Guys I've had and enjoyed my 993 c4 cab but I've decided to go for a 996. My question is this, which one would you guys go for and why?
I'm leaning toward the C4 but any thoughts would be appreciated.

C2 is all the car you'll ever need.

C4 of course...

By repute the C2 is very grippy, lighter and a better car for track days. The C4 however is gifted with PSM - the 4wd version which is aymayzing - that for me would be the clincher...in the real world a C4 PSM equipped should be a wonderful car is almost all circumstances...

Agree with Don.

I can't believe how much quicker PSM-equipped cars were around a waterlogged Silverstone last year at the PCGB track day.

We're talking EVO VII standards of physics-abuse in a much more wine bar palatable package.

In either 2wd or 4wd PSM is Porsche Stability Management. Its much more than plain old traction control. Traction control simply closes the throttle and hopes traction will come back...

On 2wd cars PSM monitors the trajectory of the car using its inbuilt sensor (weird square thing filled with little ball bearings rolling around inside little globes) and the ABS wheel sensors and if it find it is substantially different from the desired trajectory (from the steering IIRC) which means the car is sliding - it brakes the opposite wheel to the slide. In effect its "electronic opposite lock".

That's on 2wd cars.

On 4wd drive cars it has even more options. It can modify the power division between the front and rear wheels... In normal driving its something like 90% rear and 10% front but PSM can divert things (IIRC) to about 60% rear 40% front. This, in combination with the other capabilities and the ABS system is an almost unbeatable level of driver assistance.

And its costs just £1K.

It does NOT step in before its necessary.

You CAN switch it off. But even on track - you won't want to. Unless you have seriously banjaxed things up it won't be necessary - due to the amazing grip of the car - BUT in the piss wet/snow/nastiness it could save your life - and on track it could save your insurance!

Once I knew what PSM did I simply had to have it. Once I found out how it worked with 4wd cars I've been hankering after one of them...

Sheer engineering genius.

..i agree with previous post. However that is in the wet, i have a 996 c2 and on a dry road/track there is plenty of traction and a c2 will be quicker than a c4 albeit only marginally!

Not sure about the looks of the cab. esp on the 996, has a bit of a big bum look, but that is only my opinion.

Enjoy whatever you go for my friend, you'll not be disappointed with either

Coat duly collected

Actually the BoxS is damn fine in the wet before the PSM kicks in and does its stuff - which, at least, it as has the decency to tell you about - so you can feel a proper knob/cheat/feckwit as the car picks you up, dusts you off, and asks you to promise not to do it again after standing by the door quietly for twenty minutes!

I like to think, these days, that as total amateurs go I am beginning to learn something. But the car is still better than I am - I have no doubt about that...

Are you intending to use the 996 Cabb everyday?

PSM would appear to be a useful option on an everyday car ie one used in rain/hail/sleet etc, but if you are only planning to use the car as a sunny day/weekend toy, I would opt for a C2 and not worry whether it has PSM or not. C2 is proberbly lighter and therefore slightly quicker I would think.

Do porsche do traction control in the normal sense or is PSM the porsche version?
Again thanks all.

pre facelift the C2 weighs in at about 1320kg, with the C4 coming in at 1430kg, with the cab being even heavier I would think.

that sort of difference has gotta blunt the performance in some way !!!

By inference you are not buying the car for hardcore track days..(its a convertible!))

Just go for a 2-it has much better steering and feels more nimble....

You're right it's not track days that I'm worried about just me making a mistake in the wet after the 993 C4.

PSM is the Porsche version - on recent/new cars. Previously to the wonderful PSM system they did have a "regular" Traction Control system that worked in the traditional way off the ABS sensors and the "drive-by-wire" throttle.

I think older 996s and Boxsters (pre 2000/2001 ish) might have it - you'd need to check.

If you are an average driver intending to "put" the car into corners I would buy the 4WD version. The difference in weight is more than offset by the confidence with which the 4WD & PSM will allow you to drive. The C4 will be quicker in real world driving. Add a bit of rain or crap on the road and the decision is even easier.

I am convinced that even the base C2 without PSM has some sort of electronic "angel" keeping you on the straight and narrow.

There are times when I swear that it wasn't me who corrected a slide. I just keep my foot in and steer into the slide - the car seems to do the rest (I don't have PSM - at least there's nothing on the dash to suggest this).

Anyone able to confirm this?

I had the same dilemma myself recently and after speaking to my mechanic he informed me the C2 keeps tyres much longer, or in his words, 'you need deeper pockets with a C4'. I am perfectly happy with my choice of a 99 C2 cab Tip. It feels nimbler than the 2 other c4's I drove and is slightly cheaper too. I paid £39999 with 26k on the clock
