I am curious. Is it possible to swap the NA's four lug hub for an NC's 5 lug hub? I figure this would be better than an adapter plate if it is doable. Also I just have to say. I'm a little disappointed that Mazda went back to the four lug hub for the new ND's. At the same time. I must commend Mazda for bringing the weight back down so it is only 1lbs. heavier than the original NA.
