Dude, your question is exactly the purpose of this discussion. We don't have the answer you are asking for. That's why i want all the measurments i asked for in the first post.

heres what i have...


S10 200sx front caliper bolt pattern is 3 inches center to center.



4 cylinder s12 200sx is 3.5 inches, these are off a car that had a CA18ET in it and are identical to the ones from thisismatt other than those ones were shortened and coil overed.



Its confirmed that s10 and s12 use the same spindle,  BUT THE S10 takes a larger seal! the s10 is about an inch longer in the seal area than the s12 spindle. when I did this swap the stock struts made the tires poke, where the s12 struts tucked in.


S10 200sx seal size



4 cylinder S12 Seal ID


4 cylinder S12 seal OD


S10 seal inner diameter



S10 and S12 share the same pin inclination angle



The s12 strut puts the strut pin a lot closer to the ball joint centerline



S10 disc flange height



S12 Disc flange height...


S10 wheel flange height


S12 4 cyl hub wheel flange height



I hope all this is helpful

It should also be noted that the S10 hub is quite a bit heavier than the S12 hub.

I would like to see how these compare to other hubs. (280zx, 300zx, 510, etc.)


What I want to do is mock up the S12 4 cylinder strut with the S10 hub, S13 257mm disc bolted to the rear and a Toyota s12+8 caliper bolted right to the strut.

using the S10 hubs it will move the disc very close to the strut and with my offset wheels the disc is probably going to be outside the rim with not much caliper in the rim. all the brakes in a 13 inch wheel.

kinda like this setup

If you measure in metric you'll get more round numbers, and I find it easier to measure C-C by measuring edge to edge...same number, easier to read.

Another thing to note is that steering knuckles have the ball joint stud hole in different positions, side to side with respect to the strut. This alters camber/scrub radius/track width/etc if you change from one knuckle to another. For example, 510 vs 280zx:
