You could get a MY02 narrow body C4 in the U.S. ( Don Cape Cod has one ).

The C4S didn't get to N.A. until Feb. of 2003.

My bad, but that still doesn't answer my question to the OP. If he has a US '03 it can't be a C4, unless it is a ROW car.

I think you're taking Porsche's statements that the GT3 and cup cars are based on the C4 tub a bit too literally. they basically used the upgraded bracing for chassis stiffness within the tub itself but nothing really changed dimension wise for anything else. The GT3 control arms will bolt up to any model 996, boxter and even Cayman. The advantage to these arms is that they're 2 piece vs. 1 in the standard cars. In adding shims between the two pieces of the control arm you can easily adjust more negative camber into the suspension which all of our cars are lacking. Personaly I feel the lack of negative camber in the front is part of how Porsche builds understeer into these cars to rid them of the notorious handling traits of the earlier 911's.

Thanks
Though my english isn't very advanced, I understand perfectly.

I have a model that is unique to the USA but I do not think so.

I have a 2003 C4 Cab. More wood inside that can be used to keep a fire alive in winter.

I believe I have seen several of you or at least one witha 03 C4 Cab as well.

I wish it was a coupe, but since wife wante a Cab and if "she is happy, I am happy" the a cab it is.

C4 Cabriolet narrowbody was in the US market
Not so rare

C4 narrowbody Coupe wasn't in the US market as Ray said since 2001

Mine from what I can see is a Wide Body 03 C4 Cab. Based on what I saw side by side. Maybe I am a lucky one

Ray S

If it's a wide body, it's a C4S unless someone performed a conversion.

What color are your brakes? What are the size and offsets of your rear wheels (and are they stock)?

Ray, here is the car:

Carrera 4 narrow body

Not true. I have one of the first C4S coupes. It is a MY 2002, delivered and bought brand new in Feb 2002 in Canton, Ohio. Had to bring it back to the dealership the next Saturday, since it was a "launch car" for them and they wanted it in the show room. I conceded it for that Sat, with the strict rule that the doors stay locked.

Starting with MY 2002, there were no C4 coupes, they were all C4S coupes. There were still C4 cabs. The C4S cabs did not show up until 2005, I believe.

Anyway, back to your original question.

The X74 is quite stiff. Among the Porsche-made options, it is the lowest and stiffest. I have the equivalent, the X73, on my C4S. I have one road to work that has bad-bad-bad expansion joints. X73 makes the drive irksome. But then I go to the track. X73 makes the drive oh-so-wonderful. If your car is going to be a frequent or daily driver, and if you have bad roads, and if you don't track frequently, go with the 030.

I would sware the one that I parked next looked narrower than mine. Maybe are the wheels and the offset.

I Florida, I have not come across any bad roads to speak, and since this is a "fun" car not a daily (may become due to addiction)< I am not worry about stiffness.

I will not tell the wife that I made some "minor" changes.

Thanks to all

PS: has anyone change the front bumper to that of the C4S. I like that look better. (I wonder if she will notice)

There are hugh differences between C4 narrow body and C4S (wide body).
6 cm wider: 1,83 m vs 1,77 m
rear fenders, front and rear bumpers, rear red strip, and a few more...


There is no problem to upgrade C4S front bumper in your C4. 996 40 th gets it as stock factory.

To further the OP's original question, does any know how the spring/shock rates compare between the GT3, ROW, and X74 compare? I've seen the PCA article which lists the stock and ROW settings, but nothing on the GT3 and X74.

Rob in WA

I meant Feb. 2002 and yes the vast majority were cabs. I could've sworn I've seen sales figures for MY02 and a few C4 coupes were brought to N.A.; of course I can't find it now.

AudiOn19s

Stock rates (linear I believe) 146 F / 203 R
M030 rates (ROW AND US) 170 F / 260 R
H&R Springs (progressive) 170-210 F / 230-260 R
GT3: 228 F (linear) / 543 (progressive)

you won't find X73/X74 rates. I tried for along time and could never came up with rates. I've riden in one and the feel felt very similar to a GT3...which in my opinion has too agressive of valving in the shocks and not enough spring rate.
