I dont know what year your car is so if you are a pre 97 MY you could always just upgrade the brackets and install the 97+ larger rotors you go from 286mm all round to 298fr and 303mm rear, this is a very cost effective upgrade.
If that still doesn't do it for you and you want a BBK look install the Spoon calipers on the front, it's what I have currently and its a very good system, I also have the newer model ABS and run better brake fluid and pads.
