Porsche 911 GT3 R 2016

TYRES

• Slick (Soft), front 23.5 PSI cold / rear 23.5 PSI cold — target hot pressure ~27 PSI all corners. Optimal slick operating window: 85–95°C core temp for peak grip. Blankets (if session allows) set to 80°C; if off, build temp gradually across out-lap, expect first 2 corners well below window.

ELECTRONICS

• TC: 2 (minimal, just enough to catch Eau Rouge compression and Rivage exit on cold rears)
• ABS: 1 (minimal, aggressive late braking into La Source and Les Combes still needs some stability)
• Engine Braking: 4 (mid setting, helps rotation on trail-brake without upsetting rear on corner entry)
• Brake Bias: 56.5% front (see Suspension section)

SUSPENSION

• // FRONT

• Brake Torque Multiplier: 100%
• Brake Bias: 56.5%
• // REAR
• Ride Height: 60 mm
• Wheel Rate RL / RR: 130000 N/m / 130000 N/m
• ARB: 32000 N/m
• Diff Preload: 60 Nm
• Diff Coast: 0.4
• Diff Power: 0.6

DAMPERS

AERO

• Front splitter: 4 (of typical 0–6 range for this car)
• Rear wing: 6 (of 0–10 range) — Spa favors reduced drag for Kemmel speed but Eau Rouge/Blanchimont stability demands this minimum; do not go lower on single-lap attack, the time lost to instability exceeds straight-line gain
• Brake ducts: 3 front / 3 rear (single lap, no thermal concern, keep minimal for aero cleanliness)

KEY SETUP NOTE

• This car's rear-weighted, rear-engine platform makes Eau Rouge/Raidillon the single biggest risk on this lap — the compression plus the car's natural pendulum tendency means any rear instability there is catastrophic and slow to correct. The entire rear suspension (spring, ARB, damper) above is tuned slightly stiffer in rebound than typical to control squat through the compression while keeping the rear planted; resist the urge to soften the rear further for Rivage traction — find traction from diff and power delivery instead.

TRACK GUIDE

• La Source: brake as late as possible but in a straight line — this car's front loads heavily under trail braking due to rear weight bias, so get braking done early-ish in the zone and rotate on trail, not on entry shock.
• Eau Rouge/Raidillon: full commit flat (or near-flat) only if the rear platform is settled from Kemmel — any unsettled rear here compounds through Raidillon's crest; stay central, smooth input.
• Les Combes: this is where time is won — late, hard braking stable in a straight line, use the ABS floor aggressively, rotate mid-corner using front grip (not throttle) given diff coast setting.
• Pouhon: this double-apex needs committed front end — trust the splitter/wing balance, carry speed through first apex, let rear stability (your tuned ARB/damper rear) hold the platform through the second.
• Bus Stop: aggressive kerb use is fine with this ride height, but don't overslow entry — the exit onto the straight matters more than the chicane's apex speed; prioritize a clean, powerful exit.
