2 OR 4LINK coil suspension ideas for ke20?????

[mid9-5's]

As it says anyone with a good rear suspension setup something along the lines maybe of an ae86 setup,
i want to remove the rear leafs and run a coil setup without cutting anything or having to make a rear cage, i figured it shouldn't be to hard just wondering if anyone has done one i could have a look at before i start,, i will be using a cut down R31 diff,
cheers

i think you will need to cut something.
plus need to strengthen the shock towers.

stock, there is no space fro the top arms, so you will need to box them up, like done for old rally escorts etc.

if for the road, have a good talk with engineer first, as it is considered a major mod (at least in NSW)

talk to me and nick some time linds, were making a 2link setup with a wattslink(panard rod) arm in nicks 1200 wagon, using beefed up front mounts for link mounts and almost motor bike sized coil overs with reinforced bracing.

much like and 80 series cruiser front arm setup.

or check out callums (WYD BDY) ke70 ute, for mount ideas.

ive never seen or heard of only one doin this yet, unless its a drag setup.

OH and this is dan if u didnt work that out by now.

[oldcorollas]

like this eh?

[mid9-5's]

yeaa i know its your dan haha,, i was hoping to use the front mounts where the springs are run 2 arms back from there and then make up a braced section run a coilover shock and then yea panard for the rearside so much the same idea, ive got the nxt 3weeks straight pritty much to get sorted on the rolla and get it in the shed as i'll have the patrol by then hopefully,,

oldcorolla i would like to keep it close to as stock without cutting 2much espcially like your pic haha wouldn't mind keepin the rear seat in there lol if u have some photos of some good setups tho would be good to see them??? cheers
once its up on hoist and im looking at it i'll come up with something quickly haha

i have not seen a 2 link on a KE20 before.

so the two arms will be rigid to the diff housing?
how will the car roll?

in terms of "good" setups.. i am not sure there is a good 2 link?

what do you want to use the car for? just rolling around? or trying to put power down?

[Hurricane]

the setup me and my brother are lookin into will consist of 2 main arms, there in a Y shape or a straight bar, it will have one bush at the chassis end and two at the diff end (ether two and the end of the arm, or one at each end of the Y arm) then using a watts link or a normal panard to stop the diff from rolling left or right.

lots of stock 4wd's use this setup, so i cant see why it can't be used on a car.

now i think of it that a 3 link setup right?

here is a shitty pic of the diff end of the arm on my 60 series cruiser with 80 series diff(showing the two bush mounts)

80 series arm ends

the idea for it is to get rid of the leafs, becasue of axle tramp and side to side shift of the diff and to see how it would work out!

4 or 5 link setup would be the way to go about it, but its not much of an option with out cutting the floor apart.

[oldcorollas]

panhard rod/watts link can be used with leaf springs as well to laterally locate the diff.

axle tramp is usually due to shocks not doing their job.
are you getting (or anticipating) leaf windup? that can be countered by stiffening the front half of the pack
(kinda like integrated slapper bars)

the question is.. will this 2/3 link control tramp?

[Hurricane]

yes ur right, we did have a watts link setup that we were goin to make.
my bro wanted to run coil overs also.

we have tryed softer and stiffer spring packs and shocks, there did help but never got rid of it. it was more the leaf pack twisting.

i to was never sure how well the 2/3link will control axle trap, ive not finish my cruiser yet so i can test it there,
we could make a cheap first setup and see what effect it has on tramp, i see that it might try and lift or sqwot the rear end on take off?

I was thinking of using a 2 link setup to go along WITH the leaves. Why do the arms need to boxed so high?

I mainly trying to reduce tramp aswell without going tramp rods.

[oldcorollas]

squat/lift will be determined by the angle of the lower arms, and where they point in relation to CG etc

the arms are boxed high so they are more parallel, and longer.
making the arms are apart vertically on the diff make it easier to control diff rotation, and reduces the effect of bush compliance on rotation?

by makign the front half of leaf pack stiff or rigid, you effectively are making a 2link, and roll compliance would come from the rubber between leaf pack and diff.

tramp ight also be coming from that rubber too.. cos the rubber aroudn the leaf pack, that gets clamped to the diff spring platform thingies, is a fair bit softer than the leaves, and the distances involved are small, so there is a large torque loading on them, ie large forces...

what i mean is, the diff and the clamps for the packs might be wobblign around on the leaves themselves, as opposed to the leaves actually winding up?

a top link would help there

[Hurricane]

what im think(half guessing) is that the more the 2link arms are angled away from parallel, the move squat/lif it would have?

on all are leaf setuo we have removed the rubber the leafs sit on between the diff mounts.
my brother also played with tramp rods but is not happy enough.

in my ke20 ive got a stiff leaf pack with a load leaf and it does rather well with tramp so far.
i also made the diff mount platform longer to hold more of the leaf pack.

i will be good to see how the 2/3link setup will go though, i think it will be better when we start to lay down a lot more power. and it will be easy to setup spring rates with coilover springs and shock.

[oldcorollas]

chances are, it will squat., cos the arms won't point up enough to push through CoG.

is this tramp doing burnouts? or just trying to put power down normally?

yah, easier to know what your actual spring rate is, and far less stiction

[Hurricane]

in my bro's 1200 it was both, but more the launch/takeoffs, he doent do much in the way of burn outs.

using semi slicks it was really bad on hard take off.

ive not ran semislicks on mine yet, but so far with the stiffer leaf packs its been or with both.

also runnig coils makes it easyer to change the ride high with out changeing the spring rate, or removing springs all the time.

also with my bro's 1200 its a wagon, so u really have to cut up the floor alot to run the toparms for a 4/5link setup, so if we can get the 2/3link setup to do what we want to, it will be a win.

hmm.. De-dion rear end?
do it like this and you might be able to use the stock leaf mounts.... to a point...
