Im Running 20" axis shines that are +20 offset in the rear. I'm thinking about runnin either 15mm spacer or 20mm spacer to poke em out a bit but im not sure if either will rub. I'm running 275s in the rear and may drop it in the future (maybe). The fenders are going to be rolled regardless, but I'm tryna figure out which of the 2 will look better and give me less headache as far as rubbing and bumps are concerned. Which would any suggest?

 

15mm you might be ok....you will rub with a 20mm for sure if you plan on lowering the car.

 

20mm you will need a smaller tire size to clear. Camber helps too.
