I recently acquired two sets of lowering spindles. One of them is for use with the 1" rotor and the other for the 1.25" rotors. For performance/warping reasons I would elect to go with the 1.25" rotors if they were compatible with the 1" calipers that are factory on my '86 C10. Has anyone run into this? I have calipers and rotors that came with the 1.25" spindles, but I'm hoping I can just slap the spindles, and rotors on and not have to mess with the calipers. Possible?? Thanks...
