4x108 - 5x130?

Well that above shows you exactly how they would it sit in the arch ^^^

But as far as offset goes (et), basically if you have a et 23 wheel and put a 20mm spacer on it becomes et 3. Like wise a cyclone at et18 with a 10mm spacer will become et 8. Its a measure of how offset the face of the wheel is from dead centre. A lower or negative offset will sot out further than a higher offset
