|Models||Suspension type||Connections||Front trim height||Rear trim height|
|Austin/MG Metro 1980-1990 All models except Van||Hydragas||Front seperate, rear connected side to side||327mm ± 10mm at 17°C||321mm ± 10mm at 17°C|
|Morris Metro 1982-1985|
Austin Metro 310 1985-1990

|Trim height is measured from the centre of the wheel straight up to the wheelarch. Tyre pressures should be correct, the vehicle should be parked on a level surface, unladen but with a full petrol tank, and spare wheel in its correct storage position. For a half full fuel tank, it is suggested that the rear ride height should be 3mm lower, and the front 1mm lower. The vehicle should not have been driven for at least two hours. Put the steering straight ahead, bounce the car a few times, allow it to settle and then roll the car forward about a metre. Then measure the trim heights. They should be within the specifications above, and One side should not be any more than 10mm different to the other side.|
There are two valves for the front, located on the displacers themselves on each side of the engine bay (click on the photos below to show a close up of the valves).
The rear valve is underneath on the left hand side of the car (exhaust side), accessible in front of the rear wheel.
Nitrogen gas pressure:
Front: 22.4 bar ± 0.45 bar (325psi ± 6.5psi)
Rear: 15.86 bar ± 0.32 bar (230psi ± 4.6psi)
