because billet specialties only made this one set for these cars, trust me i have looked. So yeah between the width,size,brand,bolt pattern, and cut of the rim, they are a one of a kind. Since this one is the only one like it, and there are no others, that would make it a on of a kind. And it will also fit about any wide body kit, such as mariah racing, mazda motorsports, mazdatrix (mark 4, bla bla), Shoot those with any flares can use these rims to make it look better and fill it out. So its not for only one car (and i figures that would go without saying) it was just made for the width of the widebody kit from mariah....
SO THIS IS STILL A STEAL! And the weight is nothing, they are light as hell, for any serious buyer i will get the exact weight
