After searching and reading many posts, I am still confused. Any input would be appreciated. I have an '06 997S. I am currently running 235/35/19 and 295/30/19. I have the lobster forks 19/8.5 front and 19/11 rear. Stock offsets which I think are 57 and 67.
The wheels I am considering are the same size but offsets are 45 in front and 52 in back. Will they work and will there be handling changes. Car is strictly for the street.
Any input would be appreciated

Can't speak definitively on handling issues but the offsets, especially for the rear, were designed for the wide body cars (C4, etc.). Both the et45 and et52 will push the wheels out from stock by 12mm and 15mm, respectively.
The rears will be fine. You are going from ET67 to ET52. It's the same as adding a 15mm spacer in the rear of a NB car. Many do this already without issues. It's also very close to putting WB ET51 rear lobsters on a NB car. Many do this too without issues. No worries on the rears.
The front will be close though. You are going from ET57 to ET45. That's like adding a 12mm spacer up front. This is a bit more than most people do. Most use 7mm up front for a nice flush look. Yours would be poking out 5mm more. That's not a lot and won't have rubbing issues but it will be a hair outside the front fender.
If you move tires up to 305's in the rear, your front/rear "flushness" might look more balanced.
I will be putting the wheels on next week. Thanks to all who responded. I have also found some pictures of other owners who are using the wheels. They are the Ruger Mesh Matte Black 19" wheels.
I will post some pictures after the install.
I have the lobster forks 19/8.5 front and 19/11 rear.
FYI, the stock lobster forks in front are 19x8, not 8.5. So if you go up in width on the fronts too then that takes up more space as well as changing offset, but the Ruger Mesh wheels are a pretty common NB wheel that people use without issues.
I put 10mm spacers on my front lobsters one time and they looked great. I'm not sure why so many people only buy 7mm spacers for the front.
I just put Champion Motorsport 19x8's on front of my 05 S with a +46 offset and my car is lowered but I also have a more aggressive alignment with -1.4 camber up front so they sit well inside the fender lip.

As I understand it, it is not a handling issue so much as it is a bearing wear issue. As you change the offset, the load on the bearings change and becomes uneven. The systems are designed to place the load squarely over the bearings.. or at least allow for even load. When you go out of spec, you will incur accelerated wear and premature bearing failure. Personally, I would only stay within Porsche specs for spacers and offsets.... but then I care less about cosmetics and more on longevity as I tend to keep my cars a long long time.
That would be interesting to see if there is any increased suspension wear.
I do know that Porsche allows 5mm spacers. I read they have the stock wheels set up for the application of snow chairs per some European rule. So there is room to change offset somewhat.
