BlueStuff NDX is an intermediate race compound brake pad designed for all forms of light and medium duty racing applications. They are not recommended for extended road use but can be used on the street as well as the track. Bluestuff can be used without issue with OEM brake hardware.
Like all the EBC BlueStuffs products, this one does not disappoint. It's more expensive than other brands, but what you get is a good solid all around brake pads.
