McLaren 720S GT3 Evo

TYRES

• Slick compound, Front 27.3 PSI cold, Rear 26.8 PSI cold. Qualifying single-lap bias: slightly lower than standard base to account for sharp temperature spike under max attack — target operating window 85–95°C across the tread for peak grip (optimal peak ~90°C). Blanket temp (if used): 80°C F/R.

ELECTRONICS

• TC1: 3 (qualifying, max power delivery — track has long traction zones but good grip at low ambient)
• TC2: 1 (minimal interference, aggressive rotation on throttle)
• ABS: 4
• Engine Braking: Medium (4/6)
• Brake Bias: 54.5% front

DAMPERS

AERO

• Front Splitter: Max (+2 from base, full attack)
• Rear Wing: 5 (of typical 1–6 range, high downforce for stability through Peraltada/Foro Sol complex and traction onto main straight)
• Downforce Level: High — prioritise rear stability for elevation changes and bumpy kerbs
• Brake Ducts: Front 2 / Rear 3 (cooling less critical for 1-lap, keep tyre temp build fast)

KEY SETUP NOTE

• Mexico City's thin air (altitude ~2,200m) drastically reduces aero efficiency — run more wing than you would at sea level to compensate for the ~15-20% downforce loss, and expect the car to feel noticeably "light" under braking into Turn 1 and the Esses; this setup leans into extra rear wing specifically to counteract that altitude-induced instability under late braking and off-throttle rotation.

TRACK GUIDE

• Turn 1 (Peraltada entry replacement/first chicane): Late braking here rewards trail-braking deep with high coast diff lock (0.6) to rotate the nose without snap-oversteer; altitude means your braking marker should be slightly earlier than muscle memory from sea-level tracks.
• Esses (Turns 2-3): Commit to a smooth but fast direction change — minimum steering correction, let the stiffer rear ARB handle load transfer; time is won by carrying speed through here, not by late apex alone.
• Turn 4/5 (hairpin): Heavy, low-speed braking zone — maximize front brake torque and get on power early but progressively (TC2 at 1 will cut slightly to prevent wheelspin at low grip/high altitude).
• Foro Sol Stadium Section (final corners): This is where lap time is made or lost — late apex, aggressive rotation on entry, then full attack on the exit kerbs; the 720S's strong mechanical grip and coast diff setting lets you carry more min-speed than rivals.
• Final corner onto front straight: Prioritize exit traction over entry speed — power percentage (0.35) is tuned low to allow max corner exit acceleration without wheelspin at altitude, critical for straight-line speed down the front stretch.

TYRES

• Compound: Dry (Medium) — Front 27.8 PSI, Rear 27.3 PSI cold (race start, Autódromo's altitude thins real air density but tyre model unaffected — compensate slightly up from base 27.5F/27.0R due to high-energy braking zones and track temp)
• Optimal operating window: 80–95°C across all four tyres for peak grip; above 105°C expect accelerated thermal degradation, below 70°C grip falls off sharply
• Blanket temp (if used in session): 70°C front/rear

ELECTRONICS

• TC1: 6
• TC2: 3
• ABS: 5
• Engine Braking / Brake Magic: Medium-High (3 of 5) — helps rotation on entry without destabilising rear on Mexico's long braking zones
• Brake Bias: 54.5% front (base), adjustable -1% as fuel burns

DAMPERS

AERO

• Front Wing: 4 (of 5 — max per car context recommendation for rear stability)
• Rear Wing: 8 (of 10) — high downforce to combat altitude-reduced air density and stabilise rear under heavy braking
• Downforce Level: High
• Brake Ducts: Front 4 / Rear 3 (manage brake temp given altitude heat soak and long straights)

KEY SETUP NOTE

• Mexico City sits at ~2,240m altitude — reduced air density means less effective downforce and less effective engine cooling; run wing levels higher than you would at sea level, and monitor brake/engine temps closely as straight-line speeds will be deceptively high into Turn 1 and the Foro Sol stadium section.

TRACK GUIDE

• Turn 1 is the biggest overtaking and defending zone — brake later than feels safe on entry from the pit straight, but respect reduced aero grip at this altitude; trail-brake to rotate the 720S's nose
• Esses (Turns 7-11) reward a stable rear — use high coast lock to avoid snap oversteer on direction changes, sacrifice outright mid-corner speed for a clean exit onto the back straight
• Foro Sol stadium section (Turns 15-17) is where lap time is won — late, confident brake into 16, then carry momentum through the tightening final corner; track-limits enforcement is strict here
• Traction out of the final corner onto the main straight is critical — get the power down early with TC2 at 3 to avoid wheelspin, as the full straight length amplifies any exit mistake
• Manage tyre deg by avoiding excessive kerb use at Turns 4 and 12 — the altitude already stresses tyre carcass temps, aggressive kerb strikes accelerate right-rear degradation significantly over a race stint
