As you approach corner 4, focus on your braking point. Begin braking approximately 39 meters after the turn-in, as this is the optimal distance to slow the car down to the minimum speed of 79 km/h in 3rd gear. Maintain a smooth, progressive brake application, and be ready to transition to the throttle as you reach the apex of the corner. Remember to keep your steering inputs precise and avoid any sudden movements. By following this braking technique, you can carry good speed through the corner and set yourself up well for the exit. Stay focused and trust your abilities - you've got this!
