EBC Yellowstuff front brake pads (part number DP41854R) are listed for the 2009-2014 Mini Hardtop 1.6 Turbo John Cooper Works. Owners on user forums group Yellowstuff with light-track and performance-street compounds, and describe it as an aramid (Kevlar-type) fibre compound with ceramic particles. Its cold bite and fade resistance make it a step up from stock pads for drivers who push the JCW harder on fast road runs or occasional track days. Friction and temperature figures vary between sources, so confirm current specifications with the manufacturer before buying.
