Ford Mustang GT3

TYRES

• Slick (dry compound), Front 26.5 PSI cold, Rear 26.0 PSI cold. Optimal operating window: 85–105°C (peak grip ~95°C). No blanket use — out-lap tyre management required to reach window before hot lap.

ELECTRONICS

• TC1: 4. TC2: 2. ABS: 5. Engine Braking: Medium-High (6/10). Brake Bias: 54.0% front (adjustable to 55.5% for T1/T5 under max attack).

SUSPENSION

• ARB: 220000 N/m
• Brake Torque Multiplier: 100%
• Brake Bias: 54.0%
• // REAR
• Ride Height: 60 mm
• Wheel Rate RL / RR: 120000 N/m / 120000 N/m
• ARB: 160000 N/m
• Diff Preload: 55 Nm
• Diff Coast: 0.5
• Diff Power: 0.75

DAMPERS

AERO

• Front splitter: max attack setting (position 5/5). Rear wing: 6 (of 8) — balanced top-speed/downforce for T3-T4 commitment. Downforce level: High-Medium. Brake ducts: Front 4/6, Rear 3/6 (single-lap, no thermal derate concern).

KEY SETUP NOTE

• With tyre wear irrelevant, run slightly lower rear pressure and firmer power diff lock than race setup — this maximizes rotation on T2/T9 exits without the usual wear penalty, converting directly into straight-line speed down the two longest straights.

TRACK GUIDE

• T1 Castrol Kurve: Latest braking point of the lap — brake deep, trail hard, let rear rotate; stability from high brake bias and ABS 5 lets you carry extra 3-4 km/h in.
• T3/T4: Committed flat-ish sequence — car goes light over the crest at T4, keep steering inputs smooth, any lift costs massive time on exit onto the back straight.
• T5 Jochen Rindt: Second biggest braking zone — trail brake into the right-hander, resist the urge to turn in early, apex late to open T6/T7 exit.
• T9 Hans Ernst: The lap-defining corner — sacrifice entry speed for a clean, early throttle application; power lock diff (0.75) pins the rear down for max straight speed to the line.
• Biggest time gain: minimizing throttle hesitation out of T2 and T9 — this V8's torque rewards committed, progressive throttle over late apex speed.

THEORETICAL BEST LAP

• 1:13.800 — simulated optimal based on GT3-class pace at Red Bull Ring GP, dry, low fuel, qualifying tyres, iRacing physics.

REAL WORLD RECORD

• 1:21.057 — Christopher Mies, Audi R8 LMS GT3, 2020 ADAC GT Masters Qualifying (closest official GT3 class reference; exact Mustang GT3 record not established).
