I am sorry you have not had good luck with the EBC pads. The HH pads will achieve full braking ability right away if you employ the recommended Bedding In Process. I believe this is true of any Sintered pad, regardless of manufacturer. Organic pads do not stop as well or last as long. But they do not require a bedding in process to achieve full stopping power. But even without performing this process, Sintered pads stop pretty well right out of the box.
There is a chance of noise with any brake pad. But we have found the EBC HH pads to be as quiet as any, and quieter than most. Not saying anything against the Brembo pads. They are a quality product. Though I believe the originals are an organic compound, you can get Brembo pads in a Sintered version for the Spyder as well.
Sintered pads, again, regardless of manufacturer, will be more aggressive on the rotor than Organic. This, after all, is how they achieve superior braking performance. But I have never seen anyone wear out a rotor having used Sintered pads. I have replaced a good deal of rotors. But always due to warpage or metal on metal contact with brake pads which were not replaced when they should have been. Even with the softer, stock BRP brake rotors. I do not see rotor wear as a real world issue. If you spring for the EBC rotors. They will add additional braking, resist warpage better than the OEM rotors, and are of a higher carbon content steel which also resists wear better.
And lastly. You can get EBC pads for the Spyder in an organic compound. They are less expensive than the Sintered version, and work as well as any organic pad. I used to carry them. But every customer asked for the best stopping power they could get. Which, when you boil it down, is what any brake system is all about. This will always be a Sintered product. No one wanted the Organic pads, so I quit carrying them.
Again, not trying to bash Brembo in any way. Just trying to clear up some things regarding the EBC product.
