Porsche 911 GT3 R (992)

TYRES

• Compound: Dry (GT3 slick)
• Cold pressures: Front 27.0 PSI (both), Rear 26.5 PSI (both). Race stint, full fuel, hot targets 27.0–27.5 PSI front and 26.5–27.0 PSI rear after 3–4 laps.
• Optimal operating temperature: 80–90 °C core (peak grip ~85 °C). Above 95 °C expect rapid deg, so drop 0.2 PSI if hot pressures exceed 28.0 PSI.
• Tyre blanket: not applicable (no blankets in ACC).

ELECTRONICS

• TC1: 3
• TC2 (TC cut): 3
• ABS: 4
• Engine map: 1 (the reference lap's map 8 is outside the 1–6 scale, so default to the standard race map; use 2–3 only for fuel saving late in the stint).
• Brake bias: 58.5%
• Brake driver sensitivity: 100%

SUSPENSION

• // FRONT
• Ride Height: 55 mm
• Wheel Rate FL / FR: 130 N/mm / 130 N/mm
• ARB: 3
• Brake Torque Multiplier: 100%
• Brake Bias: 58.5%
• // REAR
• Ride Height: 66 mm
• Wheel Rate RL / RR: 140 N/mm / 140 N/mm
• ARB: 5
• Diff Preload: 90 Nm
• Diff Coast: 0.7
• Diff Power: 0.4

DAMPERS

• (Values on the ACC 1–11 click scale.)

AERO

• Front splitter: 3
• Rear wing: 6
• Downforce level: Medium-high, with extra rear wing for stability over the crest at T4/T5 and to protect the rears across a stint.
• Brake ducts: Front 3, Rear 2. Short lap with repeated heavy stops from high speed, so this keeps brake temps in range without a large drag penalty.

KEY SETUP NOTE

• The 992's rear weight bias gives huge traction out of T1 and T9, but the same mass makes the rear lift over the T4 crest and pendulum on entry to T5. High coast lock (0.7) with a stiffer rear ARB (5) keeps the rear planted under braking and on lift-off. Keep rear ride height at 66 mm or above, because any lower risks snap oversteer on exit under full fuel. Over a stint, the rear tyres take the punishment from aggressive throttle, so don't chase rotation with a softer rear.

TRACK GUIDE

• T1 Castrol Kurve: Brake in a straight line at 58.5% bias, trail the pedal off gently to the apex, and get the car rotated before the throttle. Overdriving the entry kills the exit onto the straight to T2.
• T3/T4 uphill and crest: Commit through T3 and stay smooth over the T4 crest where the car goes light. Avoid mid-corner lifts that trigger rear snap, and use the kerbs only where the car stays settled.
• T5 Jochen Rindt Kurve: Heavy stop from high speed. Late braking pays here, but be patient on turn-in, as the rear is still settling from the crest. Set the rotation with brake release, not steering angle.
• T9 Hans Ernst Kurve: The most important corner for the lap. Be progressive with the throttle with TC at 3, straighten the car early, and use the rear traction to carry max speed down the main straight.
• Stint management: Lap time is won in T1 braking, T5 braking and T9 exit. Over a stint, protect the rears by avoiding wheelspin out of T2 and T9, and expect a 0.3–0.5 s drop-off after about 12 laps if you push constantly.
