BOXSTER OWNERS: MAKE BRAKE FADE A FADED MEMORY Four Products Introduces CoolShims™, a Revolution in Brake Cooling

Pasadena, Calif. (January 2013)—Spirited driving is what the Porsche Boxster is all about. However, whether you carve up the canyon or take it to the limit at the track, brake fade is always a concern no matter how great the car.

Enter CoolShims™ from Four Products. Designed and tested as an economical drop-in part that is as easy to install as a new set of brake pads, the patented CoolShims™ reduce brake fade by lowering the temperature of your calipers more than twenty percent.

Mounted between the brake pad and the caliper piston, CoolShims™ conduct heat from the caliper piston to a heat sink located externally to the brake caliper through a patented high thermal conductivity dual-metal composite developed by Four Products specifically for the extreme thermal conditions found in a high performance brake system.

Testing has revealed a greater than twenty percent decrease in maximum caliper piston temperature as well as significantly faster cool down times for a caliper employing CoolShim™ technology.

“It is a simple concept, if you transfer the heat out of the caliper and into the airflow, the brake will run cooler,” said Four Products Founder Dr. Joseph R. Demers. “We routinely hear from drivers who dropped in a set of CoolShims™ and discovered that they actually work! No more fade during the final laps. Good solid pedal all the way through the race. We are excited that they are now available for the Boxster.”

All CoolShim™ products are designed and manufactured in the U.S.A. For more information, and a listing of where to purchase CoolShims™ for your vehicle, please visit or call 626-636-0507.
