does anyone know anything ro have experience with Roberuta kits by Topsecret?

I am very interested in these and any help would be great.

check it out!

 

I discovered this through some 240sx/Silvia guys; I've never seen it on an S2000, although I don't see any reason for it not to work.

Think of it like a "solid airbag." The intention is that under normal driving (at speed) the system is fully "deflated" and therefore completely rigid (doesn't affect handling). Then when you encounter speed bumps, curbs, dips, potholes, etc.. you can activate the system and raise the vehicle by something like 50mm (IIRC).

Brilliant idea, kind of pricey. Did you have specific questions?

 

"They are NOT hydraulics or airbags" ... then what are they?

 

they ride a srew up and down no?

 

They are more similar to an airbag, but have a rigid body. When they are 'deflated' the solid outer sections are touching and the whole system becomes rigid, thus not affecting your suspension setup (compression, rebound rates -- so long as your setup is tuned accordingly). They can then be "inflated" separating the outer sections with a cushion of air, lifting the car somewhere around 2-3 inches, providing clearance for obstacles.

From my understanding, it is not recommended to drive normally with the system "inflated," only for short distances, keeping in mind any changes in ride-height will directly cause changes in your suspension geometry (possibly causing undesired affects in handling, tire wear, etc..).

The reason they say it is neither an airbag, nor hydraulics, is because it really isn't; it's sort of a combination of the two. The system uses pneumatic pressure (air) to raise and lower the vehicle, so it operates very similar to a hydraulic system, but when deflated (under normal driving) doesn't ride on the pneumatic pressure like a hydraulic system rides on hydraulic pressure. Additionally, despite using air, it can't be considered an airbag, because, again, when deflated (normal driving) it doesn't ride on air pressure, and has a rigid outer structure, unlike an airbag's soft rubber structure.

 

So this doesn't actually turn or change the perches that change ride height on the coils correct. It is a separate system that is installed over the coilover itself. Will it affect your alignment specs at all when used like manually changing the ride height does?

 

thanks JstnRyan for your help, this is what i was looking for.

anyone know if any s2000 is running this setup?

 

When I first read the thread title, I thought "Oh great, this is probably about a JDM cupholder or some $hit..."

All jokes aside, this kit is pretty neat, but kinda pricey. I'm curious to see this installed in an S...

 

Doesn't Praxis make something like this?

 

It actually installs between the top of the spring, and the top perch. As it 'inflates' it obviously pushes down on the spring, increasing your ride height. As is the case with any change in ride height, it will change your geometry, but like I've stated, it's intended to only be used for short distances at a time, thus making any concerns about tire wear (etc..) negligible.

You could, obviously, ride with the system raised for however long you want, but you may cause undue stress on the system, and will have to take into account how the lessened rigidity will affect your handling.
