Porsche Tech Rep Says Carbon Brakes Are Not The Best For Track Use
Porsche 911 launch in Australia, Wheels magazine spoke to Paul Watson, Porsche Australia's in-country technical representative. Watson explained that "ceramic discs can degrade if you're hard on the brakes" and that "heat build-up will degrade the carbon fibers in the disc." Rotor wear comes no matter the rotor material, though. Brembo used to promote its SGL carbon ceramics as lasting 100,000 miles. The company has changed the wording on the page to say they have "a four times longer lifetime and an obviously less brake pad wear" than cast iron discs. Your mileage would certainly vary. A little time on any Porsche forum bears out Watson's anecdote. Forum threads going back at least five years debate whether the Porsche Carbon Ceramic Brakes (PCCB) justify their new and replacement costs. 9,210 to option them on the 911 GT3. 29,000 from Brembo. And they require specific, expensive pads. For the hardcore trackie, that's a lot of cast iron rotors. The Brembo steel brake kit, for instance, is one-third the price of the Brembo carbons; an AP Racing kit is one-fourth the price. Which is why some people recommend buying a set of Brembo steel discs and storing the PCCBs until an owner resells the car, and why YouTube is full of videos of Porsche owners swapping out the carbon ceramics. On that note, carbon brakes are notoriously fragile. If the home mechanic chips the rotors, there's another mongo money repair. Carbon brake kits are lighter, look cooler, and should last a lot longer than cast iron discs on the road. They also don't create any brake dust - a good thing for J.D. Power survey respondents and the fishes. A Washington State University paper said minute amounts of copper from brake dust is killing salmon in the Pacific Northwest, as did another study from the Ecological Society of America.
Transferred from company ownership to private ownership in July 1981, the DB6 was its owner's pride and joy and arguably the love of his life - a treasured possession he looked after very well, according to the Bonhams listing.

The new 2017 Porsche 718 Boxster is a brilliant automobile, but then you expected that. Do you remember when the 550 Spyder-inspired Boxster concept was unveiled in Detroit in 1993? How about when the production 986 Boxster launched in 1996? I recall both well and I ask you because the boxer-engined roadster (hence the 鈥淏oxster鈥?name) was more of a test of tolerance and acceptance by Porschephiles than a true product launch. Twenty years and three generations later, you鈥檇 swear Porsche had planned it all this way. The Boxster turned out to be hugely popular with new and returning fans of the brand. A handful of limited-run, special editions such as the Spyder quickly became coveted cars for collectors and enthusiasts alike. The new, 4th-generation 982 Boxster comes to us with important changes that align the car with the demands and expectations of the buyer and environmental regulations. All Porsche sports cars (not to be confused with utility vehicles) have historically carried a numerical designation 鈥?that is, until the Boxster and Cayman were released.
In order to mark the arrival of the new generation and its all-new, boosted 4-cylinder engines, Porsche dusted off the legendary 鈥?18鈥?name from its racing history books and rightfully slapped it onto the current cars. Let鈥檚 get right down to the thick of what is truly important to note about the 2017 Porsche 718 Boxster. As previously mentioned, the flat-6 engines are now but a memory, replaced by two horizontally opposed 4-cylinder mills displacing 2.0L in the base car and 2.5L in the S version. I鈥檝e driven many Boxsters over the years, and I鈥檝e come to expect a certain melody when I turn and hold the key to the 鈥淥n鈥?position, on the left side of the steering wheel. With the new model, as the engine turned over, something was already off. By the time I slotted the shifter into 1st gear, my bearings no longer meant anything. The 718 sounds so very different, but moments in, especially with the optional Sport Exhaust, I quickly adjusted to the new reality.
