I wonder how good the suspension refinements could be if they are not even listed (in the PDF document) as an improvement among the list of "New for 2009" features.
New for 2009
Though the 2009 911 Carrera and Carrera S Coupes boast several important
refinements over the 2008 cars, the cars carry the same internal 997 designation as
their immediate predecessors. Chief among those refinements are new, more
powerful and fuel-efficient engines and the availability of Porsche's seven-speed
double-clutch transmission, the PDK, in place of the optional Tiptronic S.
Other critical changes include larger, more potent brakes, a revised Porsche
Communication Management system with Bluetooth connectivity and available voice
commands, a fresh exterior with BI-XENON™ headlights, and light-emitting-diode rear
lighting.

.2 car front end does not 'pogo' over bumps nearly as much and the whole feel of the car is much 'quieter' while delivering better grip in quick weight transitions

Have you looked at the 997.1 and .2 suspension on a rack, next to each other? The geometry differences are not discernable with the eye. There may be shock and spring rate differences, and fluid filled mounts and such, but there are no real changes in suspension geometry. My C4 cab does not pogo, feels planted, and yes I have driven a 997.2 C2S also.

Bruce,
they revised the entire suspension layout on the 997.2 cars.. I watched a video somewhere where they had them both on a lift and a Porsche engineer was explaining how they upgraded the control arms hubs and shock mounts.
I think it was a product overview class for Porsche dealerships service center.
In a nut shell the 997.2 has a complete powertrain and suspension package revision from the 997.1. It also has an interior and PCM upgrade.
Very big differences just on the engineering side not on the cosmetic side..
I like to think of it as part 997.1 and part 991.1

Why would anyone want to buy a 997.2 vs .1 when all you get is an updated NAV.....
I can barely tell the difference cosmetically and I know what the differences are. I bet if you gave an uninformed person 10 mins to look at the 2 side by side that they probably couldn't tell
Sure a few extra horses would be nice but it was hardly a ground breaking move
Besides, the 997.1 sounds sooooo much better!!

don't kid yourself as they have completely different AWD systems.

I wonder if the 991.1 guys are going to have this debate with the 991.2 guys
And than say how their outdated 9A1 engine sounds better, how the rear steering doesn't matter, how the electronic rear diff isn't a big difference, or they don't care for the new LED rear lights
But hey park them side by side no one can tell difference between a 991.1 and a 991.2!

The AWD system weighs more. They have new shocks, SPASM available which I have, springs, mounts, control arms, hubs, half shafts, and brakes...
BUT WAIT THAT IS NOT DIFFERN'T SERIOUSLY
Oh and I suppose you think your car is the same as a 997.1 GT3 too

Mounts, rates, etc, yes, but not an entirely different suspension layout at all. Now we are in to the weight of the AWD ? If you say so.

because a GT3 or Turbo doesn't have entirely different suspension layout.
You know being the platform is the same..
so there you go enjoy

997.2 is the title of the thread.

Here are the reasons of why I shelled out extra $10K for my 997.2 C4S vs 997.1 C4S last year (not in order of preference):
1. Easier oil change on .2, you don't have to lift the car to change the oil filter.
2. Bigger brake than .1 on non-S cars. And all .2 calipers has been strengthened.
3. Revised suspension. The .2 seems to dampen the higher frequency bumps better than .1
3. C4S and all 4's now comes with mechanical LSD. This is a big ticket item.
4. Electronic F/R differential that reacts faster to driving conditions (so they said).
5. Ventilated seats are finally available. Very important here in CA.
6. New PCM including the available Bluetooth, larger screen, available iPod integration AND Sat Radio.
7. No more IMS (I think this was the biggest reason).
8. DFI (better mileage).
9. Better looking standard wheels (IMHO)
10. LED lighting all around + the available adaptive cornering lights (I love it in my BMW).
11. I liked the black keys (.2) better than the silver keys (.1)
12. I love the silver painted front air inlets on .2 4S's
13. I almost forgot the 30 extra HP. It's nice to have some extra power.
14. Bigger side mirrors. What can I say, I am old and bigger mirror helps.
