I didn't realize that the 2009 C2 has the same 13" rotor diameter as the C2S. Just checked it at my local dealership! WOW!

I was told the thickness differs between these 2 rotors and they are not the same with 09 models.

Be careful because the C2 has smaller brake pads
then the C2S. I had to send the brakes back once.

Sure?
I do not know if spec sheets I've seen are accurate, but I have seen the 'S' listed w/rotors at 13"......non-S at 12.5.
Order guides list it that way also.
Possibly both are wrong.

Lets clear this up, because there have not been a lot of facts printed about this.

The 2009 Standard Carrera has front discs which are 330MM in diameter, and which are 34mm thick. That is an increase from the 2008 model of 12mm in diameter.(1)

The rear of the 2009 standard carrera now measure the same 330mm in diameter as the front, up from 299mm in the previous model.(1) These discs are 28mm thick. theses are now 4mm thicker than the previous model as well.(2)

The brake discs on the 2009 Carrera S are...identical to the standard Carrera. 330mmx34mm up front, and 330mmx28mm in the rear,(1).

The difference between the Standard car and the S for 2009 is solely in the caliper. The S has red ones...and they are of a different design, which I would GUESS is a stiffer design for even better brake feel. But I really don't know, as nothing I have makes any reference to the difference other than what I have written. There is NO mention anywhere that the pad size is different on the S vs non-S. It would not surprise me to find out that they have different part numbers though, as they each have a different caliper design, and possibly pad material is made for a higher temperature on teh S than the standard car, but this is pure speculation. I would love to have a photo comparison. Perhaps as we get into track season, and people start changing their pads we can see something like this.

Hope that helps.

Michael.

Stop confusing us with the actual facts. Its more fun to speculate.

Good job!

Michael....thanks for help in clarifying.

For what it's worth....here is a current 'S' front.

Love the open caliper design of the 997.1 and .2 S brakes, can't stand the closed top caliper design of the 997 GT3 and 2009 C2. Makes changing pads very difficult. To me, that's a big plug for ordering the S - that is if you track and want to be able to swap pads.

adfsouth

Agreed.....I can swap out my wheels and pads in 40 min....so easy.

Michael Russell

Just for comparative purposes, here is the front brake assembly on my 2009 Carrera:





It does look like it will be annoying to change the front pads, (or rears for that matter). But, certainly not a reason to spend an addition $10,600 to get the S. My time is valuable, but not THAT valuable!

I agree, I wouldn't pay $10k for different calipers - I'd do it for PASM, 19s, the 3.8 DFI engine and the caliper design is a bonus Porsche sure has closed the gap in the 997.2 between C2 and C2S (xenons now standard, rotors same size, etc.).

mdrums

Changing pas out for the track will be hard for the standard Carrera. I love the S calipers because pad changes only take 1 minute.

I will say this; I have owned 911's in the past and part of the allure of the car was the braking. The 911 has never been the fastest car out there but it could out brake almost everything on the road. When I bought my 997 I didn't think so much about the engine displacement, I mean really are any of us going to get the difference between the 3.6 or the 3.8?? Maybe, But what I didn't get at the time was the significant difference in the feel of the braking between the c2 and the cs2 I applaud Porsche for bumping up the brakes in the 997.2 it is the one thing about my 997 c2 that I wish was a bit more like the old 911. or the the S
