Chuck, I thought I had seen some hot calipers before with Jay Lopez, but you win the prize. Normal, hard braking over time will turn the lettering yellow. Continued severe use can turn them a brown color. Although pictured in the shade in your photo, yours seem to be a color I've never seen. Obviously, with EBC, we should not have sold you anything but yellow or blue range pads to at least try to withstand your particular situation.
Honestly, my opinion would be that even upgrading to the Stoptech system may not be enough for you. Jay Lopez went with Dilusi, and I suspect you might want to also upgrade to a full 4 wheel complete modification of some type. Add whatever cooling you can, either through the Porsche style deflectors, or something like Bobby Archer's new duct system, similar to the proposed MOPAR unit, which I'm about to put on my car.
My last point would be to say that I hope everyone realizes that simply changing pads on a Viper does not provide you with a racing brake system. The EBC Blue heat range we are testing now, is a high speed, high heat pad, with a 10 wear rating on a 10 scale, good for 1500 degrees and around 400 track miles. In comparison, those reds are a "5" rating, at 1300 degrees and approximately 200 miles. But even this Blue pad, on a relatively stock factory system, is not going to solve all the other rotor, caliper, and heat problems to turn a Viper into a durable race car.
Chuck, make sure you check your suspension joint boots, and brake lines (even braided stainless) to make certain they are still in tact from the extreme heat, before doing any more driving of any kind.
