Because the torsen will spin one wheel under some circumstances....

Please describe the situations under which a Torsen LSD will spin one wheel.

One wheel in the air, one wheel on ice type of situations

Okay, so assuming you are on a warm, dry and smooth piece of road and you are driving in a straight line, can anyone tell me why the LSD is better than a Torsen? I'm seriously confused.

If one wheel is in the air or one on ice, the wheel in the air or the wheel on ice will spin and the car won't move.

The main benefit of the Torsen is, No Clutches to wear out, In a straight line the TORSEN and LSD should perform the same,

The Torsen isn't a locker so it's just like the LSD in that both wheels need traction to 'lock' the diff otherwise it turns into an open diff just like the LSD.

I've DD'd Torsen LSDs for 8 years, with plenty of time on ice. Both tires spin, all the time, as long as they're on the ground. Torsen LSDs send the power to the tire with the grip, progressively.

Only if there is absolutely 0 traction at a wheel would one wheel spin and the car not move. Even ice has enough sticktion to get the Torsen to do it's thing.

Is Traction-Loc a type or brand of differential? I just assumed it's Fords marketing name for posi trac.

My 2019 non PP car with an A10 came with 3.55 gears stock.

This is essentially correct. It's a plate style LED and Traction-Lok is the Ford trade name they've used forever. It's the same basic design they've used forever, too. Ford Performance sells carbon fiber diff plates that are probably your best off-the-shelf option to increase lock. The other option is just sticking some sort of locker in it for drag use.

Do you have a part number or a link? All I can find are for the 8.8 not the 8.8 super.

I don't. I can tell you the diff plates in my 3.15 plates are the same as they've used forever. It might be worth popping the cover off one of those higher(numerically) ratio models and taking a look. I'm going to be very surprised if they've changed the diff internals.

Have you installed the plates you made?

I was playing with them this afternoon. They fit, I'm just mucking around with the preload heights.
