McLaren 720S GT3 Evo

TYRES

• Dry compound (slick). Front 26.5 PSI / Rear 26.0 PSI cold set pressures — target hot pressure 27.0–27.5 PSI front, 26.5–27.0 PSI rear. Optimal operating window for this compound: 85–95°C for maximum grip (peak slip grip around 90°C). Reference lap (30°C air/37°C track) ran slightly low hot pressures front — raising cold base by ~0.3–0.4 PSI to compensate for a true "fast" dry session and avoid under-pressure on a long single lap. Tyre blanket temp: 80°C all four (standard pre-heat, let first flying lap bring them to window).

DAMPERS

AERO

• Front splitter: 2 (minimum drag priority — Monza top speed)
• Rear wing: 3
• Downforce level: Low — biased for straight-line speed, enough rear wing to keep stability through Parabolica and Ascari
• Brake ducts: Front 2 / Rear 2 (single lap — minimal cooling need, prioritize low drag)

KEY SETUP NOTE

• On a single qualifying lap at Monza, the 720S's long gearing and low-drag setup rewards a slightly stiffer front/softer rear balance to rotate hard into both chicanes without inducing snap oversteer on exit — keep rear ARB soft and lean on mechanical diff coast lock for chicane stability rather than aero, since every click of rear wing costs top speed on the two long straights.

TRACK GUIDE

• T1/2 (Rettifilo): brake as late as possible in a straight line, trail slightly into the first apex, use the stiffer front end to rotate hard over the second kerb — don't lift mid-chicane.
• T3 (Curva Grande): taken essentially flat or lifted minimally — commit early, trust rear stability from diff coast setting.
• T4/5 (Roggia): similar to T1/2 but faster entry — brake in a straight line, downshift early, prioritize a clean rotation over max entry speed to protect exit onto the back straight.
• Lesmo 1/2: Lesmo 1 needs strong front bite on entry (use trail-braking rotation); Lesmo 2 is where time is lost to understeer — carry slightly less entry speed to protect exit speed onto the straight to Ascari.
• Ascari chicane: flat, stable ride over kerbs is critical — don't unsettle the car on entry, use the stiffer front wheel rate to stay flat, exit wide for min
