As you approach corner 4, focus on your braking point. Begin braking at the 39-meter mark, then smoothly transition into the turn-in. Maintain a steady throttle application through the apex, allowing the car to settle and grip the road. As you exit the corner, gradually increase your throttle pressure to accelerate out of the turn. Remember to keep the car in 3rd gear throughout this segment. By executing these techniques with precision, you'll be able to carry good speed through this left-hander and set yourself up well for the next section of the track.
