Are those 5 on 5-1/2? - I may have just done a dumb thing - I just had carlisle tire build me a set of 6 on 6 for the old 6 lug pattern in 15x8 for the front for 270.00 so I could take the extra 15x10's and drill them for rim screws and stuff slicks on them for drag nights.. I could have just changed the rotors back to 5x5 and I would have save in a few months because then I wouldn't have to order special rotors from ECE again, I could just get the standard shelfed items at half the cost... doh!
