Looking to get in to a base 991 Carrera but before I pull the trigger, I wanted to make sure that there aren't any visible exterior differences between the base carrera and the carrera S as there doesn't seem to be any... I'm aware that the 4 and 4s have wider rear fenders..

 

Only the exhaust tips.

 

Color of the brake calipers and the 2 sets of exhaust pipes..

And the calipers are also smaller...

 

Body wise zero differences. Like others said exhaust tips dual on C2 quad tips on S. Brake calipers black on C2 red on S.

 

There is an "S" on the back of one of them!

 

Stock base wheels are 19's.
If you don't order PASM the car sits 10mm higher than an S.

 

That applies to the S as well.

 

The S has PASM as standard.
The optional PASAM-Sport [SPASAM] takes you yet another 10mm lower.
That is 20mm lower than a non S base car.

 

Thanks for the info.

 

Sorry - I misread an S in the PASM.
Founder is correct.

 

To summarize what all have said in terms of things you can see visually:

1) 19" standard - Although 20" (as is standard on S) is option and I believe required for PASM and SPASM

2) S comes with PASM, which lowers by 10mm, SPASM 20mm..

3) Exhaust Tips
4) S on Badging
5) Larger Red calipers instead of Black, however Yellow Carbon available on both.

In theory you can option your base, so that the only difference visible is the tips and the "S" badge.. (20", PASM, Carbon Brakes)

 

The exterior details on the S are much harder to distinguish... Because it's so much FASTER!

 

Lots of good info on the complete 991 line-up/specs etc...

S cars are faster because they are lighter. All that extra cash for the upgrade takes pounds away from drivers' wallets

 

In brief, unless you are a car nut like a number of us on this forum, nobody is going to notice the difference! Going for C2 and C2S is only a question of how much power you want and how many extra gizmo's you want to come without optioning them: PTV, PASM, bigger brakes, exhaust control valve (even w/o PSE), 20" wheels. Note that PDCC is not optionable on the C2 (at least according to website specs).
