No you'll be fine. The HPS stop marginally better, but ceramic is very close. Just don't get ceramic if you'll be doing any competitive driving/track/autox etc. They are great for the street since they stop well and make almost zero noise and dust.Very interested. How do the Ceramics compare to the HPS? I've had HPS's on my STi for a few years now. Will there be any issues with the different compounds on the rotors?
