Re-imagined Porsche 911 (992)

It's been a little over two years since I bought my current Porsche 911 (992) Carrera Cabrio.

Mainly for everyday use, but also for driving schools andcircuitI've also been running andgrand touringThe mileage exceeded 13,000 km while going to OnlyI drive about 6,000 miles a year, so for me, I don't really understand the 992 yet.I think.

Such is the 992, but it is time for a change of image.

When this car was originally ordered, the wheels dared to be the stock 19/20 inch Carrera wheels. The reasons for this were.

1) Expectations for ride comfort due to light weight, an advantage of small-diameter wheels
(2) Since the wheels can be replaced later or at any time
(3) Balanced with smaller brake discs compared to S

It was for three reasons.

Regarding (1), I have since found that there is not much difference in ride quality between 19/20" and 20/21" in various 992s. And for (3), I came to think that the basic Carrera does not have red calipers, so I don't feel that much scuffiness even with 20/21".

Therefore, theWhy I decided to try to change the image of (2)The first is.

Why did you choose Satin Aurum wheels?

When we decided to replace the wheels, we first considered the Carrera Classic wheels, which we love. I was initially considering Carrera Classic wheels, which I love, because they are comfortable to ride on and have a very elegant design.

But if you're going to replace them anyway, I'd rather have the same silver-based Carrera Classic wheels you have now than theCandidate for Carrera S wheels in the factory satin aurum paint, a color that looks great against the body color aventurine green.The first is the "I" in "I".

Originally.When ordering, I considered several times to get these satin aurum painted wheels.I also remembered that my wife, when she was configuring her own ideal Carrera, chose a Gars Red body with Satin Aurum wheels, and she said that she very much liked these gold wheels.

Besides, I've seen it before.Tested 718 Cayman GTS 4.0but I had a memory of the same Aventura Green with Satin Aurum wheels, which were very cool to see in person.

It just so happened that I was able to get a used, genuine Carrera S wheel with Satin Aurum paint. They were in reasonably good condition and had the factory air pressure sensors (TPMS) already installed, so I decided immediately to buy them.

When actually installed

Appearance

A few days later, the new wheels arrived.Nishinomiya BaseThe shoes will be changed at the three

After installation, the image is quite different from before. It has a very mature atmosphere, but with just the right amount of flair, and I feel that people are more likely to look at me when waiting at traffic lights.

Since aventurine green is originally a mineral color, the gold color of satin aurum fits very well as the same mineral color. Plus, in the case of my specimen.Since the interior is moher beige, it is not strange to see the same color on the wheels as the yellow elements of the interior.

In fact, when I saw my car parked in the parking lot, I got the impression that the car was very "flowery" and even gave the impression that it was some kind of test drive or demo car.

Impression of ride quality

Now, as for the impression of ride comfort, which is of interest, the conclusion is that at low speeds in the city, the 20/21" is clearly more comfortable to ride in. To elaborate a bit more.The impression of about 10% less shaking on rough terrain and more moistnessThe first is.

I've often wondered about this with PCCBed individuals and without.Light under-spring gives the impression of bouncing at slightly lower speedsIn some cases, the heavier the spring, the more comfortable the ride is. On the other hand, the heavier under-springs often give a more comfortable ride. In the same way, the suspension seemed to be more relaxed from the moment we started driving around town after the replacement.

On a side note, when I mentioned this on Twitter, I received valuable information from a former vehicle kinematics engineer at a car manufacturer that wheel stiffness is important for ride comfort.

I have made and evaluated wheels of the same size that were shaken for mass and stiffness. Stiffness is easier to experience than mass. If it is light but not stiff, it is no good, and if it is heavy but stiff, it rides and steers well. So I don't trust lightweight aftermarket wheels.

When we took the car to a mountain road for testing, we got the impression that the 19/20-inch wheels were a little more nimble, as expected. In particular, I feel a slight difference in response and agility when stepping on the accelerator pedal. However, it is not noticeable without direct comparison or being told, and I already feel no sense of discrepancy.

Handling and cornering characteristics are basically the same. The difference here seems to be more due to tire brand than wheel size.

My impression on the highway is thatSo far 19/20" feels more comfortable to ride.With 19/20-inch wheels, the faster you go, the flatter they feel and the more the unevenness of the road surface disappears, giving the sensation that you are driving on a smooth surface, but with 20/21-inch wheels, you do not feel this sensation as much.

However, this seems to be mostly influenced by the brand of tires.

The 19/20-inch was equipped with Pirelli PZERO (Porsche-approved NA0), but the 20/21-inch is Goodyear's EAGLE F1 ASYMMETRIC 3 (Porsche-approved NA0).

Goodyear's EAGLE F1 was once installed on my new 981 Boxster GTS, and my impression of it was not so good. The grip on wet roads was excellent, even better than Michelin, I thought. However, there were a lot of micro and non-periodic vibrations, such as knocks and pulls at high speeds, and I immediately asked the dealer if I could use the EAGLE F1.Is there something wrong with the wheel balance?I was even asked to look at it as "the best of the best.

After all.Then I switched to Michelin Pilot Sport 4S, which dramatically improved the ride and made it glide on the highway!Remember.

This can be found on the blogtouring journalPlease refer to the following information, which is also written in the following section.

This time, I had exactly the same impression, and compared to Michelin's Pilot Sport 4S and Pirelli's PZERO, they are clearly different. This is almost certain because my friend who experienced all three types of Pirelli, Michelin, and Goodyear at 992 also said the same thing.

So we plan to replace them with Michelin at some point.

Changing wheels gives a very different impression.

If you're a watch lover, you'll know what I mean.It's just like changing the band of a watch and the impression changes at once.It's a good idea to change them once in a while for an image change. Many Porsche options cannot be retrofitted, but since wheels can be easily changed, it would be a good idea to change them once in a while for an image change.
