longer control arm options???
|

Can anyone recommend some options for longer lower control arms to use in my ke55?
In searching the site, sigma arms keep coming up - can someone provide some more details on this please?
I want to know what model to use, if any changes have to be made, what ball joints to use etc.
Thankyou kindly.

RA40 arms are the longest arms toyota makes untill u get psyco with cressida arms or similar
Here is some sizes in comparison to AE86 arms (approx)
RA40 +10mm
Cressida +60mm
Old sigma one piece arms +30mm
Sigma 2 piece arms +60mm
For longer arms you might need longer steering tubes. I use RA40 tubes with ke55 ball joints.
+10mm equates to 1-2 deg neg camber (at a guess)
for RA60 struts use +30mm arms for 3deg neg camber or else u will have positive camber
Sigma arms are a little fat in the rubber bush which will need a little shaving with angle grinder to fit crossmember. Also one of the caster rod holes might need a file.

I will have to double check but I think you will find RA40 arms are the same length as KE55 arms. I have a set of each in the shed so when I get a chance i will get out the tape measure.

I'm using old Sigma arms, they are about 30mm longer than KE55 ones. I didn't think the 2-piece Sigma arms were any longer than the 1 piece ones, but I could be wrong. With the 1-piece arms you need to shave the bushes a little, and get a crush tube made to make the holes the correct size. Apart from that, it's a bolt on.
For ball joints just use the original Sigma ones, the taper is the same.

Thanks, you guys are legends.
Can you explain a little more about what modifications must be done to the sigma arms (crush tube??), assuming that these are my best option??
Cheers

i can help you with this, as I have just done mine on my ae86.
The things you need to replace are you lower control arms and the tie rods.
The lower control arms can be found on a Sigma GH model (old old model) with the one peice arm, press in ball joint.
The tie rods can be found in RA40 celica's, but i found that they were an absolute bastard to remove, so i went around the wreckers and mixed matched rods (ones that were removable) and found that alot of toyota's use the same tube. I got mine eventually off an old corona (can't remember model) and an RA40.
With these parts alone, you can basically bolt everything up to your KE55, but i got picky and bought brand new ball joints/bushes/crush tubes/tie rod ends/steering boots.
It was all bolt in for me, didn't even have to re-drill the castor holes (a couple of jacks come in handy here). The bushes for the crossmember you can just belt sand about 2mm off each side, and the crush tubes must be the same width as the crossmember attachment (takes 20 sec to cut with hacksaw)
with alot of grease and alignment, you'll notice an improved handling, and turn in.

Hi all, thought i'd ask this question here as its in relation to control arm lengths...
I am actually after something shorter. The AE86 ones are 300mm I think. I need something around 280mm. Anyone know if there is a Toyota with shorter control arms than the AE86? The RA28 is also 300mm so thats no good. Not sure about the TA22?
Cheers

Yeah could easily be cut and re-welded to make them shorter.
Just thought there might be a bolt in option.
It's not actually for me either, so i'm not sure about engineering requirements but they can find out that info  not my problem haha.

ae86slaver: Why did you have to get new tie rods? Mine bolted straight in.
AFAIK cutting/welding control arms is not legal, hence getting a "bolt in" alternative

I guess the AE86 tie rods are a lil different to other models with only one side of the tube being adjustable. Now the new ones look awesome with both sides being adjustable with new parts here and there

Longer arms were a great trick on TA22 Celicas. As well as gaining neg camber, you also reduced Ackerman angles (induced tyre scrub on turn for safety reasons) which improves cornering speeds. Can be a spooky on the road until you get used to it...

haha, my car turns a bit funny now, the steering is non-linear which makes driving rather interesting

try XT130 arms for a little longer than AE86, I think the Ke55 are shorter but may have the wrong bolt point for the sway bar

mad conversion!
not only do you get around 3 degrees neg camber, but it allows you to wind in HEAPS of + castor too on the stock castor rods!
although my tyres are rubbing the edge of the guard pretty bad, im going to have to flare them, no worries 
the reason for using the ra40 tie rods, is by putting the longer control arms in your making the length from inner and outer tie rod ends greater, and if you use the ae86 tie rod's they'll only be hanging on by about 1 or 2 threads, you NEED longer tie rods!
and heres a pic of the camber, i didnt take a pic of the control arms, they look exactly like the ae86 ones, just longer.
note: adjustable strut tops is a much easier conversion, this is not a bolt in swop
