Here's the weight numbers that you should be familiar with before you jump onto other wheels. Weight, particularly unstrung weight, is a handling killer. You never stated the objective of this move to these wheels. By using the non-standard term "sick" I am assuming you are in a particular age group that may value the 20 inch look over the 19 inch wheel.

997's aren't purpose built race cars. The car wasn't intended to be a pure track car. About half of the things in a 997 detract from it's performance like AC, sunroof, carpet, stereo... the list goes on. He isn't putting 20" rims on a cup car. By your rational everyone here is a poseur. All of you weekend Wolf Henzlers need to get over yourselves.

I'd can't imagine bending a wheel and needing a replacement. What would your friend charge to set up and make 1 replacement wheel. I'd take a pass even if I did want 20" wheels.
I can't imagine what durability testing was done to validate the strength of these wheels.

Replacement time is simply the CNC machine time. With the files there is nothing special about sticking a piece of billet aluminum in there and letting it start hogging it out.

So I guess the time for quoting material, ordering material, receiving and inspecting material, scheduling the job to run, setting up a CNC lathe with tooling and program, inspecting, setting up a CNC mill with tooling and program, inspecting, finishing/plating/painting, etc. is all done for free? This is way more involved than pushing a button. Heaven forbid an endmill breaks during machining and scraps the wheel on the last step of the job.

Would someone care to explain why 20" works for the GT and not 997? And, is the take-away here that 18" wheels actually work better for 997.2 than the stock 19"? If that's the case, I'm running out and swapping my wheels -- as is, I'm swerving all over the place to avoid NYC potholes, which a-hem, are bigger than ones from the 2nd city any time of the day ![Wink](https://rennlist.com/forums/images/smilies/wink.gif)
Swerving in PCar, btw, is kinda fun in itself, actually....

about this very subject. Remember, poseurs are more concerned about how their car looks and not about how they drive.

I stand by what I said in post #4. The OP asked for an opinion and I gave it.

Hey guys, much appreciate the feedback. The "poser" comment seems off, cause I am not trying to turn the car into a different model. If I put a GT3 wing, wheels, etc. then that is a poser in my mind. Somebody asked age group, I will be 40 in March, everybody I know in the metro area that is my age refers to things as "sick" if something looks cool or awesome, unless they are terds. If they truly will mess w/ the shock dynamics and compromise handling, I will be thinking twice now. The overall circumference of the setup is the same, given the lower profile, but I will get the weights on them for the rotating mass factor. The wheels are one piece. As far as off-sets go, I will double check, but he made these wheels specifically for a 997, so I trust they are correct, given his expertise. I only took pics of the rears, the fronts do not have such a deep dish. Pothole wise is not an issue, I do not live in one of the Boroughs, I do have an apt in the city, but split my P_car time between my houses in Northern Westchester and the Hamptons, so the roads are up there in quality. The car is not my dd, it is one of 4. My dd is a 10' E550 4Matic, that handles the city.

I spent most of this thread trying to figure out what a "pouser" is.
Mauser
Bowser
Yowzer
Doogie Pouser
I don't want to be a hoseur by posting this. (Eh?) I didn't realize 20" wheels would have such an effect on performance, but then, that's why I read these posts.

The original poster asked what the forum members thought of the wheels. Many members rendered an opinion (some with gusto and conviction). None attacked the original poster. In light of that, do you think your responses above are necessary or appropriate?
It appears you are new here. No need to blow the door off the hinges with grenades in your attempt to come in and play, yes?

Being new doesn't make my opinion any less valid.

Your equation left out a very important performance feature, handling. The greatest asset the 911 has is in the handling, anyone contemplating to change this characteristic will usually opt to improve it not muck it up. In addition, I venture to say that a good number of Rennlisters regularly track their cars and thus know more

Are those your cars in your profile picture? Cabriolet and Cayenne?
