And really....(bangs head on wall)....i had a b13 ser with stock 4x114 240 15 inch wheels. has to be the right set, think theres 2 diffrent offsets, but....mine bolted on no spacers. Now i have a nx, with 16 inch wheels. take the SPINDLE assembly from a 95-99 altima, and boom. straightforward as hell. for those of you who are lazy, use rotors off a old m30. no mods needed, although its a little thin for my taste. but it all works.
