Someone already posted it right above you. The whole center lock design for street cars. Pure marketing and now they are paying for it with a very expensive recall. I don't think 20's should be standard thats all, just to big IMO. Very little tire choices if you track as well. I've seen the cost of GTR slicks and its out of this world.

 

As long as it doesn't compromise handling, it's fine to me.
Everytime I read about 20' wheels, I always think about quality of roads in my country, which is obviously a mistake. I believe that US has way better roads, so the difference in handling will be hard to notice. In my country, driving in 19' is really a challenge, whereas in USA people seem to have no problems with it.
And as far as the looks are concerned - 20 inch wheels will look great, it's not like 26 or 28 (no offence rappers ).

 

I declined on my response. I have no background with anything above a 15 inch tire. Never driven a "sports car" beyond a Nissan 240Z, sorry to intrude on all your knowledge of tires. My mistake. Wow, you actually take your car to the track? So are you fast?

 

I feel it handles the same when I had the fac 19 inch wheels on it.

 

Let's be honest, if you're really concerned with weight (not just having expensive Porsche wheels to brag to other 911 owners about) then you'll be looking at all the aftermarket companies - Volk, BBS, etc.


I don't think the centerlocks were such a bad idea, though. Nor are the all marketing. For cars that might actually be tracked, it's a nice feature.
The Ferrari F40 had them in the 80s with no problem, so it's not too new of a technology to make reliable in a street car. The CGT had them with what seems to be no problems. Countless other exotics use them every day without any failures. Seems unusual for Porsche to have such a hard time building something that others have already made reliable.

 

I think they will look great, I also think that in many parts of America the ride will not suffer. In NYC though it will be a different story.

I'm fine with them either way, if anything I'm sad that if I were to get a 991, I couldn't get it with the 20's because of where I live.

As a whole I'm disappointed the 911's are getting bigger and heavier, but that's a topic for another thread.

 

And if you're really, really concerned about the weight of your Porsche, you could always just go on a diet.

 

You're oversimplifying the situation without all the facts. Read what people who actually track their cars think about the centerlocks:

I doubt the new 20" wheel will be standard on anything. I'll bet they are just adding another wheel option to the mix.

 

Those are all specific to the 911. I made the comment that other companies have used this before without nearly as many issues.


For many people, that wouldn't be a bad idea.
