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!
Yep, that sounds about right. I did no precision timing myself (local restriction on a DE day actually) but I would estimate a four to five-second improvement over an 85-second lap that was clocked in the first 'mode'. And the racing 'mode' is a lot more fun too.

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The handling is set up so well and the power is more than enough that the dynamic ability of the current (or just superseded) 911 makes it a superb automobile.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!)

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

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 ...

Sounds like a fine way to explain engineering change and its management; affecting FMECA and the like...

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

Anybody able to provide what parts need to be updated for this conversion?

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 this is a very old post but have been doing lots of research as I want to install 997.1 s brakes and very interested in the final statement that the 997.2 non S and S share same hub assembly. Therefore 997.1 S and 997.2 S components can be used. Would appreciate someone confirming that brakes from c2s and c4s from the 997.1 S models are the same and can be fitted to the 2010 997.2 non s?

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.
