DAMPERS

AERO

• Front Splitter: 8 (max attack setting)
• Rear Wing: 9 (near-max downforce, Hungaroring is low-speed-dominant and downforce-hungry)
• Downforce Level: Maximum within legal GT3 range — no straight-line compromise needed
• Brake Ducts: Front 5 / Rear 4 (single lap, no thermal concern, keep tight for aero)

KEY SETUP NOTE

• Hungaroring punishes any rear instability through the T3–T6 valley and rewards traction out of T11 — run slightly softer rear ARB and more rear-biased diff coast to rotate confidently into the valley while retaining drive grip for the long run to the final chicane; max downforce is "free" here since there's no real top-speed penalty.

TRACK GUIDE

• T1: Late, aggressive trail-brake entry — car should rotate hard on turn-in to set up the short chute into T2.
• T3–T6 valley: Commit to a single flowing line — do not lift mid-sequence; rear must stay planted on direction changes, trust the diff and rear ARB softness here.
• T11 hairpin: This is the lap-defining corner — sacrifice ultimate min-speed for a clean, early, straight-line exit since it feeds the longest acceleration zone on track.
• T14 chicane: Treat as exit-priority — a slightly wider, smoother entry preserves speed onto the pit straight; don't scrub exit speed for a sharper apex.
• Overall: lap time lives in minimizing speed loss through the valley (T3-T9) and maximizing traction at T11 — these two sections separate hot laps from average ones.

THEORETICAL BEST LAP

• 1:48.300 — optimal sector composite, dry, max-attack single lap, AMS2 physics baseline.
