But did you really find the standard brakes that bad? People they they are better than the brembo 4 pots on the Leon Cupra R.
I found the 312mm competent enough for trackdays, but wanted that little bit extra. My car is heavily modified as well, so lots of extra power.
Size is imoportant, but size is also extra weight
But it helps having the seperate bells and rotors.
Why did you feel you needed to upgrade the whole kit?
Gizmondo, it is a AP racing big brake kit I have, for ther MkV Golf GTi, and its all the standrd kit parts.
