Some questions about the 911/991
 

Hello everyone,

I'm new to Porsche, and its going to be my first time buying a Porsche.
I'm a Audi customer, I have Audi RS4 2007 and a Q7 3.6 FSI 2009(US Version).

This week I am ordering a new 991 Carrera, from USA, but I live in Berlin/Germany, so i will ship it from USA to here. I wanted to ask few questions about 991. And I am not a millionaire spending too much money in cars :-). I saved money for a long time to get a 991, so I want to know if I really need some options that I will add to my 991.

1. What really Wheel Spacers 5mm do?
2. Is there a big difference between normal PASM and PASM SPORT? I'm not a high speed addicted driver and I will not use 991 for racing or stuff like this. I'm going to use the 991 for my daily routine(home, work, gym, etc). So do I really need to add any of PASM? Does PASM makes the driving more comfortable, like Audi's Adaptive Air Suspension?
3. What exactly is Porsche Torque Vectoring (PTV) and PTV Plus.


I would really appriciate every reply. Thanks
