Porsche 911 GT3 R Rennsport

TYRES

• Front Pressure: 26.5 PSI
• Rear Pressure: 26.0 PSI
• No tyre blankets (AC Evo — not applicable)
• Optimal operating temp: 85–95°C (peak grip window, front and rear)

ELECTRONICS

• TC1: 3 (aggressive, rotation-focused, low intervention for qualifying)
• TC2 (slip ramp): 2
• ABS: 5
• Engine Braking: 4 (reduces entry instability through S-complex)

• Wheel Rate FL / FR: 145000 N/m / 145000 N/m
• ARB: 4 (medium-soft, aids front turn-in through Schumacher-S)
• Brake Torque Multiplier: 100%
• Brake Bias: 56.5%
• // REAR
• Ride Height: 58 mm
• Wheel Rate RL / RR: 175000 N/m / 175000 N/m

DAMPERS

AERO

• Front Wing: 4 (clicks, maximizes front grip for S-complex without excess drag)
• Rear Wing: 8 (high — Porsche-specific trait, stabilizes rear for Mercedes-Kurve and Bit-Kurve exits)
• Downforce Level: High-medium balance, biased rear
• Brake Ducts: Front 2 / Rear 2 (single lap — minimal cooling need, prioritize aero tightness)

KEY SETUP NOTE

• With tyre wear irrelevant and only one lap on cold-to-optimal-window tyres, run slightly higher rear ARB and strong coast lock (0.75) to mask the 911's rear-engine pendulum effect under the heavy trail-braking needed into the Yokohama-S and Castrol-S — this prioritizes rotation confidence over long-run stability, which doesn't matter for a single hot lap.

TRACK GUIDE

• Yokohama-S (T1): Brake extremely late, trail into apex — stiffer rear ARB lets you rotate hard without snap; carry speed through the second apex.
• Castrol-S (T3): Minimize steering corrections — the GT3 R's wide front track rewards precise, early turn-in rather than mid-corner correction; sacrifice nothing on exit.
• Mercedes-Kurve (T7): Long rear-loaded sweeper — trust the high rear wing, stay full throttle if tyres are in window, let rear squat naturally.
• Dunlop & Bit-Kurve hairpins (T5
