Each aluminum alloy wheel needs about 1,400 yuan
The car modification is the play of the car race, the dazzling appearance, the unique sound, and the improved performance all highlight the owner's personality.
Car modification is also divided into three levels: primary, intermediate, and advanced.
The conversion of the average rider is at the elementary level. They only do some upgrading of certain parts to improve performance. Shui Ge (net name) is the name of the owner of the Sinar. He usually loves to play the car. In order to better adapt to the racing field, he recently made some minor modifications to his car.
Tire width, hub diameter increase stability
The aluminum alloy wheels have good heat dissipation. The Senna tire has a width of 195 mm. The wheels are basically steel wheels. There is no problem in driving on the straight road. However, the racing car has high requirements for tire performance due to its high speed and sharp corners. , Water Brothers spent a total of more than 7,000 yuan selected Michelin 215/45R15 tires, but also equipped with the corresponding R15 alloy wheels. After the change, the tire has become wider, and at the same time, the flatness ratio has been further reduced. The grip of the tire has been further enhanced, and the increase in friction force has greatly improved the braking performance. During the road test, on the mountain road with pebbles at a speed of 120 km/h, there was almost no feeling of swinging and slipping.
Technician Tip: The role of wheels in driving stability should not be underestimated. The lightweight aluminum alloy hub can reduce the momentum during the driving process to a certain extent. At the same time, the aluminum alloy hub is generally produced by the entire mold processing. There is no solder joint, and therefore the safety is high. In the driving process, friction will occur. Produce a lot of heat, compared with other metals, aluminum has better heat dissipation, can quickly dissipate the thermal energy of the running process, maintain a uniform speed so that the body can maintain balance.
High-quality shock absorbers reduce roll
It is particularly important for high-speed driving, especially when crossing corners, to have good shock absorption performance. In the field races, the general curve has a 60-degree angle, and the speed of the vehicle is generally about 100 kilometers per hour, and the body is prone to tilt. accident. Fortunately, Saina's chassis is relatively stable, running on the general sand road, the whole body will not be too much shaking. Shui Ge only made modifications to the shock absorber. He spent 12,000 yuan in the auto parts base and replaced it with a KW-ZR shock absorber. After the modification, the effect is very obvious. When vehicles used to cross a right-angle bend at a speed of 120 kilometers per hour, they could obviously feel the body tilting towards the curve, and the ground clearance of the outer wheels reached 50-100 mm. After that, the two wheels traveled at the same speed. The spacing is only within 20 mm, and there is less side-slip during high-speed driving.
Technician Tip: Modification is not a trivial matter. Unreasonable modification is often prone to accidents. At the same time, modification is not “differentâ€. Reasonable modification can effectively improve performance. When refitting, it is necessary to combine actual needs and choose a regular Auto City. Spend money so that you can better enjoy driving a car.
