Front suspension




^ A-1 Tie Rod Ends, for using the S13 knuckle with S12 inner tie rod ends.


My coilover collars are stuck. DAMN RUSTED USED ITAMS!!!111 It should be broken loose tomorrow and hopefully I'll have pictures of it rolling.
[mod edit: use anti-seize]




REAR suspension




I'll have more up later.

[mod_mastaz]

Yep, I still need to roll this car out of the garage and get some S14 rims. Those Z32 ones are toooooo wide in the front. I like how the back sits tho haha. I still need an alignment and other things.

[mod_mastaz]

I think I'm gonna stick with the Z rims. I just gotta go positive camber near the spindle and a 10mm spacer to clear it. The rears look VERY nice. A little too low for my liking but it's not bad. MORE PIX TOMORROW! And I need to get hardware to mount the stock front sway bar.

[EternalSwap]

Positive Camber? You mean negative, right?
Looks awesome man. The Z32 wheels look so beffy under the S12 haha

Good to se you got it setup.

[mod_mastaz]

ATE SUPER BLUE!

RAWR I just need an alignment, everything is sooooooo off haha.

[mod_mastaz]

I'll post a list here and I'll do an info thread after this one.

Front suspension
-S13 front control arms(with ES bushing)
-S13 spindles
-S13 tension rods(Stock with ES bushings)
-S14 Tension rod bracket(had to oval out one of the holes)
-S12 stock swaybar(need washers and longer bolt to mount it)
-A1 racing tie rod ends
-Tein HA coilovers
-Ichiba 5-lug conversion hubs
-Q45 calipers/rotors(rebuilt)
-ATE Super blue
-HAwks HPS pads
-Z31 SS lines(all bolt up)

REAR Suspension
-Z31 87-89 vented rear control arms(stock axles bolt up)
-Z31 87-89 vented rear rotors/calipers(rebuilt)
-Hawks HPS for Z31
-Mustang AGX shocks(with washers to keep the mustang agx from moving left/right)
-5x8in length 350in/lb springs(no need to cut the control arms for me!)

Rims
Z32 NA with a 10mm spacer in the front. I just gotta get some stretched tires so I can go 5mm all around(I double-stacked 5MM spacers)

All I need left are Rear subframe/diff mounts, Poly spring seats, Z31 poly bushing set, R200 diff and 5speed swap. Eventually I'll get a CA18DET and rebuilt B trans(since I have a MK1, I'm trying to keep it simple as possible). So far, EVERYTHING bolted up, although the S14 bracket needed some modding.

Thanks for the comment guys. I've just been really focused on the S12, haven't been reading any comments or anything. At first I wanted to dump these Z rims but it just looks so nice now. I still need to source more parts before I get an alignment. I wanna make sure my suspension is done and I don't have to mess with it for a long while.

[mod_mastaz]

Ride height! LOW!! except on the front haha.


Tucking rear with vented brakes!

PROOF!


Front not so low =( but as soon as I get stretched tires and take off a 5mm spacer, it'll match the rear!

[worr20]

where did you get the 5x8 inch spring?

[mod_mastaz]

I got it at Pitstopusa.com. I kind of wish I got some 5x9.5" springs instead, cuz my car is WAYYYYY too low. At the time I couldn't find the 5x9.5" spring with the rate I wanted, but it's too late to exchange. All you need to do is find a store that sells performance springs or just find a spring manufacturer. Just look for retailers that stock AFCO or Blue Coil springs. I'm gonna keep trying to find other manufacturers.

Edit: Hypercoil also makes 5" OD springs. These 3 manufacturers have varying spring rates also. anywhere from 300-1500 in/lb springs. Certain lengths only come in certain rates.

[asparagus]

I just got my 900lb 5x8 today and I'm pretty stoked. Hows your rear camber? And did you use stock rubber pads for the perches? I'm thinking about just squeezing in some heater hose at the ends of the springs

[mod_mastaz]

Damn, that'd be pretty stiff for street driving. My front is 6kg/mm, which is 336in/lbs and my rears are 350 in/lb. I hope these aren't too stiff for street driving and too soft for spirited driving. Let me know how that setup goes. Are any of you guys running the prothane spring seats with these springs? I'm thinking of getting those, but for the price, I'd rather just get a new set of springs and reuse my old rubber one or maybe using a 5" spring perch. I was thinking of welding it to my control arm so I can adjust height/corner weight it, but I might stick to getting springs in the length I want.

My rears are noticeably BAD. Somewhere around -3 to -4 degrees? I am using the stock rubber, well at least what's left of it. I still gotta put in the MMR subframe/diff bushing they sent me.

[worr20]

woo I did mine!!! PLENTY CAMBA!!!  http://s80.photobucket.com/albums/j189/90mr2t/?start=100

[GriffinW]

Awesome Info man. Where did you find your vented lower control arms from the Z31? Im guessing a junkyard but sometimes people find them elsewhere. I cant find just two front s13 coilovers ANYWHERE, did you get yours from a forum?

Also im thinking about going with a 500-600lb spring in the rear, any one know the stiffness of that range?

[asparagus]

You mean the wider rear lower control arms? They come off of any late model z31. As for coilovers, it's damn hard to find just the front pair. It's usually all or nothing. And what do you mean by "any one know the stiffness of that range?", 500-600lb is..500-600 lbs. Please be more specific, you could also do a lbs/in. to kg/mm conversion on google so you can compare those springs to any japanese/euro spring rates

[mod_mastaz]

I got my front setup from Nicoclub. My rears were from Z31performance forums. The vented arms are from the 87-89 Z31s.

Oh and new update, I just put in my S13 steering rack bushings on the driver side. The passenger side is too thin and it would make the rack uneven. Anyway, you'll need the S13 driver side steering rack bracket(its the egg shape) and the S13 ES steering rack bushings. It's going to be a tight fit and there will be a small gap when the bushing comes around, but with the S13 bracket, it'll work just perfect and add tension to the bushing. Cheap solution for 10 dollars. =) As for the passenger side, my stock one was still good, but OEM new or delrin would be nice.

[asparagus]

The thing about the stock driver side is that it's already metal, the passenger side however is soft rubber. If anything the passenger side is the one that needs to get upgraded

[mod_mastaz]

That's true, but my stock driver side was crumbling apart when I replaced it. My steering feels much better now with less free play, although I didn't get to drive it due to it needing an alignment. My passenger side probably won't get replaced because I'm probably going to get a new rack in a few years anyway and it's most likely going to be the S13 one. Or I could just make aluminum S12 mounts since I planned that from the beginning, but that's probably going to be much later in my build.

[GriffinW]

what I meant by stiffnes was would it be a horrible daily driver because the rear end is so stiff.

I have a maxima on tein s-techs and they are bouncy as hell. I definetly want something more stiff for my s12

[mod_mastaz]

Ok, so I got my MMR subframe/diff bushings in. My stock ones were fine, but I decided to do it anyway. I should have filled it, oh well. I got the subframe out without dropping everything else.  Now here are the pix






I got my MMR bushings after I sent the incorrect ones back. I'm planning on their passenger side rack bushings next. If that goes bad, I'm done with them haha. For those that want to save money/not deal with MMR, fill the mounts with windo-weld or poly roofing that Asparagus used, and grind the lip off the top to move the subframe closer to the chassis. Another solution would be to get the prothane Z31 bushings and shave it, like Asparagus did. If I didn't get these diff/subframe bushings, I would have filled them.

Here's where to grind, I just figured it out after I got my bushings out hah, but best of luck to those wanting to save money.


It's that little ridge at the top of the bushing, where metal part is.

[asparagus]

Looks great man! I must admit the material used by MMR (which is delrin) is really desirable when you want stiffness, good shit :thumbsup
