fitting oem staggered 124s
 

Any advice as to what size spacers I should run to clear stock suspension on the rears? I'm thinking either 12 or 15 and hoping they won't rub at the fenders. The rears are 18x9. I'm planning on leaving the suspension stock and running stock size rubber on the rear (275/35 18). This is assuming the 55 offset will rub on the inside.

Thanks!
