Ok guys

im still confused with a few things

i found a list of LCAs and what sizes etc...
Model - Length - CT Dia
RA40 - 300mm - 12mm
TA22 - 300mm - 12mm
AE86 - 300mm - 12mm
KE7x - 300mm - 12mm
XT130 - 310mm - 12mm (RT132 too?)
MX73 - 304mm -12mm
MX62 - 365mm - 12mm
GE Sigma - 330mm - 12mm
S13 - 350mm - 14mm

now it seems everyone goes with the XT130s what i want to know is if i do the same what exactly do i need to do the job, what parts do i require i know i need the XT130s but what else and has anyone one done a write up fo this?

thanks

nothing else.

the xt corona has lock stop on the lca. you need to cut these off. thats it. your stock tie rods and rack ends will have enough adjustment in them. if you have power steering as as well though, you might want some longer tie rods or rack ends.

you can grab the tie rods off the corona as well. theyre a 2 piece turnbuckle design, and have a greater range of adjustment, and are on car adjustable too.

if your tie rods you have on your car are new say, but your stock rack ends are fucked, just get ra60 rack ends. theyre a touch longer.

either set up will be long enough.

also xt/rt 13X are all the same.

would it be better to use mx62s?

slydar
8th February 2009, 07:02 PM
no. i would only use mx62 arms if you want full "oni kamu" style. its really too much to work properly. youre talking in the region of a minimum 6 degrees negative camber. maybe 5 ish with strut tops wound full positive.

if i wanted -3 camber and had strut tops + RA60 struts, what arms should i be using? i was guessing sigma but am unsure

I thought ra40 and xt130 lca were the same length

mx62 would only really be good to cut up into adjustable ones as you have more meat to play with and would likely be bit thicker and stronger than other yotas of the same style lca

Im using XT130 LCA's, KE30 Tie Rod Tubes, and RA40 Tie Rod ends on a KE70 rack. Can be adjusted to be even shorter or heaps longer then stock Tie rods.

Agreed. I have them on my RA65 and it's heaps of track. I run 14x7 0 offset with about 4-5deg neg camber so they sit under the guards.. Will be going s13.

Hen may possibly be a nut
19th February 2009, 03:20 AM
MX62 are way too long for normal use, and also their balljoint is alot bigger than AE86 so donøt suit the steering arm. Use them only for S13 conversion.

Egg, RA60 struts give about 3 deg positive camber if run on a stock AE86. Sigma arms give around 3 deg neg camber when used on a stock AE86, so going Sigma and RA60 should give roughly zero camber. But if you are doing it I'd be interested to hear what it ends up giving.

Using XT130 arms (also heard rumours RA40 are the same) I used AE86 rack ends, RA40 tie rod tubes and RA40 tie rod ends. So very similar, if not the same parts as Dan above.

I just want to point out at least a few of the measurements in the top list are wrong. When you measure the effecting length of a lower control arm, it should be from the middle of the ball joint, the the middle of the bolt hole. The pivot point of the ball joint can't be measured exactly, so you have to imagine where it may be. Move the ball joint around a bit so you can get a better idea of where the centre may be. After doing this, I think the list would look closer to this:

RA23/28, RA40, RT132/XT130 (all the same part) 300mm
KE30, KE55 etc 300mm
AE86, TE72, KE70, AE71 290mm

I still need to measure this better.

Vance
19th February 2009, 12:59 PM
what if i lowered the car like a mofo and used rca's? that would add a bit of neg wouldnt it?

Jonny Rochester
19th February 2009, 01:13 PM
what if i lowered the car like a mofo and used rca's? that would add a bit of neg wouldnt it?

It would make very little difference to camber. If you wanted negative camber, you either adjust the strut tops, or additionaly you can get longer lower control arms. (Either Sigma but I havn't looked at them, or XT130/RA40 which are +10mm I think, or have the AE86 ones lengthened which isn't hard). Or you can also get offset RCA's.

Vance
19th February 2009, 04:52 PM
my last post was in addition to my first in this thread. im guessing

ra60 struts +3, sigma lcas -4 (closer to -4 than -3 apparently), t3 negitive camber rcas -3 and play with the cambertops to get -3 overall.

Javal
20th February 2009, 11:18 PM

jonny is correct

Johnny wins.

Also, RT133 are the same as XT130 / RT132 obviously.

ST141 and RT142 are 290mm

DAN-86
21st February 2009, 02:57 PM
Just fitted Ra40 LCA to one side of me Ksev (havent done other side yet)
they are +10mm longer then stock items.

all bolted in well, RA40 LCA, RA60 tie rod tubes, RA40 Tie Ends, KE70 Ball joints, New Bushes from AJPS everywhere up front :P .

Should drive alot better when Done :D

I'd like this clarified also....
Are new rack ends or tie rods needed at all? if so what is the best solution/option?

Jonny Rochester
28th February 2009, 09:51 AM
If you use 10mm longer control arms (such as RA40), you then need to adjust your tie-rods 10mm longer. I think there is just enough thread on the rack end, but don't take my word for it, check this. A safer option is to change to RA40 tie-rods, with the seperate ball joint on the end. You will then have more adjustment, and enough thread to make it safe.

Or, if you use a steering rack spacer for extra lock (with requires shorter tie-rods) the effect may cancel out and you can use standard tie-rods and rack ends.

Hi guys,

I have powersteering in my 86,

Planning on using KE30 LCA`s as they are same as Xt130 & TT132.
If I get Longer Tierods is that all I will need? I wont need both longer tie rods and rack ends?

Cheers Keisuke

If i put sigma arms on my xt130 struts and cranked my camber tops all the way out to battle all that camber. How much camber would i be left with? or just a shit load of track?

ke30 and tt132 (xt130) are identical from the ones i've pulled from cars. measured my ke70 lca at 290mm and ke30/tt132 at 300mm. whichever way you measure theres about 10mm longer there. bolted up with a wee tweak to suspension angles.
my front suspension consists of ma45 (jdm) strut with std 10" solid disks, ae86 p/s arms, tt132 lca, ae92 shock spaced down, makita springs. i gained -1deg camber each side and also +1deg on the caster when wound all way forward which is now 3.5deg. once i get rca's in there it'll probly bring it back to vertical so then camber plates should hopefully get my -2deg.

Do i leave the sigma ball joint or do i use the corolla ones

fixeruperer
24th July 2009, 09:59 PM

use the sigma ball joint, but the taper is differant on the steering arms.take your steering arms to a machine shop to machine the right taper for the sigma b/joint
and shits safe.

dunga70
27th July 2009, 03:30 PM
With all these control arms. When you replace the bushes do you use the ones for your car or the ones for the model of car the lca is from?? Or are they all the same?? Probably a stupid question..?

bigm
27th July 2009, 08:43 PM
be safe and use the ones from the car they are originally from.

i know sigma ones need to be cut down.

bigm
29th July 2009, 03:27 PM
IF you are running sigma arms it is a must, as the stock ones do not have enough adjustment.
If you are running corona, ke55 etc(+10mm) or stock arms its not necessary as they have enough thread for a normal toe alignment.

rolla_boy70
29th July 2009, 04:44 PM

23rd August 2009, 04:55 PM
Johnny mentioned lock spacers before, but haven't heard anything since...

If I put KE30/KE55 LCA's in my AE71, with an AJPS lock spacer on the rack, everything such as castor rods and sway bar and ball joint will bolt directly up, and I wont need to get different tie rod/rack ends...correct?

If so, and then I put p/s arms on, would I then need to change tie rod/ rackend?

bigm
23rd August 2009, 10:31 PM
Stock tie rod ends will work with or without power steering arms with the above setup

hugh
23rd August 2009, 10:36 PM

i'm running te72 LCA's on xt130 struts in an st141......with about -1 camber

the te72(t18) arms are the same length as ke70/st141 etc.....but,where the ball joint is they bend up on more of an angle?! hence creating negitive camber.....Or so I've found!
Don't quote me on that!

i'm sure most of this has been covered through the thread but not in an entirely direct manner.

i will be using Power Steering arms, lock spacer and XT130 LCA's on an AE86 Strut.

heres my questions, inb4 flaming for noobness or not reading thread properly rabble rabble.

1. i know i need to cut off the lock stops but when i rebush/joint the LCA do i use Xt130 ones or AE86 ones?

2. will it be necessary to run different rack ends or tie rod tubes/ends?

3. if so do i just want the tie rod ends or tie rod ends + tubes?

4. will any of this change when i coil over the strut with Camber Tops and RCA's?

Sam-Q
11th October 2009, 08:17 AM
1: the bushes should be the same but to be sure order xt130 ones

Trial and error works! lol

refurbishing them is as easy a getting the grinder out and a black pressure pac!!

Chop off lock stoppers,clean and paint! of course you could go all out and powder coat em?
Bushes and ball joints need to be pressed in at a shop that can do so..

GJ sigma LCA's and ae86 LCA's

edit*
Q: anybody know the length of GJ sigma LCA's? or are they the same as GE sigma LCA's?

A: measured the GJ sigma LCA's and they're about 340mm-350mm. To fit these i have had to get the balljoints machined to fit the powersteering arms and have had to get ae86 bushes(60mm) replacing the 65/66mm GJ sigma bushes

hmmm, running these would probly give about 5 degree neg camber with no cambertops... and probly 3 degree negative!? as the minimum with cambertops.

will post what i end up with.

hachi_dk
7th November 2009, 08:48 PM
anybody ran GJ sigma arms before? pro's? cons? opinions?

also, anybody know, if i use johnny's extra lock tie rod ends with stock ae86 rack ends, will there be enough adjustment to get them to reach or will i have to upgrade to something? not too sure about rack ends so somebody let me know.

MX62 are way too long for normal use, and also their balljoint is alot bigger than AE86 so donøt suit the steering arm. Use them only for S13 conversion.


what if i were to use the mx62 knuckle, brakes, strut etc aswell? since the spindle may actually be at a different angle.
i am buying an rt142 and for a brake/track/camber upgrade im considering using mx83 or mx62 front end stuff (converted to coil-overs). i have a feeling that perhaps an mx62 strut/spindle on say a 300mm long LCA will lead to positive camber.

what do you think?

mad thread. i got 86 struts, ps arms,rt132 lca. bought lcas not knowing if it was right but feel a lot better now. the xt130 and rt132 were the same bodies so i took a punt. ive never heard anyone use a different model name except xt130 so thought it had to be them and them only. theres no xt130s in the wreckers but heaps of the other model. from a streeters pont of view, fuck sigma looks excessive. car looks mad yes but i dont think -5 camber is gunna benefit the car at all. tyre wear would be rediculous. probably mad on a race car though. is anyone out there running sigma on the street?

Greenmac - Plenty of people have bolted Corolla steering arms onto Sigma balljoints. Not a great fit, and I don't think I'd do it myself, but can be done and I've never heard of a snapped balljoint from it.

RA40 balljoints will fit Corolla arms. They use the same balljoints.

I ended up doing the t3 weld on kit. Now to figure out my tie rod situation, pretty sketch to go wider than 30mm.

Anyone got a known measurement for an XT14X corona? i tried to measure compared to an XT130 but i only had a ziptie to measure with. Im thinking the MX62 arms will go well on a corona somehow...

st141/rt142 are the same length as kesev ae71 sprinter... like, 300mm i think. mx62 will be ridiculously long but they are how-ever a good thing to use when doing s13 front end. i used silvia recently and they are shorter so a bit more conservative but more drilling to make it fit and less castor due to mounting points.

is that a big crack running down your caliper?

but man those weld on kits look the shiz!

ive read the hole artical but i have stock suspension just upgraded springs and the car is lowered, from what i can understand i can put xt130 lca in my ae86 and use all my standard parts that are in my ae86 (i have no power steering). i dont have camber adjusters either, and what i want to know is what camber will the xt130 lcas give my car if i fit them only???

has anyone fitted mx83 control arms? im running the GJ sigma arms at the moment and they bit too long (longer than the GE ones, being 340mm i believe). someone selling mx83 arms and they measure at 330mm. Wasnt sure if they balljoint suits ae86 steering arms along with castor rod holes and swaybar pins.

Yeah, dont bother unless you are going to a full MX83 front end. I have a full MX83 front end on my Supra, and its quite nice, but the balljoint is unique to the MX83 and so you need to use the matching steering arms, and then the matching struts as they are odd spacing too... etc.

So if i wanted to cut my LCAs and make them longer, about 10mm would give me an extra degree or so? and also, also would like adjustable LCA's so if any1 has a build/howto thread on what you need to do that would be awesome
sorry if its been in this thread before, i just quickly read over it.

techno toy tuning make a kit.

but my gut tells me that if you need to ask for a tutorial on how to do it, you probably shouldnt do it. LCA's are kind of important on a car...

i know how to do it i guess, just wondering on the would one rose joint be good enough what strengthening needs to be done... i can do the work.

hmm well in that case, I would look on the T3 website and pretty much copy their design if you dont want to buy the kit.

I was looking at doing the same thing, but concluded that for the amount of effort and time it will take, it will end up cheaper to buy the T3 kit.

Maybe even look at making a whole new arm and replacing the ball joint with another rose joint? Anyone have opinions on this?

Thought I would add that MX32 LCA's come in at 335mm.

So what steering arm combo would be needed to pull 45mm positive adjustment? ANyone got an idea?

old thread dig up but help a brother out.

the quote is reffering to sigma lca's. what exactly needs machining? slightly confused after reading th entire thread at 10.30pm after multiple beers...

thought i'd add.. people asking about mx83/gx8#/jzx8# lca's .. they have a larger bolt through the pivot bush. (other end to the ball joint).

and could the OP please update the first post so the list is corrected?!!

re ball joints.
A6 celica/carina *4cyl* have same ball joint thread and taper as ke3/e7/tt132/ae86.
ma6/ga6 celica-supra 6cyl have a larger taper but with same 14mm thread. mx8#/jzx8# etc have a larger taper ball joint than the ma61.

compared these moons ago.
