What year 2 are you driving? Basiclly it was concluded that 93+ Turbo brakes were the best for a normal driver. The only reason you would want to go with the Rotora's is if you are going to do some hardcore track driving. You can always pickup some brake paint and do it yourself... otherwise... you will probably pay the big brake price.
Fade typically has nothing to do with the size of brakes, it's your brake fluid that has lost its effectiveness (boiled). This is where you should start your upgrades, fluid, pads, SS lines, then rotors and calipers.
But with the right pads and fluid, you'd be amazed at the difference.
