Wavetrac isn't an LSD, it's a TBD. It has no clutches in it that a friction modifier would "help".

Feeling better doesn't mean anything with respect to wear. Above when I mention that I only put my racing customers in Swepco it's because it shifts poorly when cold. When hot during racing, it better protects from wear, and doesn't shift the same as it does on the street where 2/3 of people don't even drive the car long enough to get the gearbox up to full temp.

I remember there was a time where everyone and their mother was putting Redline into their Porsche gearboxes. You'd see people raving about how good they shifted. On the service side of things, we saw what they looked like inside and they were getting shredded.
