Hey mate, its not rocket science however its not trivial either.
The perfohub setup does complicate the removal/install of the struts.
I've done both my old 225 and now my Clio 3, they have a very similar/same setup.
If you are savvy on the tools then i'd say go for it, however assume you won't get it done in a day as we had trouble both times around [for different reasons]
Also do some research, there are a few step by step guides around. I think meganesport.net has one in the how to section.
As mentioned the Clio 3 is much the same setup so a Clio 3 guide would be just as useful.
Good luck, take your time and you'll be fine.
