The Rover Metro K-series’ suspension system consists of four Hydragas units. These units are linked from front to back on each side. There is more weight in the front of the car due to the engine which is why when people let fluid out the system the front always sags…the weight pushes the front down, pushing fluid to the back which compounds the problem. This highlights one of the major points to remember when we lower the car; the back on Metros is always higher than the front. To counteract this natural effect of having more weight in the front, we have to lower the car more at the back to bring it all level.
