ACE pipe sizes and ACE spring rates

[rick130]

A quick Q, what size/diameter are the hydraulic lines for the ACE system?

Also, are the front spring rates different to the non ACE cars?

Thanks

Hi, i know nothing about spring rates but i know that the ACE pressure pipe's OD is 3/8"

when I last purchased the front ace pipe it was a different diameter to the old existing one.

Spring rates the same for ace / non ace , just shocks that are different

Maybe cos it wasn't old and rusted [smilebigeye] ... how would it fit into the valve block with a different OD?

Oh, and world someone be able to run a vernier over the front and rear anti-roll bars diameters please?

From RAVE front ACE is 35mm vs 30mm non ACE
Rear ACE 35mm
REAR Without ACE and SLS 29mm
REAR Without ACE and non SLS 19mm

Thanks Mark!

I didn't even think to look in RAVE [bigwhistle]

You sure? I know the rear shocks are different for SLS but I though ACE and Non-ACE shocks were the same.

Yep I should've elaborated , pre update ace shocks were different ( ace / non ace ) .
They rationalised and made them the same for d2a update when they changed the panhard rod length to reduce bump steer

Project rick ?

The front sway bar ( non ace ) IMO is good if you drive on well formed bitumen with no potholes etc , but the roads around here don't fit that description, and so its too stiff , I have removed one side link pin and gone for a drive ( unloaded ) in the past on my car ( a world of difference )

Yep, looking at a passive/kinetic roll setup a la the Citroen Xsara WRC car and Mitsubishi's Dakar Pajero before the setup was outlawed.

I think it's pretty doable.
One pair of hydraulic lines, one small accumulator wth a piston.

It basically unlocks the ARB's in articulation, engages them in roll all without the need for an accelerometer and pump/valve block assembly and electronics.

The only downside I can see is I reckon those bars will be to stiff, but I think I can modify the compliance with the accumulator and rams, much like you can change stiffness with a blade adjuster on an adjustable ARB.

Aren't both those systems devised from kinetic suspensions( I think its kdss now ) right here in southwest WA.
I remember going to Perth 4wd show in the early 90's and being impressed by their demonstrator on the test track.
Definitely a worthwhile project

Yep, a simplified setup, used under license.
