Just to add to what cre as said, you will need a set of spring compressors (as in pic below), mine where a set of cheap ones, the threads are just starting to strip. Having said that, I’ve used them on other vehicles more than a dozed times. Not a difficult job to do, the rear ones are the easiest. It’s only a question of removing the shocks. The front ones you will need to undo the top wishbone bolt, the wishbone will then be clear to gain accesses to removing the shock. You may find you will need a scaffold pipe on the end of your wrench to undo the wishbone bolt (mine where very tight) The only other restriction was the screen wash bottle (on the passenger side for LHD Supras) the bolt will just squeezes past it if your lucky.

Edit, Just one more thing: Always torque up the shock bolts with the vehicle on the ground (not jacked up)
The bottom rubber bush could distort otherwise.
