Many people say that it is safer to go to the racetrack to practice your skills than to race on the road, but in fact, you want to drive in the racetrack, but there are many concepts and work to be prepared in order to get off and on the race safely, and these preparation items What exactly are there? The author specially interviewed senior players who have teamed up to participate in the holiday walking meeting for many times, and shared relevant experiences, so that everyone can be a happy one-day racer.
With the official operation of Taichung Lihpao Circuit, all Taiwanese car owners who love racing Mercedes-Benz have a moderately distanced, convenient and relatively safe venue where they can fully exert their driving skills. However, compared to the street, although the closed-field racing track will not have sudden people and vehicles breaking into the lane line, which will affect the safety of the vehicle, but after all, the way of driving on the track is very intense. For people and vehicles , are different from the harsh test of the short sprint on the street, so before participating in the holiday walking meeting, you must be prepared for people and vehicles before you can safely go to the village.
What to do to prepare? Regarding these issues, the author interviewed Chen Yian, the head of APR Taiwan, and the head of Jieshi Motors, Wei Shengcheng, who have participated in the Dapeng Bay and Lihpao Circuit walking meetings for many times. Through their experience sharing, I will help everyone to quickly Get the point. According to the two car-changing experts, the preparatory work is mainly divided into two parts: the car and the person. Let’s talk about the vehicle first. Since the vehicle enters the racetrack, it often undergoes very intense driving, such as high speed and frequent shifting. , The brakes are very strong, the cornering speed is fast, the shock absorbers are violently acted, and the tires are rubbed and squeezed hard. These situations rarely occur when driving on ordinary streets. It is not as intense as the off-track, and the full-throttle time is also short on the track, so it is a big test for engine lubrication, heat dissipation, and heat exhaustion of shock absorber tires.
Therefore, they suggest that you must replace the relevant oil and water before going off the track, such as engine oil. If necessary, you can choose a fully synthetic oil with a higher viscosity index to add it. For example, 0W30 can be increased to 10W40 to ensure that the oil temperature rises When the temperature is very high, it can also provide enough protection. After all, the temperature of the driving oil on the track may be as high as 125 degrees, and the lubrication test of the oil is really heavy. It is also recommended to replace the coolant, which can increase the boiling point of the coolant, so that the cooling system can give full play to the heat dissipation efficiency. It is recommended to use the coolant launched by VP. In addition, there is brake oil. It is recommended to use DOT 4 or even DOT 5.1 oil as much as possible, which can better cope with the braking force when the brake is high temperature.
Also, check the thickness of the brake pads and the disc. If you think the brake pads are not enough, or the thickness of the two is less than 50%, it is recommended to replace them with new ones with a higher friction coefficient. Pads and discs with sufficient thickness, because the pads will be used quickly when going off the track. If the thickness is not enough or the friction coefficient is insufficient, the brakes will not be able to be stepped on soon; too thin discs will also heat up due to Too fast and harden or even deform. In addition, you can also consider replacing the metal brake hose, which can not only increase the firmness of the brake pedal, but also reduce the problem of pressure loss after the thermal expansion of the rubber hose.
As for tires, it depends on the way you drive to decide whether to use general performance tires or hot melt tires, but they suggest that if you want to drive happily off the track, it will be safer to use better tires, and it will be less difficult to drive. It will tie hands and feet. If the budget is enough, you can consider the BS RE-71RS hot melt tire. It is the highest rated tire among players at present, but the relative price is also high. Others like modified shock absorbers, reinforced anti-roll bars, reinforced body tie rods, lightweight rims, or multi-piston calipers, etc. If you have a budget, of course, it is recommended to replace or install them, but I think that the vehicles that will participate in the track walking meeting, It should have undergone different levels of chassis modification. If it is not changed to full, you can adjust the driving style according to the limit of the vehicle. Don't force the limit of people and vehicles, and you can still have a good time. It is worth mentioning that before participating in the event, remember to put the vehicle on top. In addition to four-wheel alignment, you should also ask a technician to check whether every important screw of the suspension system is loose, whether the oil core is locked, etc. These are all to ensure the safety of the vehicle. important items.
