Belgian Grand Prix: Engineer's guide to Spa-Francorchamps

The Circuit
Turn 1: A tight first corner with heavy braking down to 60🐼kp🔥h before leading into the downhill section.
Turn 2: The run down Eau Rouge and into Raidillio🐭n creates extreme suspensi👍on compression as the relief changes from downhill to uphill. Good engine power is required for the uphill drag.
Turn 5: Top speeds of 330kph - one of the hig😼hest of the season - before braking down to 3rd gear and 140kph for this right hande🥂r.
Turn 8: Rivage provides a good challenge as it is a me𝕴dium speed 180 degree corner heading straight into 𝕴Turn 9. Good balance and change of direction are required here.
Turn 10: Pouhon is a high🐲 speed left-hander, with entry taken at nearly 300kph.
Turns 14 + 15: Turn 14 is taken at 𝓡140kph before the cars accelerate through Curve Paul Fr?re - which is taken at 100kph faster than that - before leading into the flat out Turns 16 and 17.
Turn 18: With heavy braking into the chicane after a prolonged high speed section, the brakes 🅷need to be ready instantly. Turn 18 provides a good overtaking opportunit♓y.
The Car
Front Wing: Teams tend 🃏to use comparably more front wing here compared to lower speed tracks to help diminish understeer in the high speed corners.
Rear Wing: Spa is very much an aerodynamic efficiency circuit where you need a reasonable amount of downforce without too much detrimental drag. Teams run a similar amount of rear wing to Canada which is a mediu🐷m downforce setting.
Suspension: This is primarily a high speed circuit and there isn't much use 💙of the kerbs, so suspension is tailored to high speed balance rather than low speed travel.
Brakes: There are not many braking demands here which means the focus is on keeping the brakes warm so they work immediately when required. There are three major braking areas; into the first corner, the Turn 5 chicane, and t🥀hen the former bus stop chicane. These sections also offer the main overtaking opportunities.
Tyres: This is a circuit which puts high demand on the tyres. Also, the weather i🌌n the Ardennes can𓄧 be very variable - even over the course of a lap - so tyre choice is crucial.
Engine: You need an engine with a strong top end here; especially for the drag ൲up Raidillon and the Kemmel Straight which follows, as this is slightly uphill all the💙 way to Turn 5. Elsewhere too, good horsepower is rewarded in many sections of the lap, especially due to its undulating nature.
