Hey guys, I'm sitting here thinking about my plan of action for swapping over Z brakes onto my s13. I just found out that Q45 uprights, hubs, and ebrake assembly are the same as the z32TT. Now the problem with that is that the TT hub is 30 spline vs the s13 29 spine.

Now, I've read that the 30 spline axle from the TT and the Q45 have a 5 bolt star pattern on the diff connection... is that the same size and bolt pattern as the J30 axles? I ask because I'm running a 180sx diff with the 5 bolt pattern and J30 axles, so if I could straight swap the Q45 axles on there with my current diff I would be set for my z32 rears. Any info here would be much appreciated! If no one knows, I'll run to the junk yard and do some measuring and report back here.

The z32tt axles are 6 bolt so won't work. Q45 depending on the year, can be 5 bolt or 6 bolt. here is what I would do, use the axles/hubs/ knuckles you already have (unless you are planning on switching to an upright strut) and take everything apart and insert the parking brake assembly and then put back together and then use the q45 caliper and rotor.
