Porsche 911 GT3 R (992)

TYRES

• Dry compound (slick), front 27.2 PSI, rear 26.8 PSI cold set. Blanket temp 70°C front/rear if used. Optimal operating window for max grip: 85–100°C (slicks reach peak grip in this band; avoid exceeding ~110°C to prevent falloff). Note: hot lap air/track temps (27/29°C) are mild — slightly higher starting pressures vs base ACC defaults recommended to reach operating window quickly on an out-lap/single hot lap.

DAMPERS

AERO

• Front splitter: 2
• Rear wing: 4
• Brake ducts: Front 2 / Rear 2 (minimal cooling needed — single hot lap, no thermal buildup concern)

KEY SETUP NOTE

• Monza rewards minimum drag above all else — this Porsche's low-drag rear wing setting (4) combined with a slightly firmer rear ARB and higher coast lock keeps the pendulum-prone rear stable under the brutal chicane braking zones (T1/2, T4/5) without sacrificing the top-speed gain on the two long straights, where this car's lap time is truly won or lost.

TRACK GUIDE

• T1/2 (Rettifilo): Brake as late as physically possible in a straight line — trail very lightly, let the car rotate over the kerbs on exit; aggressive kerb riding is fine but keep steering inputs minimal to avoid unsettling the rear.
• T3 (Curva Grande): Taken near-flat — commit early, trust the aero; any lift costs significant minimum speed carried onto the straight.
• T4/5 (Roggia): Second heavy brake zone — similar to T1 but slightly earlier turn-in is needed; don't carry too much speed into the first kerb or the rear will step out on exit.
• Lesmo 1/2: Lesmo 1 needs strong front bite on turn-in (trail-brake slightly) — Lesmo 2 is where understeer creeps in, so get the rotation done early and get back to power progressively to protect exit speed onto the back straight.
• Ascari chicane: Stay flat and stable over the kerbs — small, precise inputs; this is a rhythm section, not an attack point.
• Parabolica: This is the lap-time corner — late apex, patient on throttle application, maximize exit speed for the full-throttle run to the line; a small sacrifice in mid-corner speed for better exit pays off massively here.

TYRES

• Wet compound, Front 28.0 PSI, Rear 27.5 PSI (wet tyres run hotter under spray/standing water — slightly higher start pressure than dry baseline to reach window faster). Optimal operating temperature: 55–65°C for wet compound (vs 75–90°C for dry). Blanket temp: 50°C (max allowed heat soak before green flag running).

DAMPERS

AERO

• Front Splitter: 4, Rear Wing: 6, Brake Ducts Front: 4, Brake Ducts Rear: 4 (increased cooling/drag tolerance acceptable — low top speed demand in wet, prioritise stability and tyre temp retention over outright drag reduction)

KEY SETUP NOTE

• In the wet, the 911 GT3 R's rear-engine weight bias becomes a double-edged sword: traction out of the chicanes is excellent, but aquaplaning risk and reduced front bite under braking means you must soften front ARB and raise front ride height slightly versus dry setup — this restores front end rotation into Lesmo and the Ascari chicane without snap oversteer on throttle application.

TRACK GUIDE

• Variante del Rettifilo (T1/2): brake 15-20m earlier than dry reference, straight-line only — any trail-braking rotation in the wet here will spin the rear; use full ABS trust and release progressively.
• Curva Grande (T3): lift only fractionally — full commitment is not possible in wet; watch for standing water on the outside kerb line, stay center-track.
• Variante della Roggia (T4/5): same early braking philosophy as T1/2; this is where most wet-lap time is lost to overcautious drivers — brake firmly but in a straight line, rotate only after speed is scrubbed.
• Lesmo 1 & 2: patience on throttle — wait for the wheel to straighten before full application; second apex (Lesmo 2) is where rear steps out if power is applied early, costing exit speed onto the back straight.
• Parabolica: this is THE lap-time corner in the wet — a slow, geometric entry with earlier, smoother throttle application beats a fast entry with a correction; every mph gained here is free on the following straight.
