Lowering springs

[1skinner1]

Hi all I'm a newbie to clios, just got given lowering springs don't know the make jacked car up and sat it on axles dropped the rear beam pulled out a spring, are lowering springs the same shape as standard springs I.e small both ends, as the lowering springs are big one end small the other, if that's right does the bigger bit go at the top and small bit on the bottom? If I was to put the springs on rear and not do the front will the rear still lower or look the same until the front is done? Cheers
