I've got EVO 7 Brembo's on my car at the moment and I was wondering if anyone could tell me if the calipers on EVO X's are any difference to the EVO 5-9 ones? I've searched far and wide and all that I can see is that the brake disc is slightly bigger.

Next question, if they are different, do they have bigger pistons, and do they bolt straight onto previous model EVO's?
