Hidden Trophies.....?!?

[ya0tzin]

My GT5 Platinum trophy is within my grasp.. But, does anyone know what the Hidden Trophies are awarded for?
I've been saving the Nurburgring GTR'07 Trophy til last so I can get my platinum with a bit of style, but first i've gotta do these hidden ones. What the hell are they awarded for?!
