The best and most efficient way is:
B15 front hubs and spindles and brakes (get hubs redrilled to 5x114.3)
90-94 Maxima rear hubs and rotors and torque member
I make the spacers and sleeves that you will need for the rear setup....there is no way around this because the B13 and B14 have tiny ass shaft's that the rear hub bolts onto and you'll need the sleeve to accomodate this and the spacers to correct the offset of these hubs so that everything is back in alignment.
I also redrill hubs so you can hit me up for that service if you like.
This are some pics of a B15 front hub I am doing for another fourm member, these are being redrilled out to 5x114.3 for use on a B13.
