Caliper Piston Pucks – Porsche 981, 991 GT3 / RS / Turbo / GT4 / 992 | Demon Speed

Description

Demon Speed Caliper Piston Pucks – Porsche GT3 / RS / Turbo / GT4

Replace cracked or damaged factory ceramic caliper piston pucks with a durable Demon Speed Motorsports solution designed for high-performance street and track use.

Caliper piston pucks sit between the brake pad and caliper piston, helping create a thermal barrier that reduces heat transfer from the brake pads into the caliper and brake fluid. On cars that see repeated track use and high brake temperatures, the original ceramic pucks can become brittle, crack or break.

Demon Speed developed our replacement piston pucks to provide the thermal protection required in this application while improving durability compared with the fragile factory ceramic components.

The material used in our standard pucks has been proven through extensive use in our Porsche 996 and 997 GT3 Cup caliper puck applications and has demonstrated excellent durability under demanding track conditions.

Two Puck Material Options

Demon Speed offers two material choices for our caliper piston pucks. Both are designed to replace the fragile factory ceramic pucks while providing a thermal barrier between the brake pad and caliper piston.

DSM Proven Material – Our Preferred Choice

This is the material Demon Speed originally selected for our Porsche GT3 Cup caliper piston pucks after evaluating the requirements of the application.

More importantly, it has now been proven through years of real-world track use in high-temperature racing environments. Based on our experience and testing, this is the material we prefer for this application.

It provides excellent thermal isolation while eliminating the brittleness and cracking associated with the original ceramic pucks.

For most track and race applications, this is the option we recommend.

Grade 5 Titanium

Grade 5 titanium is also available for customers who prefer a traditional motorsport material or specifically want titanium components.

Titanium offers excellent strength, temperature resistance and lower thermal conductivity than steel, making it well suited for use as a caliper piston puck.

Titanium is widely used for this application and is an excellent alternative for customers who prefer a familiar, established material.

Optional Titanium Screws

Regardless of which puck material you choose, the retaining screw can provide another path for heat to travel from the brake pad toward the caliper piston.

Optional titanium retaining screws reduce heat transfer through this path compared with conventional steel hardware and can be used with either puck material.

Recommended Maintenance

Inspect the piston pucks whenever the brake pads are removed. Cracked, chipped or damaged pucks should be replaced before returning the car to track use.

Important Ordering Information

Pucks are sold as a complete set for one caliper.

If you are servicing both front calipers, order quantity 2 front sets.

If you are servicing both rear calipers, order quantity 2 rear sets.

For a complete four-caliper car, order the appropriate 2 front and 2 rear sets.
