The E60 already had quite an aggressive rear view mirror appearance as it pulls up behind you but as a wise man once said, 'to increase the attitude you have to decrease the altitude' and a great way to do this is to add a splitter. There's a fair few chinese abs plastic versions out there to choose from on eBay (other market places are available) but i chose the KSB kit and matching side skirts to fit to my 545i so take a look, see how we get along and see if you think it was a worth while modification.

One thing to note, I'm not a trained mechanic and I am working on my own vehicle. This and videos like it are here to serve as inspiration and to give you a clue about what's involved in performing an upgrade like this. If you are at all unsure, please seek professional assistance when fitting and upgrading new parts and above all be safe car lovers.
