The time the OP is running should have not overworked the brakes. If he were to run into the 1:47 or lower range, then he will really need to be getting on those binders and the stock brakes will not likely to hold up, not even with the DS2500, but stepping up Ferodo DS1.11, Hawk DTC or PFC 01, 06 or 08 would be okay.
