I have used EBC (English Brake Company) before, just not on the XFire. There's 3 grades, Greenstuff, Yellowstuff, and Redstuff. I only used the Greenstuff because they were the cheapest and I just wanted to get rid of brake dust which they did terrifically. EBC is a good pad, I would assume that the only difference between a Chrysler Concorde and Crossfire is just the profile of the pad. The friction material would be of the same composition and thus the same result.
