McLaren 720S GT3 Evo

TYRES

• Dry compound, front 27.3 PSI, rear 26.8 PSI (cold set). Air 24°C / Track 30°C conditions from reference lap are warm-track typical — lowered 0.2 PSI front/rear from base 27.5F/27.0R to compensate for slightly higher track temp pushing pressures up on heat cycle.
• Optimal operating window: 75–95°C across all four tyres for peak grip; qualifying attack lap should target tyres entering the window by Turn 1, so use max blanket temp 80°C front and rear.

KEY SETUP NOTE

• The 720S's mid-engine platform wants a stiffer rear and strong coast-side diff lock to stay planted under Paddock Hill's downhill trail-braking and Druids' tight hairpin exit — without this, the rear will snap during direction changes under heavy braking load transfer; this setup leans into higher rear ARB and coast lock for rotation security while keeping power-side diff looser for cleaner traction out of Druids onto Cooper Straight.

TRACK GUIDE

• Paddock Hill Bend: brake as late as possible on the downhill approach, trail-brake to rotate — the car wants to understeer if you brake too early and straight-line it; commit to a late, firm stab and release progressively.
• Druids: this is where lap time is made or lost — sacrifice entry speed for a clean, early apex and get on power as straight as possible; any wheelspin here costs you the entire Cooper Straight.
• Graham Hill Bend: trail-brake deep into the downhill left, let the rear rotate slightly — don't lift mid-corner or you'll unsettle the platform before Cooper Straight.
• Surtees to Hawthorns/Westfield: a rhythm section — carry momentum, minimize steering correction, treat it as one flowing arc rather than discrete corners.
• Clark Curve (final corner): exit speed is everything onto the front straight — get the car rotated early and be full throttle by the apex; a 2mph gain here compounds for the entire straight.
