Porsche 911 GT3 R

TYRES

• Slick (Dry compound), Front 1.95 bar, Rear 1.90 bar — these are hot/rolling targets for single-lap attack; set cold pressures ~0.15 bar lower to reach target after 1 warm-up lap. Tyre blanket temp: 80°C F/R. Optimal operating window for max grip: 90–100°C (front), 85–95°C (rear).

ELECTRONICS

• TC1: 3 (minimal intervention for max rotation/exit aggression)
• TC2: 1
• ABS: 4
• Brake Pressure: 100%
• Brake Bias: F: 54% / R: 46%

DRIVETRAIN

• Fuel Map: Map 1 — maximum power, richest mixture, no fuel saving (single lap, irrelevant consumption)
• Gear Ratios:
• 1st: 3.200
• 2nd: 2.550
• 3rd: 2.100
• 4th: 1.780

DAMPERS

AERO

• Front Splitter: 6 (clicks, max attack front load)
• Rear Wing: 8 (high-downforce setting, Nordschleife needs stability over top speed)
• Downforce Level: High
• Brake Ducts: F 2 / R 3 (minimal cooling needed for single lap, reduce drag)

KEY SETUP NOTE

• At Nordschleife, rear ride height stability through compressions (Fuchsröhre, Adenauer Forst) is critical — running it too low risks bottoming and snap oversteer on exit kerbs; the 65mm rear height with stiffer ARB keeps the platform controlled while still allowing the high coast lock to stabilize entry into the track's many blind, off-camber corners.

TRACK GUIDE

• Brake extremely late into Adenauer Forst and Bergwerk — trail brake deep to rotate the rear-engine weight transfer, but respect the coast diff lock to avoid snap rotation.
• Through the Flugplatz and Schwedenkreuz kerbs, commit to full throttle early — the high rear wing and stiff rear ARB keep the car planted over compressions at high speed.
• Fuchsröhre's compression at the bottom loads the rear hard; carry maximum speed but be ready for slight bottoming — ride height is tuned to handle this.
• Traction out of Karussell (the banked corner) is vital — unwind the wheel progressively and let the power diff (0.3) allow slight rear slip for rotation without wheelspin.
• Lap time is won in the flowing middle sector (Hatzenbach to Flugplatz) through minimum lift-off sections — precise, confident steering inputs with this stiffer setup reward smoothness over abrupt inputs despite the aggressive philosophy.
