Like birds of a feather, the Spa-Francorchamps and Monza circuits often flock together. The two are neatly aligned in the Formula 1 calendar, and form the last leg of European races ahead of the final set of flyaway rounds.
Both Spa and Monza are fast and sprawling circuits, winding through legions of trees on either side of the respective circuits. And when it comes to developing the right package to maraud the straights for lap time, Formula 1 teams would usually group the two tracks together.
But, contrary to popular belief, they're very different. Just as twin siblings have different personalities, the two circuits require different approaches to their aerodynamic configurations.
