guess I didn't read far enough into that thread. I didn't see that part of it.. I would agree with that statement, but there were other statements in there that make me wonder. It doesn't matter to me what they run in their cars. I came out of the old muscle car era. I am a stickler for what is proven. I have ran limited slip rears ends in just about every car I have owned that was a performance based car, and I hated the open diff. Damn near sold them both before Wavetrac came along. You need consistent lock up whether drag racing or cornering. Anything that can't deliver that is just ......period.
