On the track, Mercedes-Benz AMG C63 upgraded the ray G 16 MK Michelin PS4S!
Urban building map
From the initial contact with C63 to getting familiar with it, and now mastering it skillfully, I have found too much fun from C63. Every time I take my son out, the moment of ignition is his most exciting time, and the rich exhaust rumbling. Every time I see him excited, I am very happy.
With more and more riders I know and more friends who play with cars around me, I decided to give it more possibilities to go to the track!
The first step in track preparation is to replace the hub tires. Is the wheel hub selected by ray? G 16? MK? 19 inch wheel hub, and the tires are Michelin-made hua dan PS4S high performance tires.
Let's start with Michelin ps4 high-performance tires, Audi RS, BMW M, and AMG, an old customer of Porsche. I believe many friends who play with cars are no strangers. PS4S is absolutely unique in this class, even Pirelli's P0 is hard to match. The advantage of PS4S is that 80% of the streets and 20% of the track, so I don't have to use street tires and track tires respectively. The double tread formula of PS4S, the compound elastomer formula of the outer tread can strengthen the dry tire performance, and the functional elastomer formula of the inner tread can help improve the wet grip and braking performance, because no one can know the weather when running the track.
Let's talk about rays again. Many people think that widening tires with big wheels will improve performance, which is absolutely wrong. The size of tire and hub directly affects the rotational momentum and linear motion momentum, which is also the reason of inertia as the saying goes. If inertia increases, it will affect acceleration and braking. If we want to improve performance and widen tires, we should use lightweight wheels. Inertia is the property that an object remains at rest or in motion. The greater the inertia, the more difficult it is to change the state. Tire inertia mainly has two kinds of inertia: 1, and wheel inertia moment: tire inertia moment directly affects acceleration performance. Because when accelerating, the greater the inertia of the tire, the slower the increase of tire revolution and the slower the acceleration of the car. 2. Inertia of wheels moving up and down: Because the road surface is not 100% flat, if the road surface fluctuates up and down during high-speed driving, the tires will move up along the suspension direction and then bounce back to the road surface. If the inertia of the tire increases, the time to bounce back to the road will increase, which will lead to the increase of the suspension time of the tire in the air, the discontinuity of power output, or the increase of the probability of slipping.
The influence of the shape of the object on the moment of inertia can be brought to the hub. Forget the tires. The shape of the hub itself will also affect the moment of inertia of the wheel. If two wheels of the same size and weight are different in shape, the moment of inertia will be different. Ray? G 16? The rotation of MK is small, because the mass supported by the hub is mostly concentrated in the center, while the heavier part of the tomahawk hub is close to the outer edge. Ray? G 16? The design of MK will increase the moment of inertia, and the performance will be stronger. Therefore, when selecting the hub, we should not only look at the total mass of the hub, but also look at where the mass is distributed. Remember, the farther the mass is from the center, the worse the situation is.
Master's care is beyond my imagination.
The two masters went into battle together. Have you ever seen such a big battle of changing tires? Ha ha laugh
It's done.
Looking at the effect of the foot, the distance from the tread to the wheel eyebrow is about three fingers. The suede design on the sidewall looks advanced, and the logo of the track flag is scary! ! My tire size is not available in full sidewall suede version, PS4 and PS4? The SUV is full-tire suede design, and the whole circle is this 94-degree dark suede design. If you have a chance, you must try. Very handsome.
Is it like replacing C200 with C63?
Send some fine-tuned pictures.
The shape of C63 is too low-key. Look at the new M3 and M4. I wonder when Mercedes-Benz will make it impossible for ordinary C200 to be converted into C63.
Since I changed my tire in September, I can say something important.
Let's talk about the feeling of daily driving: the first feeling is comfort. For the first time, I feel that the ultimate handling and comfort can be owned by the same tire. Michelin has always been known for its quietness and comfort, and high-performance racing products are no exception. The performance of ps4 is especially in place. The noise of tires driving at 60km/h on urban roads is very small, and with the sound insulation and streamlined design of C63, the noise transmitted to the car is very low, except for rumbling. When passing through the speed bump, the vibration filter is obvious, and you won't feel the extra bounce and bump in the car. In short, PS4S is a very suitable tire for daily use in sports cars and performance cars.
Let's talk about the feeling on the track. I have run the track three times since I changed the tire. What I look forward to most before changing the tire is its performance on the track. When all 476 horses were released, it was still very exciting in the senses. At the same time, if PS4S wants to control this performance monster, it has to rely on its super-intelligent tire pattern design to make the tire contact pressure and temperature distribution more uniform, and ensure the tire grip to maximize when the vehicle turns at the limit speed, thus improving the cornering stability. The improvement of lap speed is in the cornering details. When cornering, the tire is required to better transmit torque according to the driver's control instructions and provide stronger tracking, so that cornering can be more stable and faster. The tread of PS4S is a mixed material covering composed of lightweight high-strength aramid fiber and nylon. This material can make C63 turn more accurately, control more freely, and have a good braking effect when entering the corner. At the same time, it can also make the car turn out quickly without slipping and reduce the cornering time. By the way, the wear resistance of this tire is also quite strong. Three laps on the track, little wear!
Let's go back to the car and talk about shifting gears in the red line area. The backfire sound of exhaust is very nice. What impressed me most was the acceleration after the third gear. Although it is smaller than the 6.3-head displacement of the old M 156, the twin turbines of 4.0 are not small, and they are absolutely full of stamina.
