BMW M4 GT3 Evo

TYRES

• Compound: Slick — Dry (Medium)
• Front Pressure: 26.5 PSI (cold, single-lap attack — accounts for quick heat build on out-lap)
• Rear Pressure: 26.2 PSI (cold)
• Optimal Operating Temp: 85–95°C (peak grip window for GT3 slick compound)
• Camber Front: -3.8°
• Camber Rear: -2.6°
• Toe Front: -0.05° (slight toe-out for turn-in bite)
• Toe Rear: +0.15° (toe-in for high-speed stability at 100R/200R)
• No tyre blankets (not available in AC Evo).

ELECTRONICS

• TC1: 3 (minimum needed to catch T14/Netz Kurve traction spikes without killing exit drive)
• TC2: 2
• ABS: 4 (supports maximum-attack T1 braking stability without losing outright stopping power)
• Engine Braking / Brake Magic: Medium-High (setting 6/10) — aids rotation into hairpins
• Brake Bias: 56.5% front (see SUSPENSION)

DAMPERS

AERO

• Front Splitter: 2 clicks (minimum viable — priority on low drag for 1.475km main straight)
• Rear Wing: 4/10 (low-medium — balance against low front to avoid snap oversteer at 100R/200R)
• Downforce Level: Low-Medium bias, optimized for straight-line speed with just enough rear to trust 100R commitment
• Brake Ducts: Front 2 / Rear 3 (single lap — no thermal concern, keep discs in operating window only)

KEY SETUP NOTE

• Fuji GP is a power-track — the 1.475km main straight punishes drag mercilessly, so this setup trims wing aggressively; the trade-off is you must manage rear stability yourself through 100R and 200R with steering inputs and trail-braking discipline rather than relying on aero to bail you out.

TRACK GUIDE

• T1 hairpin: brake as late as physically possible from 300km/h+, trail-brake deep to rotate the M4 GT3 on entry — carrying too much speed here costs the entire run to T2.
• 100R: commit with a stable rear — do NOT lift mid-corner; the low-drag rear wing setup means the car will get light, so smooth thro
