SA measures the car without the driver.

Regarding weight of 991 Turbo and Turbo S here is the very interesting fact: Turbo S weights 10kg more!

Why, since it is having PCCBs as standard? Here is direct info from my P friend:

-actual weight difference between standard braking system on Turbo and PCCB system on Turbo S(which is optional for standard Turbo) is smaller then on previous generation of Turbo(997.2) due to bigger size of brakes

-adaptive sport seats plus on Turbo S are the heaviest seat option. Buckets are the lightest, followed by sport seat plus, third are sport seats that are marginally lighter then adaptive sport seats plus. You can shave around 20kg if you order buckets or around 11kg if you order sport seats plus

-CL wheels on Turbo S are the heaviest wheel option. Optional sport classic wheels(same size as CL wheels and with 5 lug configuration which is without any doubt a huge benefite IMHO) are little bit lighter even when ordered with Gloss Black option
