ZZP as well as other sites carry and sell the Stainless lines for our cars. Just make sure you get the extended ones for the fronts. I had the problem of the normal ones not being long enough so I send them in. When it comes to dimpled/slotted rotors, i feel that they are unecessary and only cosmetic. I personally am running HAWK front and rear and will never run anything else. They are amazing.
I'm going to need brakes in probably 8-9 months and wondered what everyone else is running on GXPs. I was thinking of running Hawk ceramics front and rear for pads and EBC slotted and dimpled rotors front and rear. Also does anyone make SS flex hoses for GPs?
