The standard bumper is held on by 3 screws into each wing. These go into what are basically those little plugs you put into holes on the wall before screwing in something. They are USELESS. From this next picture you can see the plug just rips through the wings:

So instead of reusing them, i used nuts bolts and washers. I cant remember the size, i think they was 6mm or 8mm. Bolt, washer, bumper, wing, washer then nut (put locktight or get a lock nut or whatever they are called). This pic shows how someone else done it, obviously without the wing.

Its fiddly, and you will need to remove the head lights, front wheels and arch liners too! But its worth it knowing the bumper wont come away easy.
In other news i got some of those adjustable drop links through today that Jam0r put up a few weeks ago. Look great, hopefully get them on now
