no my wheels bolted right on. but i do have a set of Toyota wheels that would need wheel spacers. but they would need spacers even with old brakes. these are 87 fj60 rotors. i freaked when i bought them and they heard you had to use fj40 rotors. but as it turns out the 81 and newer rotors fj40/ fj60 are the same. i may go to spacers when i do the 90's truck rear axle to keep them the same. thanks for all the help.
