DAMPERS

AERO

• Front splitter: 2 (clicks, low-medium)
• Rear wing: 6 (of typical 1–9 Cup wing scale) — favour stability for Eau Rouge/Blanchimont
• Downforce Level: Medium-High
• Brake ducts: Front 3 / Rear 2 (manage temps over race stint)

KEY SETUP NOTE

• The 911 Cup car's rear-engine weight bias makes Eau Rouge/Raidillon compression the single biggest risk point — slightly higher rear ride height (65mm) and softer rear ARB (10 N/m) versus a pure qualifying setup trades a little rotation for a planted, predictable rear through the compression, which matters more over a full race stint as tyres degrade and fuel load drops.

TRACK GUIDE

• La Source: brake late but straight-line only — trail braking induces snap oversteer with the rear-engine weight transfer; get the car rotated before throttle application for the long uphill exit.
• Eau Rouge/Raidillon: stay flat only once confident in rear platform stability; any lift mid-compression unsettles the rear — commit early, keep steering inputs smooth.
• Les Combes: heavy braking stability is king — brake in a straight line, use the kerb on exit minimally to avoid unsettling the rear on corner exit traction.
• Pouhon: needs patience — trail brake gently to rotate, then progressive throttle; front grip from -3.5° camber should hold the double apex if tyres aren't overheated.
• Stavelot & Blanchimont: both reward a stable rear-biased setup — resist the urge to overdrive entry; time is gained with a clean, early throttle exit rather than outright corner speed.
• Race management: coast lock at 0.65 helps entry stability as tyres degrade late-stint; watch rear tyre temps closely after 20+ min as this car's rear-weight bias accelerates rear deg under aggressive use.
