XG Brake upgrade

Just joined WA Sporting Car Club and intend to go out to Barbagallow for a few tuning days soon but I've been told that the first thing you find out when you get on the track is how inadequate your brakes are.

Mine are stock at the moment and I am wondering what my options are as far as upgraded callipers/rotors. My workshop manual says that the brakes are almost identical to the ED sedan/wagon but with a different mounting setup but I'm not going to assume that this means they are interchangeable.

Any input or past experience would be great.
I'm not aiming to have the best brakes in the world just something more up to the task, and i'm going to leave the rears alone for now.
