Uprated suspension for 90

I want to upgrade my suspension with a 2"lift for general use and offroading, can I get away with just shocks and springs or do I need to add all the other bits and pieces (dislocation cones, bushes etc). What is the general concensus?
Also what are peoples views on de Carbon equipment

britpart do a good yellow spring and gas shocker kit and so do bearmach both around£200 i think ,but may get problems with front prop

i put HD springs, shocks and rear shock droppers on my 110. that sat it a lot higher than it used to be am im really happy with how it performs.
will definatly be putting the same on the disco.
get hold of Richard at ridgeway 4x4 and tell him dan in the green 110 recomended him, should get u a good rate. he is an approved all makes stockist and im pretty sure my kit was about £300 all in, maybe a bit more, but worth every penny!

oh and thats all i put on mine and not had any problems, except i seem to eat prop uj's a bit faster than normal.
