helpful, cheers mate, i found this:
'''What are the bolt pattern, centerbore and offsets for wheels?
The
bolt pattern is 4x100mm.
The
centerbore is 56.1mm.
The
offset (
ET) can range from 35mm to 52mm depending on the wheel size, as detailed in the FAQs on factory and aftermarket wheel availability.'''
I take it the bolt pattern figure refers to the number of holes for bolts to go into and the diameter of them therefore the wheels i get need to be the same bolt pattern as that above??
Is the centrebore the round metal bit in the middle of the hub then? Should the wheels give a measurement in regards to this??
I have found out the offset is ET42 and the wheels i have on at the minute are ET45 so i dont think that would cause to many problems
