Nope, my 18 GT has 3.55 gears and Aluminum housing.

Yep. Non PP cars.

The 18+ PP cars have iron housing and 3.55 Torsen.

I opted against the PP1 package, because I was changing the wheels anyway, and didn't want the 100+# weight penalty that it came with. My Intention was a street/strip car so it made a lot more sense to not order it.

Agree 100%. PP does nothing for me either.

2015-2017 GT’s with the 6R80 were all aluminum housings except for PP cars.

Performance Pack cars only came with the MT82.
