I was reminded today of the importance of what you are looking at. Vision is your key weapon in your arsenal. It is too easy to get fixated on the apex for too long and as you drive where you are looking this short sighted focus leads you to kill your apex speed and take too long getting back on the gas.
Look at the apex (or slowest point of the corner) as you approach the bend so you are cue’d to brake at the right time. Keep your focus on the apex so you can see the shape of the corner to get your ‘turn-in’ cue and as soon as you turn in lift your vision to the exit. Use your peripheral vision to place the car and concentrate on where you want to end up at the end of the corner and you will find you naturally carry more mid corner speed and get on the power earlier.
