AERO
- Front Splitter: 3 (of 6 clicks)
- Rear Wing: 5 (of 8 — Nordschleife/GP combo demands high stability for Nordschleife sections while keeping straight-line speed on GP back straight)
- Downforce Level: Medium-High
- Brake Ducts: Front 3 / Rear 2 (endurance heat management)
KEY SETUP NOTE
- The Nürburgring 24H combined layout (GP + Nordschleife) punishes unstable rear platforms through the high-speed Nordschleife kinks — slightly higher rear ride height and firmer rear ARB than a pure GP setup keeps the M4 planted without killing the mechanical traction needed for Ford-Kurve and the Dunlop hairpin exits. Prioritize a diff power lock of 0.65 (not higher) to prevent rear tyre deg spiking over a full race stint.
TRACK GUIDE
- Brake hard and late into Yokohama-S (T1), but carry rotation with trail-braking — the M4 GT3's front end responds well to aggressive turn-in here.
- Through the Nordschleife's high-speed esses (Hocheichen, Quiddelbacher Höhe), stay smooth on the wheel — mid-corner ARB stiffness rewards commitment but punishes sudden inputs.
- Traction out of the Dunlop hairpin and Ford-Kurve is where lap time is won — get the car rotated early and get on power progressively to avoid overloading the rear tyres over a long stint.
- Veedol chicane: sacrifice a fraction of entry speed for a clean exit
