In a nutshell:
-Proper brake ducts
-New ATE Super Blue Fluid
-Real Track Pads (i.e. PFC)
Don't be cheap on brakes. With a few changes, you'll be able to enjoy a brake system that is very well designed and performs very well. As for your hoses, just get the right ones. Everything else will just come apart.
If you are looking for a cheap upgrade, find a set of used front calipers and carriers from a 330. Then get a set of 330 front rotors. Put some brake ducts on them, get some PFC pads, SS Hoses and ATE Super Blue Fluid. Then you'll have a really good stopping car that will surprise everyone around you. You'll be able to hammer the brakes all day long.
