DAMPERS

AERO

• Front Wing: 6 (of 10)
• Rear Wing: 8 (of 10)
• Downforce Level: High — max stability commitment through Piratella, Alta, Rivazza
• Brake Ducts: F: 4 / R: 3

KEY SETUP NOTE

• Run more rear wing than feels natural (8) paired with a strong coast diff lock (0.65) — this is what lets you commit flat through Variante Alta and trail-brake deep into Tosa/Rivazza without the rear stepping out; the McLaren's short wheelbase punishes any hint of rear instability on this bumpy, kerb-heavy layout.

TRACK GUIDE

• Tamburello: stay full commitment over the kerbs — stiffer rear ARB keeps platform flat, don't lift mid-kerb.
• Tosa hairpin: brake very late, rotate hard on entry, get on power early but progressively — coast diff lock prevents snap oversteer on corner exit onto the back straight.
• Piratella: trail-brake to load the front, the extra front wing (6) keeps nose planted on the uphill braking pitch.
• Acque Minerali: soften your inputs through the compression — let the dampers absorb it, avoid mid-corner corrections that cost rotation.
• Rivazza 1&2: this is where the lap is won — sacrifice a fraction of entry speed for a clean, full-throttle exit onto the pit straight; carrying speed here matters more than the final chicane.
