Micra 1.2 lx and march st brake difference?

Hey guys.
I've got a question for you.
Searched but didnt find anythink.

Are there any differences between the normal k10 1.2lx with 54ps and the march super turbo?
The st got discs on the front and drums at the rear axle, like the other micras.
But any difference?!
 
SuperS and SuperTurbo have vented discs, the others only solid. But the diamater is the same (like a mini CD :D).
I THINK the calipers all the same, they can support the thicker vented discs too.
