When the Callaway C16 Speedster debuted Saturday night at Pebble, another company showed off some impressive new equipment as well. StopTech developed a new carbon-ceramic brake with Callaway to help the 700 HP, 210 MPH C16 Speedster stop as well as it goes. StopTech's new Carbon Ceramic Brake System (CCBS) will be the brake of choice for Callaway, with 15-inch rotors and six-piston calipers up front, and four-piston calipers and 14-inch rotors out back. Together with the lightweight carbon/magnesium Dymag wheels, these lightweight brakes will help the C16 shed an unbelievable 80 pounds of unsprung weight compared to a more typical aluminum wheel and iron rotor setup.

The new StopTech CCBS isn't like most other carbon-ceramics on the market either. Instead of using chopped fibers like most competitors, StopTech uses continuous fiber construction for its discs. This makes them stronger and less prone to oxidation. StopTech will now offer CCBS on all of their current 332mm, 355mm, and 380mm rotors, plus existing customers will be able to upgrade their iron rotor systems to CCBS as well. That should come as pleasant news to owners of sports cars like the Porsche 911 and Lamborghini Gallardo.

PRESS RELEASE:
StopTech Carbon Ceramic Brake System makes its supercar debut on Callaway C16 Speedster at 2007 Pebble Beach Concours d'Elegance

Compton, California (August 17, 2007) - StopTech has been working in conjunction 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 700hp 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 wheels are 380mm (15") rotors with six piston calipers in the front, and four piston calipers in the rear, clamping 355mm (14") rotors. The total unsprung weight savings from the carbon/magnesium wheels and the carbon ceramic brakes is a staggering 80 pounds vs. 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 65% reduction in weight vs. a traditional gray iron rotor of the same dimension. The result is an overall vehicle weight reduction, unsprung weight reduction, and lower moments of rotational inertia. To the driver, these results translate into improved steering response, less energy required to accelerate the wheel end, and more favorable road wheel compliance. 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, less strand ends to oxidize, and greater thermal conductivity. In summary, these rotors are lighter and last longer than anything else on the market.

All of StopTech's four wheel brake applications using 332mm, 355mm, or 380mm rotor combinations are now available with the Carbon Ceramic rotor option. Existing StopTech customers 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 and Lamborghini Gallardo.
