Vivid racing has put together this stage 2 big rotor brake upgrade for the Porsche 996 turbo or c4s from 2001-2005. This brake upgrade includes 4 agency power plus 1 caliper brackets to increase your rotor diameter at all 4 corners from 330mm to 350mm while retaining your factory calipers. In addition to the brackets, we also include 4 brand new OEM drilled Porsche 997 turbo rotors needed. To give you better pedal response, we upgrade the factory rubber brake lines to the agency power steel braided brake lines at all 4 corners. These lines replace the originals and do not expand under pressure. To further the braking potential, we couple this kit with a set of pagid rs29 yellow brake pads. The pagid rs29 yellow pad is similar to what is used in the GT3. Its compound allows you to run this pad on the street but have incredible braking power on the track. These pads do not need to be heat cycled like other brake pads. This brake upgrade is a great away to improve your stopping power and help fill the inside of those wheels with out spending several thousand dollars on a big brake kit.
