i never needed more than my 300z brakes on lowes motor speedway.

i have metal matrix ie stock hahah pads up front and auto zone pads outback.

the brakes will make you spit your food out your mouth. so i dont think you should look for big rotors just yet. oh and the 300's are on my 3100lb S14. your 2700lb s13 will be wonders better.
