Porsche 992 GT3 R

TYRES

• Compound: Dry — Medium (race distance balance of deg/pace)
• Front Pressure: 1.95 bar
• Rear Pressure: 1.90 bar
• Tyre Blanket Temp: 80°C
• Optimal Operating Window: 85–100°C (peak grip); avoid exceeding 110°C to prevent thermal deg over race stint

ELECTRONICS

• TC1: 5
• TC2: 2
• ABS: 5
• Engine Braking / Brake Magic: Medium (3/5) — aids rotation into S-complex without destabilising rear
• Brake Bias: F: 54% / R: 46%
• Brake Pressure: 92%

DRIVETRAIN

• Fuel Map: Map 3 — balanced mixture, slight lean for fuel saving over long stints while retaining throttle response; switch to Map 1 (rich, max power) for qualifying-style push laps or late-race attack
• Gear Ratios:
• 1st: 3.20
• 2nd: 2.61
• 3rd: 2.19
• 4th: 1.88
• 5th: 1.64
• 6th: 1.43
• Final Drive: 3.65

SUSPENSION

• // FRONT
• Ride Height: 58 mm
• Wheel Rate FL / FR: 145000 N/m / 145000 N/m
• ARB: 95 N/mm
• Brake Torque Multiplier: 100%
• Brake Bias: 54%
• // REAR
• Ride Height: 64 mm
• Wheel Rate RL / RR: 165000 N/m / 165000 N/m
• ARB: 120 N/mm
• Diff Preload: 50 Nm
• Diff Coast: 0.7
• Diff Power: 0.35

DAMPERS

AERO

• Front Splitter: 6 (of 10 clicks)
• Rear Wing: 8 (of 10 — high downforce bias typical for this chassis)
• Downforce Level: High — prioritise rear stability for Mercedes-Kurve and Bit-Kurve traction
• Brake Ducts: Front 4 / Rear 3 (medium cooling — balance brake temp over race stint without overcooling for late-stint bite)

KEY SETUP NOTE

• Rear ride height is the single most sensitive parameter on this car at this track — running it too low will produce snap oversteer on exit of Ford-Kurve and Bit-Kurve under aggressive throttle application; keep rear slightly higher than instinct suggests and lean on the high coast diff lock (0.7) to stabilise entry into the Schumacher-S instead.

TRACK GUIDE

• T1 (Yokohama-S): Brake late but straight-line only — trail braking here with the 911's rear weight bias risks early rotation; get fully straight before re-applying throttle.
• T3 (Schumacher-S): Commit to a stable front end on turn-in; use the high coast lock diff to keep the rear planted through direction changes — this is where aggressive drivers gain over cautious ones if balance is dialed in.
• T5 (Dunlop hairpin) & T11 (Bit-Kurve): Traction is king — delay throttle application fractionally past apex to avoid wheelspin, then ride the power diff (0.35) for drive down the following straight.
• T7 (Mercedes-Kurve): Long rear-loaded sweeper — this is a lap time differentiator; carry min speed higher than feels comfortable, trusting the 120 N/mm rear ARB and high rear wing for stability.
• T13 (Veedol chicane): Don't overslow — sacrifice a fraction of chicane speed to protect exit onto the back straight; time lost here is amplified over the full straight length.
