Turn 3 (Entering : “The Omega”)

This corner has two forms of compression: a good amount of on-camber banking as well as the turn goes from flat to uphill.  Both of these greatly increase vertical load on the car and increase grip.

Find a good braking reference point and threshold brake in a straight line on the right side of the road.  Trail off the brakes to an early turn-in to effectively use the banking and compression of the corner to turn the car.  I see a lot of people brake too early and turn-in on throttle and accelerate up the hill.  It is better to carry more entry speed into this turn off-throttle and use the banking and uphill compression to slow and turn the car.  It is important to get a lot of the turning done at the apex since you loose the added grip from the banking and the uphill compression at the end of the turn (there seems to be a theme here).  While entry speed is good, it is important to not slide the car and scrub speed here with excess entry speed because it is a pretty steep hill heading to Turn 4.

Turn 4 (The Balcony/”The Omega”)

While accelerating up the hill, apex the right curbing at the entry of the Omega and keep the wheel straight to drive to the middle of the road.  The road straightens briefly between the two apexes at the top of the hill.  It is not necessary to track all the way to the left side, but it’s important to not hug the right side of the road which will give you a poor exit going back down the hill.  The middle of the track is a good compromise.  Be patient to get back down to the second apex.  It is easy to turn-in early and run out of room when tracking-out.  Be sure to have a good late apex and release the car to track out while accelerating through the apex and down the hill.
