BMW M4 GT3 Evo

TYRES

• Compound: Dry (Medium)
• Front Pressure: 27.3 PSI
• Rear Pressure: 27.0 PSI
• No tyre blankets (AC Evo — cold set on grid, manage warm-up over lap 1)
• Optimal operating temp: 85–95°C (peak grip window, avoid exceeding 105°C in race stints)

ELECTRONICS

• TC2: 3
• ABS: 4
• Engine Braking / Brake Magic: Medium (setting 3 of 6)
• Brake Bias: 54.5% front (adjustable -1% for endurance stint as fuel burns off)

DAMPERS

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
