Bigger brakes?

Hello all! I was wondering if there was any way to get bigger brakes for my car without absolutely crushing my wallet. I found some big brake kits dedicated to the CT200h but they're really pricey and I was wondering if anyone had any good suggestions, or had gotten bigger brakes for their CT themselves? My discs are steel and incredibly tiny, so they overheat very fast when I'm driving the car hard, which really prevents me from putting down good laps at race events (Yes, I track my CT occasionally, along with autocross events too.) because my brakes get very hot very fast. If anyone has any suggestions or recommendations, don't be afraid to tell me please. Cheers
