I have a Clarke (Machine Mart) CTJ2250LS jack (no longer sold I'm afraid) and some Clarke CAX6TBC 6 Tonne Axle Stands.
Front is quite easy as there is somewhere to place the jack to get space to get the axle stands in place on both sides at the same time,
The rear has to be done one side at a time as there's no central position strong enough to lift on.
I adjusted my rear ride height easily, one side at a time, in half a day, you need a pair of 21mm sockets for the bottom damper bolts (or a socket and a spanner) so you can pull the arm down to release pressure on the adjustable spring collars to turn them easily, mark position on base and collar and adjust the same amount both sides.
Front adjustment is just a case of getting the wheel off and using the collar C spanner to adjust, again the same amount both sides.
The hardest bit was getting the second side of the rear ARB into place, a second pair of hands and a light weight jack under the roll bar to lift it into place so the U bracket can be bolted up helped.
I fitted a set of adjustable drop links like these to the front.
