So how much wider is it? Would love to see side by side rear shots. Any pics??

 

991 C2 is 71.2 in. and 991 C4 is 72.91 in. basically the same as the 997 widths.
I am surprised as I thought the 991 WB was going to be wider than 997 WB from reports I had heard. I think the increased wheelbase and marginal longer and lower body give the 991 a wider appearance. I find the 991 looks a lot different than the 997 in photos, but in person not as drastic.

 

The question is will the new 991 GT3 have the C4's rear body and track/width (like the 997 GT3RS did) or have the C2's rear width (like the 997 GT3 did)...

 

I thought the 991 c2 was as wide as the 997 c4?

 

I also thought the C2 had the width of the 997C4??

 

Yes I thought so too...
