Either way so extented brake hoses will be needed, As the last thing you want to do is articulate a little bit and rip off a brake hose.
Heres my view on things:
Body lift-raises centre of gravity and not much real point unless you going to fit huge wheels
Spring Spacers- cheap version of a spring lift, It is much more effectife to fit new, larger springs, unless you know how old and how many mile your current springs have done,
Lift springs, wide choice on the market gain articulation and space for tyres. you could use existing shocks with minus 2 mounts put the best thing to do is correct size shocks.
You may also need to slightly trim the rear wheel arch by doing whats known as a camel cut.
