DAMPERS

AERO

• Front splitter: 2 (of 5 clicks) — keep drag low for Döttinger Höhe
• Rear wing: 4 (of 6) — balance for Karussell/Fuchsröhre stability without killing top speed
• Downforce level: Medium — biased toward low-drag for long straight
• Brake ducts: Front 2 / Rear 2 (minimal — single lap, no overheating concern)

KEY SETUP NOTE

• The Nordschleife's combination of Döttinger Höhe top speed and Fuchsröhre/Flugplatz high-speed compression demands a rear ride height and spring rate high enough to avoid bottoming at compression without sacrificing the planted rear feel needed to trust the throttle flat-out at Kesselchen — slightly firmer rear ARB than usual M4 GT3 setups helps rotate through Adenauer without destabilizing the rear over Brünnchen's bumps.

TRACK GUIDE

• Flugplatz/Schwedenkreuz: commit flat-out, trust the aero — any lift costs more than it saves; car will go light over the crest, stay smooth on wheel input.
• Fuchsröhre: brake lightly before compression, let the car load up, do not trail-brake deep into the compression — unload fronts progressively into the fast right.
• Adenauer Forst: this is where you make time with late, aggressive trail-braking and early rotation — use high TC-disengagement confidence on corner exit for traction onto the next straight.
• Karussell: take the banking on the inside, let the banked kerb carry speed — slightly lift mid-ent
