Does modifying the ET value of the wheel hub so that the wheels are flush with the fenders affect th

When it comes to improving the driving performance of the vehicle, there are several major projects: power and transmission system upgrades, frame and chassis upgrades, electronic assistance system upgrades, etc., and there is a lot of knowledge about frame and chassis upgrades, and it can directly improve the extreme performance of handling, which has an immediate effect in many daily use environments. The so-called improvement of handling performance, the conventional methods are nothing more than a few:

Replace the suspension package with more support and better mechanical properties, change the rim combination with lighter tires so that the suspension response is not dragged down by inertia, and change the tires with better grip to make the directivity more obedient. And so on, these effects are definitely what car owners like to see, but they all have a common feature, that is, it is more expensive, and ordinary car owners may not be able to afford it. Is there a cheaper and more cost-effective way to improve handling performance?

But is there not some "cost-effective" and safe solution other than these methods? Here's a different approach: rim flanges and gaskets.

Its principle is extremely simple, that is, the joint surface of the wheel hub and the brake disc brake drum (also known as "fitting head", "hub head") is cushioned with a certain thickness of metal gasket or flange, so that the relative installation position of the wheel hub extends outward, in simple terms, the wheel base is widened. A certain degree of widening of the wheel base will make the driving dynamics of the vehicle on straights and curves more robust in terms of geometric angles and vehicle driving characteristics.

Don't underestimate this modification method, for many ordinary owners who don't want to make a big move, or can't find the right rim to enhance the "fullness" of the car friends, it is the most simple and direct way, and, in foreign countries, especially in Europe, there are people who use the "suspension foundation upgrade three-piece set" habit, such a modification has long been popular, the so-called basic upgrade three-piece set is: sports springs, anti-roll bars, gaskets, sports springs to increase support, anti-roll bars to inhibit cornering rolling, Rim gaskets improve high-speed stability. Still can't accept the modification upgrade?

It's just a matter of perception.

Although the modification of flange gaskets and the replacement of suspension can not be compared with the comprehensive reactivity improvement, the improvement brought by it can be directly felt in daily operation. In the group of car players, the rim matching will often use a common concept of "Qi sand board" in the industry, which means: from the top of the fender vertical outward, the plane of the wheel rim and the outer edge of the sand board fender are close to the level, do not think it is simple, the rim edge exceeds the outermost edge of the fender is illegal.

At the same time, in addition to the appearance of fuller and more fit, the benefits of flush also have effects such as reducing the airflow vortex on both sides and increasing the wheel base, while the addition of flange gaskets can achieve this effect without replacing the original rim; Not replacing the rim, but also reduce the concerns of some owners about the annual inspection-related problems, the wheel hub cushion out, can also be said to be a disguised increase in the ET value, leaving more room for upgrading the brake caliper. Precisely, this also represents another original optimized modification style.

It will not affect the handling, as long as the normal modification procedure is followed.

It will have a certain impact, after all, it has been changed.

It won't affect you. There are just a few deviations.

Of course, it will also affect your driving feeling.

I don't think the overall impact is huge, as long as you control it properly.

Yes, it will have an impact, and the impact is quite large.

The ET value represents the value of the center offset of the hub, which represents the deviation distance from the center line of the rim to the fixed surface of the hub. Therefore, the more negative the ET value, the more the rim will be mounted on the car.

More or less had some impact, after all, it was modified.

ET refers to the rim offset value.

This value is the value from the center of the rim cross-section to the fixed datum of the screw hole, which is positive for the average tourhome and negative for a few vehicles and some jeeps. For example, if a car has an ET40 offset value, if it is replaced with an ET45 aluminum rim, it will be more retracted into the wheel arches than the original iron rim.

This design is related to the steering characteristics of the vehicle and the angle of wheel alignment. The original factory setting value is usually optimized design, and the offset value that is too large may lead to abnormal tire wear, easy bearing wear, and even loss of control during high-speed puncture.
