I believe so.
I've only changed a set of standard shocks to coilovers, but the process should be the same, just won't need to set your ride hight as it has adjustment collars.
I was surprised at how easy it was, when I was doing it with my mate (a mechanic). I'm sure there are a few people with the know how on here to ask if you get stuck.
My top tip would be to give everything a clean and a soak with wd-40 or penetrating oil before for a few hours before you get started - will make the whole process a lot easier.
Oh and make sure you get your car cambered and tracked afterwards - you don't want to munch your expensive tyres!!
