Not really sure thats a true reflection on these pads. A lot of good things have been said about the red stuff pads for example. Green stuff don't come into it as iirc they are not an option on the zed.
And iirc the only problem with these pads was if they had been used for track use?
totally agree, they are not as good as ds ferodo's but that is reflected in the price, for most people with normal road use ferodo's are overkill
used ebc on lots of cars and bikes and i've personally never had a problem, redstuff are an oem replacement not a track pad and as you say dave the problems i have seen are when they have been used on a track and overheated
i have seen more problems reported with endless pads than ebc
