A japanese car and a japanese driver in a japanese track

Suzuka is one of the oldest and most-famous racing circuits in Japan. The track is returning to F1 calendar this year. Suzuka is considered a "driver circuit", where the driver can be more significant than the car to turn a good lap time. The circuit requires a driver well concentrated and in good physical condition. Let´s see the key features to make a good lap here:

Aerodinamics: medium to high downforce (8/10). Is needed a good high-speed balance because there are a lot of medium and high speed changes of direction.
Brakes: brakes aren't the problem in Suzuka. The circuit is one of the two lightest circuits on brakes overall, because you don't have the combination long straight/low speed corner which hurts the brakes.
Suspension: mechanical grip is important here, to get good clean exits out of the slow corners and a car that can ride the bumps and any changes of camber. Soft suspension helps at the bumps of the track.
Engine: a powerful engine is required in Suzuka, mainly because of of the uphill curves and the long straight in the and of the lap.
Gearbox: medium acceleration, the transition between gears have to be smooth to give stability during the sequence of curves.
