Porsche 911 RSR 2017

TYRES

• Compound: Slick (GT3-spec slick, as fitted to RSR 2017)
• Front pressure: 26.5 PSI cold → target hot 29.0 PSI
• Rear pressure: 26.0 PSI cold → target hot 28.5 PSI
• Optimal operating temperature: 85–95°C core for peak grip window
• Blankets (if session allows): set to 80°C — first lap must still tolerate cold-side grip since quali lap often runs without full blanket soak

ELECTRONICS

• TC: 3
• ABS: 5
• Engine Braking / brake magic: Medium-High (setting 5 of 7, stabilises rear under late trail-braking)
• Brake Bias: 54.5% front

SUSPENSION

• // FRONT

• Brake Torque Multiplier: 100 %
• Brake Bias: 54.5 %
• // REAR
• Ride Height: 60 mm
• Wheel Rate RL / RR: 150,000 N/m / 150,000 N/m

• Diff Coast: 0.6
• Diff Power: 0.3

DAMPERS

AERO

• Front splitter: 4 (of 6 clicks)
• Rear wing: 7 (of 8 clicks)
• Downforce bias: rear-weighted for 130R/Esses stability
• Brake ducts: Front 2 / Rear 3 (of 6) — quali lap, minimal cooling margin needed

KEY SETUP NOTE

• The RSR's rear-engine polar inertia makes 130R and the Esses the defining sections of a Suzuka lap — run max usable rear wing and slightly stiffer rear wheel rate than typical road-course setups to keep the rear planted at 280+ km/h; sacrifice a fraction of chicane rotation rather than risk the rear stepping out through 130R, where any correction costs far more time than the final chicane ever could.

TRACK GUIDE

• T1/T2: Commit full throttle through the first curve on cold tyres carefully — use first sector to build heat before pushing Esses.
• T3–T7 Esses: Never lift. Carry a stable, slightly conservative line (slightly wider entry, earlier rotation) so mid-corner rear squat doesn't snap; smooth steering inputs are essential given the RSR's rear mass.
• T11 Dunlop into T12/13 Degner: Brake in a straight line before turn-in — the RSR's weight transfer punishes trail-braking into blind apexes; get rotation done early, get back to power for hairpin approach.
• T14 Hairpin: This is the biggest time-gain zone — brake deep, rotate late, prioritize a clean, early throttle application for max speed down the back straight.
• T17/T18 130R: Absolute commitment flat or near-flat depending on wing level; the setup's rear stability is built specifically for this corner — trust the rear wing and don't lift early.
