Depends on how much you want to spend... I replaced all my springs with lowered king springs and replaced the shocks in the arse end... Cost me about $350 all up, but that's installing them myself... I was getting quotes around $1000 to get it all done including new struts in the front. Btw, I'd recommend you get super low springs for the front and lowered for the rear. Mine still sits just a little too high at the front for my liking.
You can always just do dodgies with a angle grinder and chop ur springs
