I generally use EBC Yellow stuff pads in my Mk1 1.8 Trackday car with Millars racing brake fluid and braided lines and have always been happy with that setup, at the moment I’ve got some Roddeson pads in the front and although they work really well once warmed up they do have a bit of a tendency to lock the fronts up (no ABS on my car) which has led to a couple of exciting moments. I don’t remember ever suffering from a soft pedal or fading brakes with that setup.
