No, the Ferrodos are excellent and in combination with the Brembo kit they work superbly - easily the best brakes I have ever had on any car (and at least on par with some brakes I have used on certain Porsche's recently)
My point is that most people think about new brake pads as the old ones are worn and misguidedly think that an aftermarket pad will be better. In many cases this is not the case if you don't consider the caliper, disc setup combined with useage and driving style. Most people drive quickly on the road but for a daily driver as we all know the percentage of time spend with the brakes being properly used is minimal - as a daily driver and occasional fast road use the OEM pads are good and offer a good combination of value / longevity and performance. Go aftermarket and you lose the balance of these 3 factors, often detrimentally.
I cannot suggest the DS2500s in a standard caliper as I haven't a clue how they work and I can't suggest them to others as I don't know their useage and style - for me they are superb and if you drive very hard (track mainly) then you won't go wrong.
