Ok let's see...the emergency brake still works. That section of the rotor is exactly the same size, thickness and all
It is still a solid rotor like the stock ones. Don't bet your life on it but I am pretty sure, almost positive the rotor diameter is 11.4 instead of 10.4 for stock. So you gain a whole inch there. The pad contact area covers the whole rotor surface just like stock. If you know what I mean there
um, Still haven't driven it yet so.....I will later tonight
But it fills out the wheel as much as the fronts do know.
