Stage 4 Signature Slotted Front Brake Kit with Redstuff Brake Pads (S4KF1051) by EBC®. Get increased power with less brake dust no matter what you drive with the EBC Stage 4 Signature Brake Kit. The Ultimax Rotors add the finishing touch to this kit because the slots keep the braking temperatures down, actually improving wet weather braking which is a big deal. The anodized layer is designed to disappear in the area that the brake pads contact the rotor.
