First off racing your viper has been a no no from day one and will void your warranty. Using non DC parts will also void your warranty. See the link below for more info. I believe you will find in your warranty book that racing will void the warranty.

I would contact Chuck Tator and see if he can help you.

As I have stated before I was NOT racing my car. The dealer said it had to of been abused for it to brake like that. Also I have spoken with Chuck and he said that it sounds like a dealer problem.
