GT3 Bumper & Center Radiator
Perhaps one of the only good fortunes of getting into a bit of trouble with the front end of my car is getting some possible upgrades out of it. I'm thinking about adding a GT3 front bumper, along with center radiator kit to an 09 C4S. No rear wing will be added (yet) and car will see a few DE / track events.
Any disadvantage to the upgrades? Cost of upgrades? Labor, including paint, as well as price of the standard bumper are all included. Anyone have an idea of out of pocket expense on this? Thanks.

Coming as an old school 911 guy, I remember in the old days (3.2L Carrera era) that the 911 aero kit functions in combination of both the front spoiler and rear spoiler.
If we just change the front, the rear will not have enough down force to balance the whole car aerodynamic. If we just add the rear wing, the same applies to the front.
I guess for road use and cosmetic purpose, it might not make much difference. Yet for track use, especially in high speed course, it might be a consideration...?
Other track gurus please chime in.
With best regards,

I laughed with the comment - "I guess for road use and cosmetic purpose, it might not make much difference". Yeah, I see many of these cars being driven for 'cosmetic purpose'.

Your observations (axhoaxho) are spot on. Changing anything will result in a reduction in safety--unless they are using a wind tunnel to crosscheck their changes.

I wouldn't mess around with "perfection". I had a GT3 and didn't care for how low the front was (scraped everywhere) nor how the rear wing obscured vision. Also, is there a 3rd radiator for the DFI cars? I thought that was a 997.1 item only.
My car (C2S without Aero) has seen 150 at Monticello and Watkins Glen and the car is rock solid and was not lacking for any aero / downforce.

Thanks for the input everyone. I do understand what is being said about the balance of forces, however, shouldn't the deployment of automatic the rear wing create enough downforce at high speeds to supplement the addition to the front? From a physics standpoint, what exactly is the downside of having extra force on the front without an exact balance on the rear?
That being said, if I did want to add a rear wing, what would I be looking at for options and prices?

For street driving adding just front aero GT3 parts will not have any safety issues in my opinion. When you start to hit 100mph in a curve on the track yes your aero will be off. Only track tests and wind tunnel tests will tell you the truth.

I think Porsche actually has a factory aerokit for the 997.2 C4S, which I am sure is tested and approved for use in all speed.
The rear wing looks pretty neat.

Consists of a new front apron with new spoiler, and new engine cover with rear spoiler and fixed rear wing. Note: significant reduction in approach angle on gradients.

For those of you who have done this conversion - how much did you pay? I just got a reply from Suncoast, and just for the bumper, it's a list of $5k (minus discount). What gives? The non-GT3 bumper is a list of $1k, and I could have sworn I've seen GT3 bumpers for under $2k before. 5 x the price for a diffuser is a bit outrageous, even for Porsche.

To be totally honest, I think your C4S is as beautiful and classy as it is, no need for any extra aerokit or spoiler.
If you really hope to do something on it (which I understand), I think a set of high-quality lighter-weight wheels (painted to your liking) will be visually and functionally better-off for your money.
Just a thought.
