Porsche 919 Hybrid 2016

• Note: The Porsche 919 Hybrid 2016 is an LMP1 Hybrid prototype, not a GT3 car — the parameter context supplied (GT3 R road-relevant notes) does not directly apply. I'm applying appropriate LMP1-hybrid-prototype logic (slick compounds, hybrid energy deployment, high downforce aero, low-profile ride heights) using the same scale conventions (PSI, N/m, Ns/m) requested.

TYRES

• Slick (Michelin LMP1 spec), front 26.5 PSI cold → target ~28–29 PSI hot, rear 27.0 PSI cold → target ~29–30 PSI hot. Tyre blankets on if session allows — set to 80°C front/rear. Optimal operating window for these slicks: 90–100°C, peak grip ~95°C.

ELECTRONICS

• TC: 2 (minimum intervention, hybrid torque-fill makes high TC unnecessary)
• ABS: 1 (barely-there, for late-braking stability only)
• Engine Braking: 4 (mid-high, helps rotation into La Source/Les Combes)
• Brake Bias: 54.5% front (base, see brake bias line below)
• ERS/Hybrid Deployment: Full deployment mode — manual boost button armed for Kemmel Straight exit and Blanchimont-to-Bus Stop; deploy from apex of Rivage and La Source for max exit speed.

SUSPENSION

• // FRONT

• Brake Bias: 54.5 %
• // REAR
• Ride Height: 34 mm
• Wheel Rate RL / RR: 155000 N/m / 155000 N/m
• ARB: 180000 N/m
• Diff Preload: 60 Nm
• Diff Coast: 0.35
• Diff Power: 0.50

DAMPERS

AERO

• Front splitter: 3 (of 6), Rear wing: 5 (of 8), Downforce level: medium-high — Spa favours drag reduction on Kemmel over outright Eau Rouge grip, biased slightly toward efficiency. Brake ducts: front 2 / rear 3 (of 6).

KEY SETUP NOTE

• The 919's hybrid torque-fill through Eau Rouge/Raidillon compression can unsettle the rear mid-corner if deployment is full-throttle from apex — short-shift the boost activation point 10m later than instinct dictates to keep the rear planted through the compression before unleashing full power on Kemmel.

TRACK GUIDE

• La Source: brake as late as the carbon discs allow (~115m marker), trail into apex, get hybrid deployment active from mid-corner for the long run to Eau Rouge.
• Eau Rouge/Raidillon: flat in this car with full fuel and correct rear ride height — any lift costs 3-4 tenths; trust the aero platform, stay full throttle, delay hybrid boost until past the crest.
• Les Combes: heaviest braking zone on track after Kemmel — brake in a straight line, late apex to maximize kerb use on exit for Malmedy.
• Pouhon: this is where LMP1 downforce wins the lap — carry massive min-speed through both apexes, barely lift.
• Blanchimont: flat-out in quali trim; this is the biggest time gain over slower classes — any hesitation here costs more than any other corner on track.
