Product Description

EBC DP42057R Yellowstuff brake pads deliver EBC's flagship high-friction performance compound for Porsche 911 (997/991), Boxster (981/982), and Cayman (981C/982) applications equipped with cast iron rotors. The Yellowstuff 3068 compound, updated in 2021 to be copper-free and environmentally compliant, provides an exceptional combination of cold-bite effectiveness and high-temperature stability rarely found in a single pad formulation. With a friction coefficient of 0.42mu maintained from initial contact through race temperatures of 450°C, these pads deliver approximately 15% improved braking effect over OE pads while remaining ECE R90 approved for street legal use.

What sets Yellowstuff apart from traditional track compounds is its ability to work immediately from cold without the warm-up cycle typically required by race pads, making them safe and effective for highway driving while still capable of handling repeated heavy braking during spirited canyon runs or track day sessions. The aramid fiber-based compound is minimally abrasive on rotors, while the medium hardness formulation provides excellent pedal feel and progressive modulation. Each pad features EBC's red Brake-In surface coating to accelerate bedding, edge chamfers to reduce noise, center line slots for gas expulsion, and pre-installed noise reduction shims for silk-smooth, quiet operation. Developed with over 60 years of friction material expertise and tested on EBC's eight dynamometer systems, these pads have earned their place as the choice of Silverstone Driving Experience vehicles and demanding Porsche enthusiasts worldwide.
