DAMPERS

AERO

• Front Wing: 1 (minimum, low drag)
• Rear Wing: 4 (Monza-specific low-medium, balanced against GT3R's naturally high rear wing efficiency)
• Downforce Level: Low-drag Monza trim
• Brake Ducts: Front 1 / Rear 1 (cold lap, single hot lap — minimal cooling needed)

KEY SETUP NOTE

• On a single qualifying lap, the 911 GT3 R's rear-engine polar inertia is an asset at Parabolica and Lesmo exits but a liability under the Rettifilo/Roggia chicane braking — run slightly higher rear ride height (62mm) than race setup to prevent snap rotation on trail-braking into T1 and T4, while keeping front end sharp (55mm, soft-ish front ARB) to maximize chicane rotation since tyre wear and long-run stability don't matter.

TRACK GUIDE

• T1/2 (Rettifilo): Brake as late as physically possible from ~335 km/h — trail brake deep, use the GT3R's strong front end to rotate hard on entry, sacrifice a perfect line for min speed loss; attack the inside kerb aggressively on exit.
• T3 (Curva Grande): Flat or near-flat in top gear — commit fully, this is a load-bearing corner for the rear tyres, trust the low-drag aero.
• T4/5 (Roggia): Second heavy braking zone — late brake, slight lift-and-rotate technique works better than pure trail-brake given rear weight bias; get back to power early for the run to Lesmo.
• Lesmo 1/2: Sacrif
