i need to find a machine shop capable of creating cusom rear lower mounts for a set of coilovers, i have s13 kei office coiovers and i need a rear lower mount for an r32 GTR/ z32 to suit my z32 rear suspeion.
what exactly do you want these rear lower mounts to look like? material?
make a sketch
sure thing, the stock ones are aluminum and that would be great, but pretty much every other companies are made of steel and that’s prefectly fine by me, if the cost is almost the same then aluminum by all means…
here my sketch:
that is going to be expensive i think…
i imagine that you would tap a solid piece of metal, you’d have to get a X" thick rod and tap it then weld the bracket on to the end.
i have a shop that does my multi-link that would do it for you but i have no clue how much it would cost.
Yo Ted. Splparts.com sells the Z32 brackets for their KTS coilovers for $95usd a set. I don’t know if they will fit the Kei Office coils tho.
well the tein ones take a steel pipe of some diameter, then thread the inside, a very large tap would be required, then the fork is just a bent metal palte welded to the bottom… i expect these to cost some significant coin, but gettign the ones from kei office is proving equally difficult… so yeah next time your by inquire on my behalf
Yeah, that is going to be pricey.
It would be easier if you could use the existing threaded piece and affix what you need to the bottom of it. It is adjustable, so it could be a little longer anyways.
I have a machininst near here that does excellent work! He is currently redrilling a set of rims for me that were bastardized by another machinist. Gunna cost a few bucks tho… Not saying he is a ripoff, he has great prices but is top notch, I just need alot of tedious work done on these things.
If you are ever in the area, let me know and I can hook you up with him.

yeah i know kts sells them, i had thought og buying kts coils before, so far i’ve tested teins and the thread pitch is all wrong, d2’s are far to small, i’ve yet to try jic as i don’t know anyone with them… i hvae no idea how i’d be able to check if kts fit without trying them by hand,
thanks theo next time i’m in the area i’ll have to give you a call, i don’t mind using the exisiting at all but was concerned about the strength of welding an aluminum fork to the botom, i’m no welder or metalurgical engneer so i dunno if i should be terribly worried about weakeness anyways, if i do that anyone know a palce that anodizes things lol
i just dunno if they cn do that or not
So you want your lower foot of the shock to go from whats known as an ‘eye’ mount to a ‘clevis’ mount
Most coilover’s I’ve toyed with are all metric threaded, all their bodies are threaded with the same OAD (Over-All-Diameter) and pitch (the distance from one crest of the thread to the next crest of the thread).
So just measure the what size thread you got now on your shock body, then go call around places like JIC, OMNI, TEIN, KW, Tokico and ask them what size thread/pitch they use on their shock bodies, if its the same then just order one up a clevis mount foot from them…easy
If you insist on custom made then I would take a piece of round stainless, find someone with a lathe and turn it to the correct outside diameter and inside diameter, then get them to cut an internal thread on the lathe (the cost for a tap that size would scare you and it’d be custom made as well).
THEN you take a stainless disc that’s say 25mm thick threaded on the outside with the same thread pitch as the tube you just made above. Now drill and tap a hole in the middle of it a certin size.
Thrad the disc into the tube you made above and have someone tig weld it solid so theres NO WAY IN HELL it’ll come out. Machine the bottom flat after tig welding…
Why stainless so it will never rust. Why thread the center you ask, so you can have different size clevis made (stainless as well of course) with different offsets to compensate for different suspension geometry and setups…which is an entirely different discussion…
2 options…
#1 ditch the Z32 Spindle and swap the Ebrake setup onto a S13 Spindle
#2 Buy Brackets to fit Z32 rear spindle, available separately for $95/set @ http://www.splparts.com/Parts/S13/Suspension/Coilovers/ IF the thread size/pitch is the same etc… as the Coilovers you have now
yes i’m quite aware of that… do you enjoy repeating things or somthing? :roll: i put alot of effort into using the z spindle thers more to it than just boltign it on lol… i’d rather not tear it all aprart and go back to stupid steel s13 ones… i don’t need help with what to do about my problem, just who to do it… and possibly how.
matt had some nice info, i knew tapping it wasn’t the way to go but it seemed easier to just say tap lol, thanks man,
so exactly where / how do i want to be measuring if i’m gonna be callign up a few companies…
caliper to measure the diameter of the shock body (threaded portion), thread gage to measure the pitch
#1… I didnt read the thread and just your post
#2… I noticed after I posted that someone else had already posted in regards to the lower brackets from KTS etc… but was to lazy to edit my post
#3 what effort to use a Z spindle ? it is pretty much as simple as bolting it on minus the fact you must use the Z strut
#4… what about cutting off each lower perch/mount from the brackets and then welding the Z bracket to the kei-office bracket (may be easier then having a whole bracket made or what not)
ok then that’s fair man,
-
you need to cut the dust gards off the axle, and purchase these aluminum hat things from nissan to go over the ball joint before you can fit the aluminum upright… and it’s not that hard once u know those things but if u don’t it can be annoying… i did this long before people had written that u need to do thsoe things, also my car was being a pertcular pain in the ass, so i don’t want all the time it cost me wasted
-
that was also mentioned, and the kei office bracket is aluminum, where the stock z strut is steel. what i had asked is if an aluminum fork is made and welded to the bottom is that strong enoguh for a suspension mount?, as i said i’m no welder
some dimensions would be cool, Like the “bolt hole” what dia. ? Thread ? there are too many threads to name… if you can measure it I might be able to help you out.
get a vernier and start measuring.
haha you asked for a rough skecth haha, at least you know what i’m looking for now… i’ll start the measuring process now and have a new cketch up in a few
so what you have there is a threaded rod and a threaded coller, problem is that thread has to be machined on a laith, not just with a tap, theres your time = money.
yeah how much money tho lol
