Evo Corse Brake Pad Heat Shields 2004-2014 STI

If you track your STI hard, it can be a challenge to keep the brake fluid cool, as heat from braking will travel through the pads and into the caliper pistons, then to the brake fluid. Get the fluid hot enough and it will boil, leading to soft — or nonexistent! — pedal pressure and seriously scary moments when it comes time to haul the car down from speed.

Evo Corse is an Italian company specializing in competition parts. Their P-DEF brake pad plates — the acronym stands for Pyroclastic Dynamic Energy Filter — are designed to greatly reduce the transmission of heat from the pads into the brake calipers. The P-DEF plates install between the brake pads and the caliper pistons, and act as a heat barrier between the hot brake rotors/pads and the rest of the braking system. The proprietary Pyroclast material is the outcome of years of research. It boasts exceptional insulation properties as well as high compression strength.

As a bonus, the small amount of cushion provided by the P-DEF plate can reduce squealing and resonance from the brakes.

Benefits:

• Substantial reduction in brake overheating problems
• Ease in bringing brake linings up to temperature
• Increased braking performance
• Vibration damping

Installation notes: The plates install directly behind the brake pads. The P-DEF plates are only about 1mm thick, but confirm clearance before using the brakes; if there is not enough space for pads to clear the rotor with the P-DEF plate in place, you will want to wait until the pads are slightly worn, or you will want to polish a little friction material off the face of the pad to have clearance.

Imported by us directly from Italy.

Sold as a set of four plates, enough for two brake calipers. Select front or rear. Get one of each for a full-car set.

Fits all 2004-2014 Subaru WRX STI.
