Are you talking just replacing the pads and rotors or more than that
.
The stock Brembo rotors are very nice. Mine's a street car so I opted
for a set of Baer Eradispeed single piece rotors with drilling and I'm
really happy with those.
I use HPS hawk pads and they have been great; good stops and no noises.
I know a lot of Cobra owners that like the Performance Friction pads;
they cost less and are a tad noisier.
