August 17, 2007—StopTech has teamed with Callaway to develop the ultimate brake system for Callaway’s most exclusive vehicle, the C16 Speedster. The made-to-order, 210mph C16 Speedster features a 700 bhp Callaway V8, custom adjustable Callaway/Eibach suspension, topless cockpit with integrated helmet holders, and a host of other new technologies. Company founder Reeves Callaway said of the car, “This is Callaway Cars’ most exquisite vehicle to date.” This dynamic new vehicle will debut on the concept lawn at the 2007 Pebble Beach Concours d’Elegance on August 18, 2007.

To drag this speeding bullet to a halt, Callaway is relying on StopTech’s new Carbon Ceramic Brake System (CCBS). Lurking behind the Callaway/Dymag carbon/magesium wheels are 380mm (15-in.) rotors with six-piston calipers in the front and 355mm (14-in.) rotors clamped by four-piston calipers in the rear. The total unsprung, rotating weight savings from the carbon/magnesium wheels and the carbon ceramic brakes is a staggering 80 pounds, when compared to an aluminum wheel and iron rotor set of comparable dimension, or 20 pounds per corner.

StopTech Sales Manager Jeff Ritter commented, “StopTech is thrilled to be associated with a vehicle of this stature, and with the highly regarded Callaway team. The C16 Speedster is the perfect showpiece for our latest technology, and we believe the discerning Callaway customer will truly appreciate what our innovative CCBS system brings to the overall package.”

The primary benefit of the StopTech Carbon Ceramic Brake System is a roughly 50 percent reduction in weight versus a traditional gray iron rotor of the same dimensions. This weight reduction results in lower rotational inertia, which translates to improved steering response, less energy required to accelerate the vehicle, and improved roadholding and ride quality. In other words, the vehicle’s ability to stop, turn, and accelerate are all favorably impacted by StopTech’s lightweight Carbon Ceramic Brake System.

The StopTech Carbon Ceramic Brake System also eclipses iron systems and competitive ceramic systems in terms of durability and longevity. Instead of using the discontinuous chopped fiber composition of competitive systems, the StopTech discs use continuous fiber construction. The long fiber structure results in greater strength, fewer strand ends to oxidize, and greater thermal conductivity and heat capacity.

All of StopTech’s four wheel brake applications using 332x32mm, 355x32mm, or 380x32mm rotor combinations are now available with a Carbon Ceramic rotor option. Existing StopTech customers with four-wheel kits using those rotor sizes can upgrade their iron rotor systems to Carbon Ceramic as well.

StopTech will also be introducing a limited range of Carbon Ceramic rotors through our Direct Replacement Kit program. These rotors will be produced in factory sizes to mate with the factory calipers on assorted high performance sports cars, such as the Porsche 911 GT3 and Lamborghini Gallardo.
