I'm thinking about going from OEM (205/50/17 and 255/45/17) to aftermarket wheels with 235/35/19 and 295/30/19, but other than looks, what's the trade-off?
Diameter if fine, but front width is 1"+, and rear width is 1.6".
Will ride be noticeably harder? Does offset need to change (to what?)? Can the swap be made without changing suspension or lowering? What am I missing?
Like he said. The 19s ride terrible on my car. Stick with 18s but your tire widths are fine. My rims are gt3 spec offsets and thats what u want. Also if u have an mk1 u may have to roll the fender. Suspension height and alignment if different from stock may also effect fitment.

If we were closer - I'd be willing to work a deal for your 17" wheels for my 18s.
Agree with the comments regarding 19s. That's a big NO, in my world.
18"×9" and 18"×11" are about as big as you are going to want to go on 996.2, imo.
Yes, the ride is going to change
The picture you are looking at is 18"×11" w/ 295 30s on the rear.
I am curious if any one has gone to a 35 rear tire?

What ET are your wheels? I'm actually looking at a set of those same sized wheels, 18x9 et 43 and 18x11 et 63. Wondering how the fronts fit and size of the tires. Thanks.
I like yours too. They wouldn't last long on the third-world roads I have to drive on.
They aren't too bad on New England roads, which also are pretty terrible. They are certainly harsher than 18s, but not terrible. WAY lighter than the stock twists, so I'm sure that helps.
You guys hating are hilarious. I have OEM 19's and they are great. Never had an issue. Just get the right tire sizes (Hint 996 are different vs 997). Most people who have problems are running the wrong tire sizes.
I swapped out my suspension with new springs/shocks and 19" tires/wheels at the same time and the ride was remarkably smoother after doing so. If you want 19's get a lightweight set that is OEM or forged quality with the correct stagger/tire sizes and offsets. You won't have any issues.
I have a set of 18 Twist, and a set of 19 Fuchs replicas. I actually enjoy the 19s more in the twisties than the 18s. Long Road trips are where big sidewall's shine imo. This has been the way with all of my sports cars with stiffer suspension.

Yes - mass and tire volume* are both important factors.
* You have to go to a lower profile tire when the wheel diameter increases. If width increases, which it usually does, actual tire volume may remain similar. I did a lot of durability testing on vehicles with performance wheel/ tire packages. My experience supports the "volume" theory.
What doesn't work for me, is pothole and other sharp (square wave) impacts. Low profile tires don't play well in that environment.

I don't think anyone is "hating". There are aesthetics and functional considerations at play here. I lean toward function. Many lean toward aesthetics. That does not constitute hatred.

The weight saving was a big plus. The difference was instantly felt. The car is way more responsive now. I agree, pot holes aren’t great for low pro tires. They are 235/35 and 295/30s, so not too crazy. Standard size for a 997.
I looked up wheel weights and came up with these numbers.
Stock Turbo Look Wheels
Front 18x8: 26 lb 4 oz
Rear 18x10: 31 lb 15 oz
Lobster
Front 19x8: 22 lb 4 oz
Rear 19x11: 27 lb 12 oz
Savings of approximately 16 pounds of rotating mass.

Thinking about OEM to bigger wheels....
