Endless has been making brakes for over 20 years. That in itself should mean something.
At the 2009 Nuburgring 24 hour race, 7 out of the top 8 cars, including 1st, 2nd and 3rd, ran Endless full brakes and/or pads.
I could go on about Endless for hours but I will save you all from my ranting

One set is in stock ready to ship. Please PM if interested; serious inquiries only
