I'm looking at adding spacers to my 2014 991.1 C2S. The fitment should be the same as the 991.2 NB? I'm looking at the ECS 8mm front and 15mm rear. Any photos or input is appreciated. I have Carrera S wheels with stock 245 and 295 width tires.

Did you end up doing the 8/15 set up on your 991 C2S?
Considering the same setup and looking for feedback.
Do wheels look flush with fenders?
Any vibration or change in performance?
Any regrets (would you do the same sizes over again)?
I ordered 8 F and 12 R but haven’t installed them yet. I’ll get a chance to install them this weekend. I specifically ordered the ECS spacers because they are hub centric. I’ve used spacers on other cars and I’m not expecting issues with vibration.
...The fitment should be the same as the 991.2 NB? ...
The wheel fitment for the rears is quite a bit different between the 991.1 and 991.2, so numbers for one will not work for the other.
For example, comparing 11.5" rear wheels available for each model: on a 991.1 NB the offset is 68 and looks fairly inset, while for the 991.2 NB they have a 76 offset but appear almost flush in the wheel well.
Usually a larger offset like that seen on the 991.2 wheel would make the wheel look more inset, so it seems clear that the hub mounting points on 991.2 models are placed much further out than on 991.1 models (with them having both a larger offset yet an almost flush appearance).
I had ECS spacers on mine 5mm front and 12mm back without issue. Some rubbing at full lock up front. OEM setup on my 991.1. Very flush tho. Removed with new aftermarket wheel setup as wheels are just a flush I think without spacers installed. Here is the car with ECS spacers installed though.
5mm installed
5mm installed up front.
12mm rear spacers installed

Car came OEM with 5MM all the way around. I went with 8/10. It's still not flush but it's better.
right, but your car is lowered so that affects the effect of spacers. See what I did there? Jk. Usually a wider spacer is necessary on lowered cars to achieve similar results on a non-lowered car.

This is true but i'm not really any lower than a SPASM car so anyone reading should perhaps take that into consideration. With a proper alignment, it should make less difference; I'm not a fitment expert but think you're right. Also, Porsche OEM wheels have slightly different offsets too.
I ran 15mm all around and 7mm front 15mm setups. At the end, I took the spacers off since I didn't like the handling characteristics. It also affects scrub radius and effective spring rate in a bad way.

I need to inspect this. Haven't noticed any change as you describe.

I’m running 15mm front and 7mm rear spacers with extended bolts (will swap to studs in the future) on my 991.2 narrow body 911T. Factory 20x8.5 and 20x11.5 S wheels. I did this to widen the front track mostly to get added grip and reduce front end push when on track. I love the enhanced grip on track. The look and stance are also much better. In my opinion the front wheels always seemed tucked in too much from the factory and now I have 30mm more width up front. No downside for me other than a little more debris being thrown up on the fenders but I have PPF.
