Mercedes-AMG GT3

TYRES

• Slick (Soft compound), Front 23.5 PSI cold / target ~27.5 PSI hot, Rear 23.0 PSI cold / target ~27.0 PSI hot. Optimal operating window for this slick compound: 85–95°C (peak grip ~90°C). No tyre blankets assumed — first sector driven to build temp if cold session start.

ELECTRONICS

• TC: 2 (minimal, just enough to catch rear snap on Döttinger exit and Bergwerk)
• ABS: 3
• Engine Braking: Medium (setting 3 of 6)
• Brake Bias: 54.0% front (adjustable in cockpit, see below)

DAMPERS

AERO

• Front Splitter: 4 (of available steps), Rear Wing: 6, no brake duct adjustment on this model (fixed cooling) — if ducts present, set 2/2 medium.

KEY SETUP NOTE

• The Mercedes' mass and long wheelbase punishes mid-corner trail braking if the front isn't given extra bite early — run slightly stiffer front ARB and lower front ride height than "safe" GT3 baseline to force rotation into Adenauer Forst and the Karussell entry, accepting slightly more rear nervousness at Flugplatz and Schwedenkreuz that the diff power setting (0.6) and rear damper rebound control to prevent snap.

TRACK GUIDE

• Hatzenbach: stay full commitment, trust the compliant suspension over bumps — don't lift mid-corner, let the car ride the kerbs flat.
• Flugplatz: car goes light over the crest — hold a dead-straight line, no steering input at the crest or the rear will step out on landing.
• Fuchsröhre: brake before the compression, not during — heavy compression loads the springs hard; late braking here costs rear grip into the fast right.
• Karussell: take the banking fully, inside kerb loaded — carry more speed than feels natural, the banking adds mechanical grip even on a heavy GT3.
• Döttinger Höhe: this is where lap time is won — the Mercedes' power and stable long wheelbase are strongest in a straight line, carry maximum minimum-corner-speed out of the last chicane before it.
