Jake,
This is a dog-ring transmission? (not synchronized?) Is that what we're talking about here?

Maybe clutch-less shifting has some utility in a dog-ring transmission. I thought we were talking about street transmissions like a T56 or TKO or an RS600.
But the idea that our cars aren't "momentum" cars is false. Our cars driven with the skill that "momentum" car drivers typically have (which means the use of heel-toe downshifting) will be faster. If you're unsettling the car as part of getting to an apex in a turn, you're leaving tenths of seconds out there on the track.
