Put aside the money you'll need for wheels/tyres and a remap (you will have to do this once you fit your decat downpipe).
Then spend the change on whiteline rear arb, front/rear droplinks and a set of lowering springs from eibach/tein or even get the Prodrive ones. If you want the car to stand out a little, then replace the orange wing markers, get a front splitter for it and see if you can get hold of some of the blobeye twisted sideskirts to replace the black plastic ones - makes a huge difference to how the bugeyes sit
