DAMPERS

AERO

• Front Splitter: 4 (of 6 clicks — aggressive, balanced against rear)
• Rear Wing: 6 (of 8 — high downforce for Pouhon/Blanchimont stability, accepting Kemmel drag loss)
• Downforce Level: High-biased, tuned for rear planted feel over top speed
• Brake Ducts Front: 2 (of 6 — quali lap, minimal cooling needed)
• Brake Ducts Rear: 2 (of 6)

KEY SETUP NOTE

• On a single hot lap, prioritize rear platform stability through Eau Rouge-Raidillon compression and Blanchimont — a rear wing at 6 with slightly softer front ARB lets you carry more speed through these flat-out sections without lifting, which is worth more time than outright straight-line speed lost on Kemmel.

TRACK GUIDE

• La Source: brake extremely late (150m marker), trail brake deep to rotate the nose, get on power early for Kemmel run — this exit defines your straight-line speed for the entire lap.
• Eau Rouge/Raidillon: commit flat if wing/ride height stable — do not lift mid-compression, stay full throttle from the left kerb through to the top, let the aero and stiffer rear damping absorb the load.
• Les Combes: brake in a straight line before turn-in, aggressive late brake but avoid trail-braking too deep — this car rewards a stable platform here over rotation.
• Pouhon: carry min speed high, trust front grip from -3.7° camber, single smooth arc through both apexes — lost time here compounds through Fagnes.
• Bus Stop: sacrifice a strict racing line to ride the inside kerb hard on entry — the stiffer wheel rates let you attack the kerbs without un
