My friend has a G37 Sedan X and bought wheels 18x9.5 +35 offset and can’t seem to clear brake calipers. We tried 5mm & 10mm spacers but stills rubs. Tires are 255/35/18. Has anyone else run this size and what did you do ?

 

Difficult to help,tire size doesn't really matter. All wheel types are made differently even the width of the will change the face from concave to convex.might have to return them or take a loss

Only advice I can give is depends on much they hit the caliper is too shave it down a bit to clear.Depending on how much clearance you need
