With only the chicanes to punctuate the flat-out sections, and the two Lesmos and the Parabolica both long, challenging turns, Monza is Formula 1's fastest circuit.
For most teams, running the low-downforce, low-drag packages used at the Belgian Grand Prix two weeks ago has sufficed. All are running cut-down front wing flaps and flattened rear wings.
But Monza goes a step further in rewarding a low-drag package. With a large disparity between power outputs from the new engines, some are having try harder than others to trim off wing for better top speed.
