SBMM Pick up question

Hello all, I have a Sterling Axis AX30-D and want to change the pick ups from whatevers in them now to a liquifire on the neck and a crunch lab on the bridge. the website asks if it standard or f-spaced. which spacing do we use? thank you. currently have added locking M-6 Tuners, Tele style knobs and more mods to come.
