You generally need something between et18 and et25 in an 8 inch width.
Why is this?
Stock 18's are 18x8.5 et29 and 18x9.5 et23. So going by this the et35 on 18x8 should work, however there would be a decent amount of gap between the fender and the wheel.
9.5s use et23 and 8s with et35, thats a 12mm difference in the offsets and the wheel width is 1.5 inches shorter so 0.75 inches shorter on the inside. 12 mm is about 0.48 inches so the inside clearance should be fine. The front should be ok as well.
Is there an issue with brake clearance?
