Difference between C4 and C4S
 

Hi,
I have a 2003 carrera 4 conv. and was wondering what the major difference is between the C4 and C4s. I think the difference is the front and rear bumper. My carrera doesnt have a S on the trunk lid. Im confussed because the dealers in Toronto, Canadasay its a C4 and when I look for parts in the U.S. they tell me its a C4s body. Is the C4S wider in the back end than the C4?
Sorry for all the questions, I appretiate any info.

I read on the Porsche site that, with the current model line, the C4 has a wider rear (compared to the C2) to accomodate a wider tire. I don't remember seeing that the S was wider still. Perhaps the US parts mongers are confused? I have a 02 C4 and it has wider tires than the 02 C2 and I'm pretty sure, a wider body as well.
