Let Audi S7 explode with infinite possibilities, APR STAGE2 plus PS4S usage report

Hello fellow car friends of Zhijia, this time I would like to share my experience with my car and the things I have replaced it with! Looking at the title, everyone thought it was RS7. In fact, this is an S7 with a modified RS7 appearance. I really can’t find the S7 forum, so I can only share it through my brother’s A7 forum. I have been working on the program for so long, the tires have been used for half a year, and the car has been driven for so long. I have long wanted to write something. After half a year of holding back, I finally figured out what the focus of the article is. There are three highlights of the car. The first is the grille of RS, the second is the second-level program, and the third is the tires of PS4S. After my research on the forum, I feel that everyone is concerned about the latter two. I’m even more interested, so today I’m going to talk to you about the infinite possibilities that come with second-level programs and PS4S. ?PS: The picture quality is too high, high energy ahead!

Let me introduce it first. My S7 is equipped with the second-level APR second-level. After picking up the car and running it in for a week, I drove it directly to the modification shop to have the ECU program implanted. I chose the APR? STAGE? Level 2 program because it uses the OBD port for flashing. The advantage of this method is that there is no need to disassemble the original ECU, which avoids warranty issues in the 4S store after opening the board. The price of the APR program is relatively high, but I personally think that the APR program is the fastest and most stable among canned programs, and the after-sales service is very good. You can switch and flash between the original factory and first- and second-level programs at will, and no restoration fee is charged. Even if there is a problem, the warranty will not be affected.

Here are some photos of the car first. I drove to the roadside under the blue sky and white clouds and took some photos. I also called my friends who were playing with the car (same color). After all, it is too much to be alone. Alone.

As for tire selection, I have done a lot of research. I considered Pzero but I heard from friends that I was not very satisfied, so I changed my target to Michelin. Michelin’s PS4S can be said to be the best among performance tires. As for performance tires, I read a very professional review of PS4S, P0 and other performance tires the other day. The advantages of PS4S are too obvious. This s7 is too suitable for this tire. No, it should be that this tire is too suitable for s7. .

There are still photos of the tire selection at that time, please take a look. Because I made an appointment on the official website, the guy who came to the Chijia store to help me replace it was very nice and brought me the tires. I saw that they were good. Friends are using it and the actual product is exactly as described by netizens. After seeing the real thing, I paid the money and let the master install it directly. ?The asymmetric "little lightning" patterns inside and outside can increase the vehicle's lateral grip and improve its cornering ability. This is why the PS4S's cornering performance is better than that of the same car if it is equipped with different performance tires. There are many levels.

Large-sized wheels look big. The behemoth appears in front of you, and it is about to bid farewell to old tires and embark on a new path of performance cars. The plush imitation velvet design is really comfortable. The eye-catching Michelin logo and imitation velvet design look very high-quality. I have never seen such an interesting and iconic design on other tires. It is indeed a tire. The "King of Beauty" in the world!

The pattern of "Little Lightning" feels very unique. The reason why it is called "Little Lightning" is because the patterns are very similar to Little Lightning. I asked the master and he said that the tires of the PS Racing series all have the same pattern. "Little Lightning" is a proprietary pattern of Mercedes-Benz, which can be regarded as a very iconic design.

In fact, you can feel the change after replacing it. I specially washed the wheels and body in order to take pictures. After all, after half a year of use, there will still be some dust.

About the feelings? At present, I feel that the PS4S tires are very good in all aspects and have no shortcomings. It can be said to be a perfect match for the S7, and even for all Audi performance cars. I have seen it before There are many cases where RS3, S3, RS4\5 have been replaced with PS4S, and the driving response has been very good, whether for street riding or transportation. Owners of modification shops in the circle of friends are posting every day that someone has replaced their car with PS4S, and sure enough, Car enthusiasts are willing to replace their cars with good tires. ?PS4S finds a balance between sportiness and economy, and does not sacrifice comfort for road grip like those semi-thermal tires. PS4S supports medium and large wheels, so it is suitable for most cars. Drivers who are ready to change tires are strongly recommended to try PS4S.

Michelin tires are stable and the steering wheel does not feel shake at all when starting to run (I was also worried that the new tires would shake). The control is greatly improved. It was also very worry-free when doing dynamic balancing. I just used it. A very small amount of lead was used, and the master told me that the tires made with Michelin's multi-valve technology are more regular and uniform, and they drive very stably.

I really like the tires now. The previous wheels are already a thing of the past. Audi wheels are more suitable for Audi cars. The other styles seem a bit inconsistent.

Having been running for half a year after changing the tires, I recall that compared with the previous tires, the overall effect is very outstanding, especially the grip on wet roads. There is no slippage in either dynamic acceleration or static acceleration. I started on the same road section. It started to slip when I stepped on it halfway, but now most of it is fine. It can be said that it is very good, let alone the grip on dry roads.

About tire noise, some people will ask whether the tire noise will become louder if the road grip is so good? On the contrary, the tire noise has been reduced, but my feeling in urban areas and on the highway is that it is obviously lower than before. a lot of.

?Although the large wheel aspect ratio and tire performance are not so outstanding in terms of comfort, don’t forget to choose Michelin tires with some reservations about comfort. With the S7 model, there is still a little reservation about comfort. , but with the PS4S, the only thing we care about is the controllability and the grip on wet and dry terrain. It is really a qualitative improvement. It feels more secure even when traveling on high speeds.

Sometimes when I go back to my hometown and walk on bad roads, I will take off the PS4S (I feel bad about the bad roads). This is the one time I took it apart after traveling more than 1,000 kilometers and took a picture. There are no scratches at all. The material used is Michelin. It’s really true. Of course it has something to do with the technical aspect. Michelin has accumulated a lot of tire technology in international events such as F1, F4, and Le Mans over the years. Applying track technology to civilian tires is a kind of technology sinking. Bar.

The big fastback shape is so beautiful. I have never seen a car with a more beautiful fastback shape than the A7 series, not even the Panamera.

Anyway, now that China Open, Tier 2, and tires are all equipped, I really can’t let go of my car. I will work harder this year and get a real RS7 next year.

The last two beautiful pictures are for everyone. If you want to use them as wallpapers, I will send you a message privately~

I am really not professional at writing articles, but I am still very serious about taking pictures and play professionally. I have been taking photos for many years. I only got into car photography in the last two or three years because I like cars. I beg the moderator to improve it! grateful!
