As Sarnie has said Redstuff better than OEM but also harsher on the disc.
Ferodo DS2500 is a widely acclaimed pad which gives outstanding performance consistently,especially on track, something the redstuff cannot cope with.
Mintex Extreme is basically rebranded 1144 and sits in between the redstuff and Ferodo in terms of performance but again is a little harsh.
As a trader we supply all brands.
From a financial point of view as a seller I would push EBC all day long as we make more money out of them but hand on heart as far as performance is concerned the DS2500 wins hands down.
We do road test all products before we offer them for sale, always sceptical on sales pitch.
