In the C4S, I do also enjoy the benefits of running 295s on the rears plus the larger turbo's brakes - which I think help offset the weight penalty a little bit.

POST 1 / ORIGINAL POSTEROriginal post

I've read that the C4 is only 50lbs heavier than the C2 and actually posts the exact same acceleration times. I'm looking for a car that I will have fun with on the track that will be a daily driver until I finish the restoration on my Trans Am. The C4 seems like the best choice from the aspect of PSM AWD for better traction over a C2. I've read however that the C4 just *feels* heavier and not as nimble as a C2. I'm even seeing TT guys getting rid of their front wheel drive they prefer it so much. I'm not going to be buying a TT but if a C4 isn't worth the preimum over the C2, I'll just save the $$$ and get a C2! Opinions? Thanks!

POST 2Original post

As an owner of a C4, the only reason I can think of that you'd want to pay a premium for it is if you're planning doing a lot of winter driving. For me, this is a daily driver in Boston, so I like the extra layer of protection the all wheel drive buys me.

POST 3Original post

I'm no expert - but did a fair amount of research before buying my C2 recently. I'm sure that the C4 is a more capable car, by the nature of all wheel traction. However, I opted for a C2 for a few primary reasons: Slightly lighter, less moving parts, presumably a tad less in maintenance $$$. 2WD has less overhead/mass in accelerating - perhaps a bit quicker. I'm driving to have fun more than to "go fast" - the C4 at the limit is probably faster - but the C2 still has endless grip - and I think you need to utilize a bit more skill to keep the car balanced at the limit (purely opinion - the C2 can push pretty hard under full throttle - I'm guessing the C4 would help pull you through the turn much quicker from the apex) Liked the stealthier "narrow-body" look - this is purely personal taste - they're all lovely to look at - in most all trim levels. So, the main difference in my opinion is in poor traction conditions (C4 wins with tons of room to spare) and in driving at the limit (C4 wins probably from outright speed carried through corners). Looking forward to others' opinions.

POST 4Original post

I bet that most here wont be able tell that they are driving a c2/c4 on dry pavement. The only way I can tell is that the c4 has a heavier steering and has a touch more feedback... thats about it... on not so ideal pavement... c4 is the way to go.

POST 5Original post

if you do not need it for winter driving, get a C2. BTW 0-60 times are always a bit lower on C2's. GT2's are all two wheel drive..quicker on the track compared to its tt cousins.

Here are the published weights. Mk 1 C2 - 1,320kg/2,910lbs Mk 1 C4 - 1,430kg/3,152lbs Mk 2 C2 - 1,345kg/2,965lbs Mk 2 C4S - 1,470kg/3,240lbs

POST 7Original post

I bought a C4S because I wanted the "S" features, but if a C2S had been available in the 996, I woulda bought that in a minute. I drive the car 2/3 street, 1/3 track-DE and love the big brakes that come with the S, but wish I didn't have the extra weight. So, like most others say, if you don't need it for winter driving, go with the C2.

POST 8Original post

If you live in Bakersfield there is no way you need a 4. The 2WD cars are a lot of fun!

POST 9Original post

To be honest, after I bought the C4S, I kind of lamented not getting the lighter 2wd alternative C2. The steering was certainly heavier, and the car felt a touch slower... However, this last weekend I autocrossed the car (my previous car was RWD) - and it was FANTASTIC!! PSM off - the car was an absolute beast. The rear was totally controllable with the throttle, and the AWD came alive at crucial moments that made me look like a far better driver than I am. I was the fastest P-car on street tires - and its not because I was the more skilled driver. Yes, the steering is a little heavier, and it requires a little bit more input that I was used to... but the feeling of drifting the car, and having it claw its way back onto the line was thrilling. My personal opinion: if you are really planning to do some DE or auto-x driving, I think the C4 would be easier for an amateur racer to drive faster.

POST 10Original post

+1 - that's good advice... I'm sure AWD can definitely be a bonus.

POST 11Original post

I'll add another quick perspective on the autocross front. If you want to be entertained and faster (Slightly), the C2 will ultimately be a little better as it will with tuning and/or tire pressure adjustments the car can be a lot more neutral than the AWD system. TTOS is one of the most enjoyable effects/dynamics that the 911 offers and can allow you to save an overcooked turn much easier than waiting for the front wheels to stop pushing as I have observed some C4's do. I would venture to say that with the weight advantage and dynamics advantage the C2 has on dry grippy surface that the C2 will be typically quicker. Let's not forget that 242 lbs (according to the data above) is a lot of weight to make up for especially if the power is the same (non power kit car vs non power kit). This of course changes to the C4's advantage if it's in the wet. The rear ends on the 996's (in stock form) are far from difficult to control as the car tends to push anyway. What is nice is when the car is neutral and then you have so many options on manipulating the car with the throttle. TTOS (trailing throttle over steer) and frankly oversteer in general is much more fun and safer in my book than understeer any day of the week. The learing curve on a 996 is not too steep. They are pretty forgiving cars compared to older 911's. The arguement that a novice will go faster with a C4 may be true but there is more to be learned and more potential with a C2.

POST 13Original post

I agree. I think there is a lot to be learned (for the weekend racer like me) on both cars, to be truthful. For sure, in the dry, my guess is the C2 will ultimately be a touch quicker. In the C4S, I do also enjoy the benefits of running 295s on the rears plus the larger turbo's brakes - which I think help offset the weight penalty a little bit. Clearly, Im no expert here, but it terms of neutrality - I was pretty impressed with how neutral the C4S felt when given aggressive steering inputs and appropriate TTOS techinque (got the **** around quicker with less understeer). I never really felt that rear-biased balance. Get it wrong, however, and the front did push. My hope is that with new drop links, and -1 degree of camber in the front, that the car will have sharper turn-in. To the OP - the best way to find out what you like is to drive both cars as much as possible. I would love to DE or autocross a C4S and C2 back to back...

POST 14Original post

Between a C2 and C4, I'd get the C2 Between the C2 and the C4S, the "S" additions make the C4S a better buy, whether for track or street. BUT..... If you are simply looking for a transition car until you get your Trans Am restored, then get the cheapest one you can find. C2, C4, C4S, whatever. That way depreciation has already hit, and you won't take as big a hit on a quick re-sell. Is the Trans Am going to be just a nice restoration show piece, or are you restoring it for track and street? Why not just forget the Trans Am, and put all your money into a GT3? As an interesting conversation or controversy point, I won our regional autocross season in novice class back in 2003 in the C4S, against all comers, including the C2. Much as I'd like to say it was because I was better than all the novice guys, I think the truth is that the C4S just made a so-so novice driver (me) seem so much better than the other guys. As a counter point, FTD for all classes was almost always by one great driver driving a 944 S2.

POST 15 / ORIGINAL POSTEROriginal post

It's not really a transition car, the 996 is going to be my DD until the Trans Am is restored then my Trans Am will become my DD and the Porsche will become a project. The Trans Am is getting a resto-mod restoration, not that it's taking much, the car is VG condition as-is. Right off the bat when I buy the 996 I'm adding the GT2 from clip, aero wing, and some side gfx and vented euro rear bumper. Then when I start driving the Trans Am, I'll start looking for a 996 TT engine or something.

POST 16Original post

Aaah. A future project car. In that case, IMHO, get a C2. Simpler, no AWD to deal with when modding, no "extras" that you may or may not want. GT3 would actually still be a better base to start from.

POST 17Original post

If you plan for a future TT motor I'd recommend you get the TT straight out of the box. - The TT motor is major expensive. - It uses a different transmission - It uses a different DME - It would not be a simple plug and play swap It will be waaaaaay cheaper to just get a used 996 Turbo up front

POST 18 / ORIGINAL POSTEROriginal post

I don't plan on buying a new crate engine, I was going to get a pulled engine out of a wrecked TT from a Porsche salvage yard. Those come with the transmission and DME. This allows me to rebuild the tranny and engine internals to the specs needed for upgraded turbos and such. Just the fact of needing to fabricate the SMIC scoops into the rear quarters and all of the IC piping make it far from a plug and play swap. Plus if I had $50K to burn and get a TT right off the bat I would but I don't. Besides, this will make a good project for my son and I when he is a little older and ready.

POST 19Original post

My $0.02 is that if you're looking to emulate a GT2, it might be less trouble to start with a 996TT and convert it to RWD and add the GT2 bits and pieces. Or take a 996 and supercharge or turbocharge it. Dropping a TT engine into 996 chassis not designed for it seems like a difficult proposition.

POST 20Original post

IMHO, you are in sunny CA, why do you need AWD? It just makes the car slightly slower, without reaping the rewards of driving in the snow (like the Coochas video of the C4 sliding around the N'bg Ring)!

POST 21Original post

It's actually a C2 on the Ring in the snow. Snow tires and driving skills are much more effective than AWD on winter roads. http://coochas.com/porsche/Resources...eifewinter.wmv

+1 If I had to go for a drive in the snow and I had the following two cars sitting in my garage. - 996 C4 w/summer or all season tires - 996 C2 w/snow tires I'd grab the keys to the C2. Snow tires are that important in the snow IMHO. (FWIW obviously a C4 with snow tires would be the "best" choice for driving in the snow)

POST 23Original post

The c4 feels more planted in front at speed. However, traction control and the awd make driving fast too easy, it's not scary. My latest has 2wd and no traction, the way I like it. Now, I scare myself all the time....... Stock c2's feel light in front imo, however, the aero is very planted and similar to c4 in feeling at high speed in straight but still feels responsive and nimble plus scary........ he he.
