I run the C10x at our local club and in the midst of 20 associated cars it's the only one and I love it. easy to work on and Corally still has the best diffs in the business. I just bought the Mamba max 7600 and put it in, it was already scary fast but this I expect should be SICK. As for the long Corally Pinions They are great pinions and work great but I have been able to use any Pinon in the car they just mount on the end of the shaft.
