In addition, there is so little braking power applied at the rear that the stock setup is probably just fine to handle the load. 75/25 is a very poor distribution for a sports car, but unfortunately you really can't avoid that kind of distribution unless you go to a RWD/AWD platform.

I would like to share my experience.
I put in my car the Tarox kit (6 piston caliper, disk size is 330mm vs the 286mm stock size), an italian brand like brembo, but little cheaper:
TAROX - sets - SPORT
I changed the pads with a very quality pads (carbon lorraine RC6) with a very impressive improvement in the braking.
But with this setup the rears has a lot of problems with a poor traction, I felt a lot of oversteer during hard braking in the track.
So I was thinging to change the rear caliper with some others, but before this I tried to change just the rear pads (stock disk) with something more aggresive (Ebc yellow).
Surprise!
The rears became more "controllable", no oversteer and with all the grip you need also in the track.
Sorry for my bad english, I hope you can understand what I says
