To prepare the crust, lightly spoon flour into a dry measuring cup, and level with a knife. Place 2/3 cup flour and 2 tablespoons sugar in a food processor; pulse 2 times or until combined. Add chilled butter; pulse 6 times or until mixture resembles coarse meal. With processor on, slowly pour ice water through food chute, processing just until blended (do not allow dough to form a ball). Firmly press mixture into bottom of a 9-inch springform pan coated with cooking spray. Bake at 400° for 10 minutes; cool on a wire rack.
Reduce oven temperature to 325°.
To prepare the filling, beat cheeses at high speed of a mixer until smooth. Add 1 3/4 cups sugar and the next 4 ingredients (1 3/4 cups sugar through salt); beat well. Add eggs, 1 at a time, beating well after each addition.
Pour the cheese mixture into prepared pan. Spoon mounds of Lemon Curd over filling, and swirl together using the tip of a knife. Bake at 325° for 1 hour and 15 minutes or until cheesecake is almost set. Remove cheesecake from oven, and cool to room temperature. Cover and chill for at least 8 hours.
