Dude, agressive brake pads, it'll give you ALL the stopping power you need with your 4 wheel disk.

I have 4 wheel disk brakes, with AEM brake pads and slotted/cross drilled rotors, and good sticky tires (bridgestone potenza RE730's) and with a full car (4 people, and their luggage, including me and my stuff) I was able to lock up all 4 when a deer ran out in front of me while i was doing 70+ mph... thats PLENTY of stopping power
