gaz suspensions fore the elise

[mico]

I Hawe just receved a set of Gaz suspensions, purchaced on the Ebay fore my elise S1.
There is no instruktion whit them, so I dont know whits way to turn them??? springs up and adjuster down ore the other way around?
I hawe send an email to the company making them, no ansver, its a week sins now!!!
Please can eney one help me out?
Do eneyone hawe experience whit the adjustment on the Gaz??

Kind regards mico Denmark

i read a thread on those gaz items a while back sorry to say it but you've been had there not very good quality an the company seems to have a sell an forget attitude to them

Sorry to say they are poor quality.

If you fit them, the damper body MUST go at the bottom (opposite to the Konis which are invetred).

Because the internals are so simple the Gaz cannot be inverted.

The Gaz have to be run with the adjuster at the bottom. They are a copy of the old AVO design and cannot be run uside down , as they contain air in them. They are very cheap (and not chearful). I bought a set for an old mini and the dyno chart they came with showed one was over 20% different from the other. Hardly confidence inspiring. Needless to say they went back.
A wise man once said that the bitter taste of poor quality long outlasts the sweet taste of cheap price.
I say that I am not rich enough to buy cheap products.

Almost all dampers run best with the rod at the top and the body at the bottom. I've only got limited experience of Gaz but they seemed fine for a budget damper, and worked rather better than the Spax and AVOs I tried before that. They have a relatively high nose load and rather harsh damping compared to the more exotic dampers such as Nitron or Ohlin, and this might be more important to you given the relatively light weight of the Exige/Elise?

err - no!

Twin tube dampers *have* to run one way up as they rely on gravity to keep the oil in the right end...

so called gas dampers have a presurised gas charge to keep the oil in the right place, hence they can be mounted on any orientation.

there are some twin-tube dampers that have a small gas filled bag in them to keep the oil down thus making them less probe to this.

other problems for twin-tubes is that when worked hard, the oil heats up int he inner tube (that does the work) and the viscosity of the oil is changed, thus the damping forces change.

I've used a variety of dampers including gas pressurised twin tube and monotube designs. Even the gas pressurised twin tube systems that claimed to be invertible only worked reliably one way up. Unless you have a remote reservoir system or the manufacturer explicitly states that the unit can be run inverted, I would always fit it with the rod on the top. This is the conventional way up, all the dampers I've tried so far have worked OK this way up, not all of them have worked inverted. The Gaz dampers I tried didn't claim to be invertible, but this was several years ago and things may have moved on since then.
