@DannyP, I was just curious if Phil really has a lsd in his car. I’d almost bet he has a 4 Spyder super dif, and is calling it a lsd, when in reality, it is not. I agree, a 4 spider dif is all one needs for a street car. I had a loc-rite in a drag car, but that was a type 2 transmission. I don’t think they ever made a type 1 variation.
