Z32 brake caliper help

[Nissan24zeroSX]

I got a set of z32 calipers that the bolt doesn't fit the hole in the factory knuckles on my s13.
I just need the threaded insert that goes into the caliper so I can get a bolt that fits the hole in the knuckle and bolt to the caliper.
The thread on the insert needs to be 12 x 1.25.
I need 4 of the inserts.

here's a link to an image for a better idea of what i'm talking about.

Nissan can probably get you them. I don't understand how the bolt doesn't fit. It's literally a bolt on mod. I've never heard of anyone having this issue.

Yeah are the threads just jacked up? Can you run a tap through them to try to chase them and clean them up?

My buddy told me the newer 300zx made different calipers from 1998+.
The bolt that I got with my calipers is too big to fit the two holes in the knuckle to bolt the calipers on.
My only options are to drill the holes bigger on the knuckle "don't really want to do that"
Find the right threaded insert, or get different calipers.
I'm going to Nissan later today to see if they can help me, but I'm having my doubts so I'm just curious if anyone has the inserts available.

Nissan didn't make the 300zx after 1998....

Can you post a picture of the entire caliper so we can see what you're dealing with?

The only thing nissan can do for me is sell me a whole caliper for 380 a piece.
Not doing that.

I'm not sure what you've got there, but I don't think its a Z32 caliper.
Z32 calipers have much more rounded lines for the pistons, where yours are just straight.



You can always just get calipers from autozone or advance or something too... it'll be way cheaper than the dealer.

I know the ones I have will bolt right up, but I can't do that without the right hardware.
The holes on the calipers line right up to the holes on the knuckles, only thing stopping it is the threaded insert.
Plus I got the z32 rears and they bolted right up no problem.

I've never heard of this problem with Z32 calipers. I guess your options are to try to swap out the inserts, re-tap them to the correct thread pitch, or get/make bolts that match your current inserts.
I found a thread with calipers similar to yours in it. They are saying they are skyline calipers. It mentions that they come with the bolts required.

They look like skyline calipers like smurf said. They are pretty much the same as z32 calipers but take a slightly different pad.

I was told a z32 pad will work
I just need to figure out the best way to mount them
