by chance, are you guys running the rpm rear skid plate that goes from the chassis to the transmission case? locally people were breaking chassis in the same spot because they switches to the rpm and did not put the extra screw in that goes through the chassis and into the skid. they put the screw in and the problem went away. just a thought for you guys. i ran the pro-line kit and didn't have an issue, but i only ran it for 4 runs before i sold the car.
