[Refitting actual combat]JK Racing BRZ factory car appeared (Part 2)Specially modified for 1 small endurance race

The chassis is fully modified and strengthened

The original wheel base is widened by 2cm

Since this BRZ is used for off-track participation in official competitions, the modification and strengthening of the chassis are also indispensable. For this reason, the front wheel part has been replaced with a reinforced tripod + adjustable Lizai string, with JK Racing SS2 2Way external nitrogen cylinder The high-performance shock absorber, this group of shock absorbers can provide 32-stage damping soft and hard adjustable design on the telescopic side, plus the use of the well-known Hypercoils spring and adjustable fisheye upper seat, which can provide a variety of intense driving on the track. required. The rear wheel has been strengthened to a higher degree. At present, a special rear tilt angle adjuster and a rear toe angle adjuster have been installed. It is matched with the same JK Racing SS2 2Way external nitrogen cylinder shock absorber as the front wheel to provide better rear wheel control limit. set up.

For the appearance, in order to meet the high-speed cornering requirements of the track, the front and lower spoilers and left and right fixed wings have been installed on the front of the car. The GT rear wing is used for testing. Even if it is not a special rear wing, it still strengthens the downforce and visual tension of the rear of the car. In the braking part, the front wheels have been replaced with the opposite six-piston calipers introduced by JK Racing, and the discs are also made of carbon fiber, which greatly improves the heat exhaustion resistance of the braking system, and also achieves excellent vehicle weight and lightweight effects. However, the use of ceramic brakes The disc must develop the habit of raising the working temperature in order to exert a strong braking effect in an emergency, which reminds the reader a little.

It is worth mentioning that the central drive shaft of this car has also been replaced with carbon fiber parts, so the speed of pulling and turning will be significantly improved, and it can also reduce the weight of the car. In the past, carbon fiber drive shafts have always had the problem of insufficient durability. Especially in the face of vehicles with excessive torque, the situation of turning off is a little heard. However, with the recent progress in the process, the above has been improved a lot. For a naturally aspirated engine that is concerned about weight and horsepower, a little less load means more. A little odds.

At the end of the interview, Jimmy also told the author that the left and right track of the rear wheels of the new BRZ is increased by 1 cm in size, but he himself thinks that it should be more than 1 cm. The BRZ is about the same width, and the modified rims of the old BRZ all run out of the wheel arch, so the stability for high-speed cornering must be much better than the old one.

This car will undergo some enhancements before the competition in June. The participating group will be the S2000 group. This group can strengthen the power system, but cannot install the supercharging system, which can be used to verify the modification potential of the new BRZ. , The fastest lap time currently set is about 1 minute and 57 seconds. If it is faster, there is no problem. However, considering that the type of competition is an endurance race that requires running for 60 minutes in each round, finding a way to finish the race is the final The ultimate goal, it’s useless to go as fast as a lap without finishing the race, so it is a test of the skills of the tuner. As for the final result, we will look forward to the performance of this BRZ in the June race.
