The Porsche 928 S2, a grand tourer celebrated for its blend of performance and comfort, represents a significant era in Porsche engineering. While the factory braking system provided adequate stopping power for its time, enthusiasts seeking to elevate their driving experience, particularly under demanding conditions, might consider upgrading to carbon ceramic brake (CCB) technology. This article explores the engineering characteristics of CCBs and their potential benefits for the 928 S2, focusing on thermal management and durability.
How Much Unsprung Mass Can Carbon Ceramic Brakes Reduce on the 928 S2?
Carbon ceramic rotors are typically up to 40-50% lighter than their cast iron counterparts. For the Porsche 928 S2, this reduction in unsprung weight can contribute to improved suspension response, allowing the wheels to more effectively track the road surface. This can translate to enhanced steering feel and overall vehicle agility, particularly during cornering.
How Do Carbon Ceramic Rotors Manage Repeated High-Heat Stops?
Standard iron brake rotors may experience performance degradation under sustained high temperatures, potentially leading to brake fade. Carbon ceramic rotors, however, are designed to maintain a high and consistent friction coefficient at temperatures exceeding 900°C. This characteristic can contribute to improved braking consistency during repeated high-load braking cycles, crucial for spirited driving or track use.
What Service-Life Difference Is Typical Between CCB and Iron Rotors?
While iron rotors on the Porsche 928 S2 may require replacement within a range that varies with driving style and conditions, carbon ceramic discs are designed to last up to 300,000 km under normal street-driving conditions. Actual lifespan depends on driving habits, pad compounds, and environmental factors. This extended service life can represent a long-term cost benefit despite the higher initial investment.
How Can CCB Material Reduce Dust and Corrosion Effects?
Carbon ceramic brake technology can significantly reduce the corrosive brake dust commonly associated with high-performance iron pads, helping to keep the Porsche 928 S2's wheels cleaner. Furthermore, the material is highly resistant to oxidation and road salts, which can reduce the surface corrosion visible on traditional iron rotors, maintaining a cleaner aesthetic over time.
What Construction Details Separate Premium C/SiC Brake Systems?
Premium carbon ceramic brakes may utilize Continuous Long Carbon Fiber (T700 Grade) woven into a 3D matrix with Silicon Carbide, offering a more advanced structure compared to chopped-fiber alternatives. This advanced construction enhances the rotor's strength and thermal stability. A floating aluminum hat system is typically employed to manage thermal expansion effectively, further contributing to consistent performance.
Upgrading to carbon ceramic brakes is a significant consideration for Porsche 928 S2 enthusiasts focused on enhancing their driving experience, particularly concerning thermal management and long-term durability. While offering notable advantages, it is essential to consult with a qualified brake specialist to ensure proper installation and compatibility with your specific vehicle and driving needs.
