Porsche 911 GT3 R 2016

TYRES

• Slick (Soft compound if available), Front 23.5 PSI cold / ~27.5 PSI hot target, Rear 23.0 PSI cold / ~27.0 PSI hot target. Optimal operating window for GT3 slicks: 85–95°C, peak grip ~90°C. No tyre blankets assumption — first lap must build temp through Sector 1's long runs before Eau Rouge.

ELECTRONICS

• TC: 3 (minimal, allows rotation on throttle)
• ABS: 2 (low intervention, trail-braking friendly)
• Engine Braking: 4 (mid, stabilizes rear into low-speed corners without killing rotation)
• Brake Bias: 54.5% front

DAMPERS

AERO

• Front Splitter: 4 (of typical 0–6 range, aggressive but keeps front planted through Eau Rouge/Pouhon)
• Rear Wing: 7 (of 0–10, high downforce for Pouhon/Blanchimont commitment, accept minor straight-line loss on Kemmel)
• Brake Ducts: Front 2 / Rear 2 (cold track, single lap — no thermal buildup concern)

KEY SETUP NOTE

• Spa demands a setup that is planted through the high-speed Eau Rouge–Raidillon–Kemmel sequence and Pouhon, yet this rear-engined GT3R will still want to rotate late at La Source and Les Combes — run slightly more rear wing than front splitter to protect high-speed stability, and lean on the coast diff (0.4) rather than a stiffer rear bar to get rotation into the slow corners, keeping the pendulum effect manageable.

TRACK GUIDE

• La Source (T1): Brake very late but in a straight line before turn-in — this rear-engine car's weight transfer rewards trail-braking lightly to rotate, but don't overdo it or the rear will snap on exit.
• Eau Rouge-Raidillon: Full commitment flat or near-flat depending on fuel/wing — car must be perfectly straight over the kerbs; any mid-corner steering input here with this setup risks instability on the crest.
• Pouhon (T9-10): Two long left-handers taken at high speed — this is where rear wing (7 clicks) pays off; trust the aero, late apex the first part to set up a tighter line for the second.
• Les Combes (T5) and Bus Stop Chicane: Key traction zones — get the car rotated early with coast diff before full throttle to maximize exit speed onto Kemmel straight and into the final sector.
• Blanchimont: Flat-out in quali trim — the
