Installing rear swaybar
|

Hello, wanted to ask a quick question in regards to fitting my rear swaybar.
Its a shelby sway bar that attaches to the lower trailing arms. There are 2x d-style bushes for each arm.
With this design, you can move the sway bar around quite a bit as the D bushes can slide up and down the trailing arms. Is there any set place to put it? Like should it be in-line with the rear of the diff. Or more forward? Also I'm assuming that you should have the mounts as far apart as possible or close together?
Thanks
Joel

Here is some pics of the components. Might make my above question easier to understand!

that looks alot different to the one i had on my ta22 - but the principal seems the same - it looks like it will have some movemebr - but oncce the bar is strapped onto the panhard rods - there shouldnt be much at all ..
The one i had was the hangdown type - it bolted around the diff -and onto the front panhard bar mounts ..
Made So much of a difference to the rear end balance - it was amazing !
Im so lookig forward to getting a decent rear bar in the gt4

Yeah a lot ive seen bolt to the diff or chassie but this one just attaches to the trailing arms. Hopefully it'll be effective.
Cheers

Hey Joel,
I am in the same situation as you, ive got a selby rear bar that attaches itself to the trailing arms with the d bushes, but mine came cheaper because was missing the second set of d mount pairs.. Im making them up at work placement tho so its all good, but then ive got to mount it.
Im not sure about how far apart to mount them either, but there are signs of wear on the bar i got in two distinct sorta spots so im going to have to guess on where to attach it from them..
Probably about 15-20mm gap in between, mabye someone more knowledgable could say for sure??
I saw your other post, doesnt that just suck when you buy fresh parts/bushes and they dont fit in properly, that was the same story with my front Noltec swaybar mount link bushes.. The new bushings were way too thick compared to the old four off each bolt! the new four Noltec ones didnt even fit on the bolt with those metal tubes! Havent even finished that proplem yet, just gona cut the bushes down thinner tho.. 
In regards to your problem, i guess you may have to just find a new bolt that does fit, but be wary not to alter vital suspension geometry when changing stuff.. (im no genius tho, this is just what ive heard)
When ive had the chance to make up these D mounts and get new bushes too, i'll give you an update ! Im a bit wary on doing the new bushings all round in the rear now ..  (more headf*cks..)
Hope it goes well,

G'day Joel, thats a pretty looking anti-roll bar ya got there.
I have onlt ever used a chassis mounted bar bafore, so I may be way off here, but from what I can see from your photo, It wouldn't make any difference where you bolted them up.
My reasoning for this is as follows.
This set up rely's upon the relative angle of the lower control arms to generate the twist in the bar. This means that where ever you bolt the thing on, you will be getting the same amount of twist because the lower control arms are moving the same amount.
Where this differs from the chassis mounted type is that by changing the arm length, or distance from chassis pick up to transverse part of the bar, you change the moment acting on the bar. Ie shorter arm = stiffer bar.
My advice is get the mounts as far apart as you can securely get them. This will lower the loads on the bushes and reduce wear. Have the forward one with say 5-10mm of the bar extending past the front of the mount and the back of the rear mount next to the start of the bend. That way, everything is sitting easily and not preloading the bushes and the forward mount has enough safety so it won't come loose.

Hi Joel
That one is the same as the one i just pulled of my 23, make it so the bar is just furward enough so you can get a trollie jack under the centre of the diff housing as for the d clamps as far as you can get them apart leaving about 20-30mm at the end of the swaw bar.

Hi all, well finished putting the swaybar on tonight
Here is a pic :
I had to mount it so the bar sits infront of the diff, do you think this is ok? if I tried to mount it just behind the diff it ran into the bottom of the trailing arm mounts off the diff.
Also, if you look in the pic you can see the mounts are not quite vertical up and down, but are twisted in towards the car. I couldn't seem to do anything about this, the bar isn't wide enough to allow them to sit flat. What do you all think?
Many thanks,
Joel

This was the same with the rear bar i bought, it is a selby too i think.. It is just slightly too narrow so the arms sit just inside the trailing arms.. and thus the d-mounts are slightly angled.. i think this is okay.
As far as forward or backward positioning, im not sure.. i have these two d mounts with hoops to mount the bar to the diff/axle housing also.. Did you get any of these such mounts at all with your bar/kit? I guess when i put them on mine it will restrict movement of the bar even more..
Peace

Looks great Joel. Should make a big improvement. Give it a hard time and tell us how it goes. You may find that your car has more of an under-steer tendanacy on a steady corner, but I you should have plenty of power to balance that out 
Fore aft shouldn't make any difference.
I am sure you can appreciate that if the mounts were sitting sideways, the bar would be trying to twist them around the trailing arms, but that angle doesn't look too bad, I wouldn't be worried about it, just make sure the bar doesn't move to either side.

BlackRA28 - didn't realise there was mounts to go onto the diff!?
Brought it secondhand so makes it a bit hard to know what should/shouldn't be included.
What are these extra brackets like that go to the diff? Might have to try and hunt down a set.
Anthony - will let you know how it goes when I take it for a spin tomorrow night.
Cheers
Joel

Went for a run up the Old Pac tonight and all I can say is WOW!
It has made the biggest difference. Before the Celica was always a challenge to get around corners quickly, now its easy.
Anthony you were right, understeers a bit now but not too bad.
One of the best suspension upgrades i've done so far.
Cheers

joel, that swaybar isnt on backwards is it?
most ones that i have seen have the "free" ends near the diff, and the "middle" bit nearer the front of the car.
(EDIT: doing it this way will reduce unsprung weight by a tiny amount too, and if oyu can mount it this way, the "twisting" part of the sway bar should be in line with the chassis mounted pivot point of the lower control arms)
would it fit this way??
if it fits, and it works, then i suppose thats all good,
i suppose it would work either way, but it looks a bit funny to me.

Well done. The sway bar is fitted correctly - either that or the manufactor's instructions that I have are wrong!

Great to hear Joel.
I love it when you fiddle with something on your car and can feel the difference.
Speaking of the Old Pacific Highway, did you hear that the East Coast Classic will be running a stage on the highway between Cowan and Brookland. It is on this Wednesday, cars assembling ont he top level of car park, Westfield Hornsby and heading off to Cowan at about 11:30. Apparently it is a bit like Targa Tasmania, with new and old cars entered. Should be a great day.
