I have a set on my car 15-8 rear and 15-4 front, there a little heavier but not by much I had stealies way heavier. lol about the same weight as my dads centerlines dunno if they are cast or forged tho.

I'm looking into getting these maybe. I have steelies on mine (15x6 and 15x8) what size backspacing would you need? I have a 80 bu (has a 275/60 tire on rear already and doesnt rub any)
