EBC Reds and Yellows get good feedback, EBC Greens are not up to it really, but Ferodo DS2500 gets the best feedback of the common fast road/trackday pads we have supplied.
We are testing a new heavy duty disc to worth with the OEM Toyota (Turbo) calipers and are a better way to spend your cash than EBC's discs.
They are aimed at people more interested in performance, and less interested in bling (grooves do very very little with modern pads).
