EBC Yellowstuff is an aramid fibre based brake compound with high brake effect form cold and is possibly one of the first ever compounds that can be used for STREET AND TRACK DRIVING. These pads do not require warm up but do get even stronger under the heat of hard driving. These are not a low dust pad and if your desire is for a low dust premium street use pad, you should consider EBC Redstuff.When considering full race use, Yellowstuff has been a strong favourite, having been used for two years in the Swedish Camaro Cup and at numerous other race events where a stock caliper system is fitted.It is also the choice of 90-percent of the Mazda MX5 Miata competitors in the UK race series and has an unblemished record as rotor friendly track pad for vehicles up to 2000 lbs weight or 200 BHP.In the USA the SCCA and NASA drivershave been testing Yellowstuff with feedback and good reports POURING in from a 543 test driver major market proving event with these groups. Read that figure again 543 test drivers.There is no guesswork here.
