The point of big brake kits is you're using a much bigger disk that can dissipate a lot more heat and has more friction surface. Also the caliper is stronger. What I meant was that if you want the full benefits of upgraded brakes, go all out and use the big stuff...if not you're wasting your money. My opinion anyway.
What do you mean by "the big stuff"? These rotors are almost an inch bigger. One of the reasons this setup is so great, is that you can still use 15" wheels.
Last year as I progressively became a better track driver, I reached the limit of the stock brakes after a 30min session on
street tires (azenis)! When you get on the track with race tires you can put alot of stress on the braking system. I have not had a hint of fade with this setup using good pads.
What is "mild track usage"? When I go to the track I dont putt around. I chase Evo's, STI's and Vettes
