Porsche 911 996 Turbo and C4S 2-Piece Brake Rotor OEM Replacement (52386S)

Fitment for the following Vehicles: Porsche 996 Turbo, C4S With a Tri-Symmetrical design and a black Alumalite™ center hat, DBA’s 5000 Series T3 2-Piece Rotors are designed for extreme stopping power on the road and on the track and complement the looks of any performance car. As with every DBA rotor, the 5000 Series Rotor bolts right onto the vehicle with no mechanical changes needed. DBA's mid-series, enhanced-performance, slotted rotor features Thermal Stability Profiling (TSP) for improved heat handling and Thermo-Graphic paint markings for effective heat monitoring. TSP is a proprietary process specifically developed by DBA for improving the performance of disc brake rotors. Benefits of TSP include: Improved fatigue resistance to minimize surface cracking Reduced rotor fatigue during prolonged heavy braking Quick replacement, minimal 'bedding-in' of rotors Thermo-Graphic markings are placed on the outer edge of each DBA 5000 series disc rotors and are used to monitor the core temperatures achieved during braking application. The markings change color as the rotor heats up to alert the driver to rotor temperatures that exceed optimum levels. Initial Color When rotor exceeds this temperature... The color will change to...   458°C     550°C     630°C   "Kangaroo Paw" is a patented, high-tech disc rotor ventilation system designed and manufactured in Australia by Disc Brakes Australia and available on rotors for select applications. "Kangaroo Paw" technology delivers significantly improved braking performance. Even under extreme braking conditions. Kangaroo Paw rotor designs run cooler, are stronger, and outperform traditional straight-vane disc rotors. The "Kangaroo Paw" design features a series of 144 diamond- and tear drop-shaped pillars and columns individually spaced between the rotor faces. This system provides two key advantages. First, is the ability to cool the rotor faster than ever before. As the disc rotor rotates, aerodynamic turbulence around the individual pillars and columns is generated, increasing the force of hot air out from within the internal areas of the rotor. Second is increased dimensional stability across the disc rotor directly achieved by the individually spaced pillars and columns. These advantages increase the disc rotor's efficiency by as much as 20% when compared to conventional rotor designs. A 20% increase in disc rotor efficiency directly translates to reduced brake operating temperatures, brake fade, disc rotor stresses, disc thickness variation, run-out and shudder. The 5000 Series T3 2-Piece Rotor’s Tri-Symmetrical design dampens the vibration noise while providing a quieter, more responsive and smoother brake pedal feel. Along with an increased number of out-gassing exit points for brake pad friction gasses to escape, T3 Rotors offer enhanced consistency and effectiveness with every stop. Manufactured to QS-9000 quality standards using premium grade materials with XG-150 high carbon alloyed iron and dense metal matrix, the rotors are designed to provide long wear and safe, consistent stopping power by responding to the TSP process that stabilizes the micro-structure of the rotor. All 5000 Series T3 2-Piece Rotor's feature an Alumalite™ center hat designed using 061-T6 aircraft aluminum material. This lightweight hat reduces the unsprung weight while minimizing the heat transfer to the vehicle’s center wheel hubs. Tri-Symmetrical slot design results in a quieter, more responsive and smoother pedal feel. Slots continually de-glaze the brake pads improving efficiency and reducing rotor scoring. Slots even out-wear across the brake pad faces, increasing the effective contact area and extending rotor life. Slots help dissipate water when driving in poor weather, as well as pump away dust and dirt. Slotting also combats "out-gassing," where gas (from the pad bonding agents) can form a cushion between pad and rotor, greatly reducing braking power. DBA rotors are chosen as Original Equipment on many vehicles. BRAKES ARE A SAFETY CRITICAL PART OF A MOTOR VEHICLE Brake components should be installed by a competent mechanic in a professional manner. Any incorrect installation of brake components can cause a major safety problem or an accident. If you are not a competent and qualified mechanic you should not attempt to install these products, but should take the vehicle to a vehicle dealer or competent automotive mechanic for their installation. In some cases, servicing or replacing brake hardware at the time of pad or rotor installation may also be required. Disc brake pads and rotors are wear items and as such, should be inspected regularly and replaced as necessary. Street and Highway Use Brake pads should typically be replaced when approximately 1/8" to 3/16" of friction material remains on the steel backing plate. Brake rotors should be replaced before their thickness has reached the prescribed "Worn Rotor Minimum Thickness" limit (expressed in millimeters) engraved on the edge of the brake disc. Plain brake rotors may be turned on a brake lathe to remove scoring and to true the disc surfaces until this minimum thickness has been reached. Drilled and slotted rotors may not be able to be turned and should be replaced if they become scored. Track and Competition Use Due to the extremes of heat and pressure encountered by brake systems used for track and competition applications, all brake system components (pads, rotors, calipers, lines, hardware and fluid) must be compatible and should be inspected between sessions. Brake pads and rotors should be replaced before they reach the wear limits described above.   “From cast iron to the finished product – total control” DBA XG-150 Cast Iron After decades of design and development with race teams around the world, Disc Brakes Australia developed a proprietary cast iron ( XG-150 ) for use in all of it’s premium performance disc brake rotors. This specially formulated iron is rich in carbon and alloyed to produce excellent thermal characteristics, which is a key factor in the production of the casting, combined with our patented Kangaroo Paw ventilation design. With it’s supersaturated solution of carbon in an iron matrix, the excess carbon precipitates out in the form of graphite flakes. The morphology of these graphite flakes provide excellent thermal properties, increasing the thermal shock resistance and allowing it to survive rapid thermal cycling with core-heat levels of approximately 700oC and above. Coupled together with DBA’s TSP™ process, where the cast iron is stress relieved during the manufacturing process; the XG-150 cast iron structure is ideal for heavy braking and perfect for motorsport applications. XG-150 Features & Benefits Feature                                       Benefit High thermal conductivity       Reduced brake fade, improved heat dissipation. Consistent brake pedal feel   Low modulus of elasticity       Reduced tendency to distort, reduced risk of brake shudder
