The Porsche 718 GTS 4.0 (982) is celebrated for its balanced performance, offering both daily driving comfort and spirited track capabilities. For Porsche enthusiasts seeking to elevate their 718's braking system, Carbon Ceramic Brakes (CCB) present a compelling upgrade path. This article explores the key engineering characteristics that differentiate CCBs from the standard iron brake setup, focusing on benefits relevant to the 718's mixed-use driving profile. While the factory brakes are certainly capable, C/SiC brake technology offers distinct advantages in terms of weight, thermal management, and long-term durability.
Does Rotor Mass Reduction Affect Turn-In and Ride Response?
Yes, the reduced unsprung weight of CCB rotors can contribute noticeably to the 718 GTS 4.0's handling. Carbon ceramic rotors are typically up to 40-50% lighter than their iron counterparts. This reduction in rotational mass can improve steering feel, allowing for quicker turn-in and more responsive handling. The suspension system may also react more efficiently to road imperfections, potentially improving overall ride comfort, especially on less-than-perfect surfaces.
Can Carbon Ceramic Brakes Maintain Friction at Elevated Temperatures?
Carbon Ceramic Brakes are engineered for exceptional thermal stability, which can be especially useful during spirited driving or occasional track days. Standard iron discs may experience performance degradation under sustained high temperatures. CCB 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 and pedal feel, even under demanding braking conditions.
What Lifecycle Profile Is Typical for Carbon Ceramic Rotor Systems?
While standard iron rotors may require replacement at varying intervals based on driving style, carbon ceramic discs are engineered for extended service life. Under normal street-driving conditions, CCB rotors are designed to last up to 300,000 km. However, actual lifespan can depend on driving habits, the specific pad compounds used, and environmental factors. The superior wear resistance of the ceramic composite material contributes to this extended longevity.
How Do CCB Rotors Behave in Corrosive Road Environments?
CCB technology offers advantages in terms of corrosion resistance compared to traditional iron rotors. Carbon Ceramic Brake systems can significantly reduce the corrosive brake dust commonly associated with high-performance iron pads, helping to keep the 718's wheels cleaner. Furthermore, the material is highly resistant to oxidation and road salts, which can reduce the surface corrosion often visible on iron rotors, especially in regions with harsh winter conditions.
Material Engineering Snapshot: Continuous Fiber C/SiC Explained
Premium CCBs utilize advanced material construction techniques. These systems may incorporate Continuous Long Carbon Fiber (T700 Grade) woven into a 3D matrix with Silicon Carbide. This advanced structure offers superior strength and thermal properties compared to chopped-fiber alternatives. Additionally, a floating aluminum hat (bell) system is typically employed to manage thermal expansion and minimize stress on the rotor during temperature fluctuations.
Upgrading to Carbon Ceramic Brakes is a significant consideration for Porsche 718 GTS 4.0 owners focused on enhancing their driving experience. The reduced weight, exceptional thermal stability, and extended lifespan of CCBs offer compelling advantages. It's recommended to consult with a qualified brake specialist to determine the optimal brake pad compound and ensure proper installation for your specific driving needs.
