McLaren 720S GT3 Evo

TYRES

• Slick — Soft (Qualifying). Front pressure: 26.8 PSI cold | Rear pressure: 26.3 PSI cold
• Tyre blanket temp: 80°C (standard ACC blanket setting)
• Optimal operating window for max grip: 85–100°C (tread surface), peak grip centered around 90°C. On a single hot lap, aim to cross La Source and Les Combes with fronts already at 85°C+; rears must hold 80°C+ through Eau Rouge for stability.

ELECTRONICS

• TC1: 4 (low — max rotation, aggressive driver compensates manually)
• TC2: 2
• ABS: 5
• Engine Map: 1 (max power, qualifying fuel irrelevant)
• Brake Bias: 58%
• Brake Driver Sensitivity: 80%

SUSPENSION

• // FRONT
• Ride Height: 52mm
• Wheel Rate FL / FR: 190 N/mm / 190 N/mm
• ARB: 8
• Brake Torque Multiplier: 100%
• Brake Bias: 58%
• // REAR
• Ride Height: 58mm
• Wheel Rate RL / RR: 165 N/mm / 165 N/mm
• ARB: 6
• Diff Preload: 120 Nm
• Diff Coast: 0.65
• Diff Power: 0.45

DAMPERS

AERO

• Front Splitter: 6 | Rear Wing: 8 | Brake Ducts Front: 3 | Brake Ducts Rear: 4
• Downforce bias leans rear-heavy intentionally — Eau Rouge/Raidillon and Blanchimont demand a planted rear over outright Kemmel top speed.

KEY SETUP NOTE

• The 720S snaps on entry/compression if rear roll stiffness is too aggressive relative to the front — keep rear ARB softer (6) than instinct suggests and let the higher rear wing (8) and slightly stiffer rear spring carry Eau Rouge/Raidillon compression without sudden rear load loss; this is the single biggest lap-time risk/reward zone on the entire circuit.

TRACK GUIDE

• La Source: brake extremely late but in a straight line — trail brake only lightly, the 720S front wants to grip hard; rotate mid-corner and get on power early for Kemmel run.
• Eau Rouge/Raidillon: full commit flat-out if speed permits; stay dead straight on the kerbs, any lift destabilizes the rear — this is where setup confidence must exceed raw car feel.
• Les Combes: late, hard brake into chicane; use ABS 5 to find the limit — slight rear rotation on entry is fine here due to coast diff lock (0.65).
• Pouhon: commit to high minimum speed in first apex, trust front aero (splitter 6) — a stable platform here is where time is made, not lost.
• Blanchimont: near-flat is achievable with this setup's rear stability; treat it like Eau Rouge — any hesitation costs 2-3 tenths minimum.
• Bus Stop: aggressive kerb use on entry curbing, sacrifice nothing — stiffer front damper settings keep platform stable over aggressive kerb strikes.
