So he jumped into the driver's seat and turned off the PSM but left the SPORT mode on and used the wheel-button shifters. What he showed me was probably a good 2-4 seconds better on the proper driving lines. He was even keeping up with a 997-2 GT3 on slicks (the driver wasn't a bad steerer either) but showed that fine throttle control can do to achieve the attitude control of the vehicle's rear in and out of corners. He's also one of those 'drifter' dudes and showed me the extreme end of that 'splay' that put a big grin on my chin!
In regards to the brakes, I could also qualify that I had stopped using OEM rubber a long time ago; I am using a set of ADVAN Neova AD08 street 'R'? compound tires. Very grippy but very noisy on the roads.
I figured that upgrading the brakes is an important consideration when upgrading rubber; since I will be carrying more speed and will now have a lot more traction that requires more braking horsepower.
The handling is set up so well and the power is more than enough that the dynamic ability of the current (or just superseded) 911 makes it a superb automobile. And to be brutally honest I could even go as far to say I don't even need those brake upgrades; It's more of a case of desire (don't we all?), of convenience and a sense of 'skewed' economics. (i.e., I like the look of big 2-piece rotors, easier to find aftermarket and change pads, it's only 50% more than buying the OEM rotors & pads from the dealership(!?), and I hate the standard C2 faded calliper paint going all whitish grey!)

Seriously, you do need to evaluate each link in the chain when you begin with a change in tire compounds. The R compounds produce more grip and the ankle bone is connected to the shin bone is connected to the thigh bone, and so on ad Mastercard.
This month's Excellence has an interview with the design lead for the GT3 RS 4.0 and it's a familiar story, but depressing when you picture starting a little friendly 'upgrade' to Porsches we already own. I won't bother repeating it all, but the ankle bone is connected to ...

See? That's why I paid an extra ten grand: the red paint on the calipers.

But if only it did cost just 10 grand extra. Unfortunately, on my side of the world, it costs 30-40 grand for that tin of red.

First post... have 997.2 C2. Love it. Will be changing pads and rotors soon. You reference the Porsche parts manual and a link, which shows difference between the 2 calipers (C2 and C2S). Do you mind pointing me in the right direction? thanks

If you Google:
Porsche PET 997.1
And
Porsche PET 997.2
You will find both parts catalogue PDF's.
You will see that the 997.1 2S and the 997.2 2S use the same:
Calipers
Rotors
Mounting bolts
Pads
I think the only thing specific to buy for 997.2 S is the wear sensors.
Additionally you can see that as already pointed out, the 997.2 non S and S share the same hub assembly, which means you could source either 997.1 S or 997.2 S components to do this upgrade.

I know of several people successfully changing c2s calipers to 997.2 non s. I have found some c4s calipers from a 997.1 so before I commit - would seek confirmation from someone who has carried this out. Thanks in advance for any assistance.
