Monaco is a unique circuit, but it no longer has unique high-downforce requirements for Formula 1 teams.
Increasingly, teams are running high downforce at most tracks, but Monaco doesn't have a sensitivity to drag compared to conventional circuits, as the average speed is so slow. As a result, teams do not tend to produce the extreme Monte Carlo aero set-ups that we have seen in the past. But the same basic tricks still apply: maximum downforce, raised suspension, and bodywork trimmed to allow maximum turning angle.
Brakes run at high temperatures here, mainly because the callipers and brake fluids retain heat, rather than because of elevated disc temperatures.
