I was trying to search this but it wasn't working. Is the taper for the control arm mount on the knuckles the only difference? Other than that the s13/s14 knuckle look the same.

the bolt holes that go to the struts/coilovers are bigger in the s14 and the spindles on s14s are larger

Bolts are only bigger on 5 lug

You can mount them right on the s13 chassis. Its probably not optimal sulution but it works.

Yeah. Using s14 lca is nice because there something like a half inch longer. But I just need to know the differences between the two.

4 lug and 5 lug S14 spindles are the same.

They do fit but you wouldn't want to risk your car or your life on it.


To the OP.
The differences are the shock mounting holes (S13-12mm vs. S14-14mm)
The ball joint taper(S14 is bigger I believe)
The hub mount is thicker and shorter on the S14 spindles.

So everything else is pretty much the same including geometry?

I'm not sure since I've never taken any measurements of them.
Here is a side by side pic of them(S14 on the left):

s13 knuckle has smaller spindle bolt/nut sizes and uses a different ball joint.

Does anybody know about the rear? I was wondering if the upright bushings are the same for S13 and S14.

Rear is the same except for the strut mounting point.
