Anyone ever used these in their AE86?
anyone have any? I would like to make a set up, need some pics, measurements and so on of what they look like.
how well to they work?

Are these the things drag racers use to minimise axle tramp? If so, they're BAD BAD BAD for handling!
If not, just ignore me.

Yeah someone on this forum had that setup in a Sprinter. I think a lot of it came from Whiteline.

Hmm wonder if that'd fit an RA28 diff... Or probably best just to have it made to spec.

as they say on that site, these are just to relocate the lower arms of the 4 link to regain the stock geomtrey of the lower arms, after the car has been lowered.
what happens to the upper links? will there be weird geomtry happenings or diff rotation when you move the upper and lower mounting points apart?
from a legal point of view, brackets and shackles on suspension mounts and components are frowned upon

There was a thread(read argument) on this awhile back on these forums. In the end, the best option was to use adjustable arms.

thanks all.. this is the sort of info i have been looking for!
while my car does not axle tramp.. it has not been lowered much.. i plan on lowering it a fair bit more and stiffening up the rear so i feel that i may get the tramping prob.
So.. is it mutually agreed the traction brackets solve this prob?

What these brackets are designed to do is bring the line of action of the trailing arms back pointing towards the centre of gravity of the car. The problem with lowering a car is that while you are lowering the centre of gravity a couple of inches, you are making big changes to the effective geometry of the suspension. These brackets are supposed to restore some of the geometry after you lower it.
I keep telling people that when you lower a car you stuff up it's handling and they keep telling me that I know nothing. My car was lowered before I got it and it's handling sucks. It has all the big sway bars, stiff springs and hard shocks that "should" make it handle.
Anyhow, enough of my car. The point is that these brackets are supposed to install whats known as anti-squat. They are designed to line up the thrust line of the tyres with the cars centre of gravity, thus getting the most bite from your tyres.

Anthony, I am yet to see a suspension/handling post where you do not have a wealth of good knowledge to share!

Thanks for that, it all makes sence to me
so.. ultimatily.. best handling would be achieved by lowering the car for the lower center of gravity AND retaining the original geometry?
so the brackets would be worth while then?

The brackets are a good idea for a lowered car, however I am not sure on the legalities for a road car. You might have problems with road clearance depending on how low they sit. It looks like a much better option than moving the chassis mounts though.
By the by, don't get these things confused with the big chrome plated tramp bars you see on leaf sprung drag cars, they are for a very different problem.

Are these similar to RCA's?

In a sence, yes
RCA's are for the front. They do a similar job for the same problem.
I hear a heap of ppl running RCA's but hardly anyone running traction brackets...

Has anyone heard of the RCA's for the front that are offset to give a bit of negative camber? a cheaper option than adjustable strut tops?

Joel, I think you are talking about the eccentric bush that is installed at the inboard end of the lower control arm. These just fix up the chamber problem. Frank is referring to Roll Centre Adjusters. These look like a spacer block that sits between the strut and the ball joint. They work in a similar way to these "traction bars" in that they change the angle of the lower control arm......back to where they should be.

Hmm I might be wrong but i'm sure i've heard of the roll center adjuster that sits under the strut.. Basically the offset is changed between the bolt holes on the top of the RCA, opposed to the holes on the bottom. So I think the holes at the bottom, if they were closer to the center of the car, it would add neg camber? Or am I way off here?

Yup they can be manufactured to do this as well. It would just be a custom manufacture for your specific geometry. I would assume that standard aftermarket RCA's (if there is such a thing) would keep the chamber at the same angle and just adjust the roll centre.

Roll centre adaptors, with camber.
http://www.battleversion.com/rollcenter.html
But these would do something strange to your scrub radius would it not? Depending how much camber you get out of them, you'd get a change so that a car setup with negative scrub radius would go positive. You get toe out under braking with a Positive scrub radius, i think.
I've seen a version that has a different spacing on the outer holes to allow a celica/cressida strut. Would be idea for us with Aus spec sprinters, easy way of getting decent brakes and some negative camber. Anyone wanna make them for us? I've got pics of them on my PC. If you wanna see, pm me your email.

Traction brackets sure did - the car feels much more like a go kart than before, on the whole I'd have to say they're a good thing. Definately lowers the roll centre!
As for the upper arms, I wouldn't bother unless you've got a problem that NEEDS them.
