BMW M4 GT3 Evo

TYRES

• Slick, F 27.5 PSI, R 27.0 PSI (hot track temp 42°C — slightly above baseline, small reduction from standard cold spec to avoid overheating on long Nordschleife straights). Optimal operating window: 85–100°C for peak slick grip; qualifying lap should target tyres entering the window within 1–2 corners of leaving the pits.

ELECTRONICS

• TC: 3
• ABS: 2
• Engine Braking: 4 (medium, stability on Fuchsröhre/Kesselchen entries)
• Brake Bias: 53.0% front (shifted slightly rearward from 53.5% to aid rotation on Nordschleife's tighter hairpins, given cooler qualifying fuel load)

SUSPENSION

• // FRONT
• Ride Height: 60 mm
• Wheel Rate FL / FR: 145000 N/m / 145000 N/m
• ARB: 155000 N/m
• Brake Torque Multiplier: 100%
• Brake Bias: 53.0%
• // REAR
• Ride Height: 65 mm
• Wheel Rate RL / RR: 130000 N/m / 130000 N/m
• ARB: 110000 N/m
• Diff Preload: 50 Nm
• Diff Coast: 0.45
• Diff Power: 0.60

DAMPERS

AERO

• Front Splitter: 2 (minimum legal drag setting for Döttinger Höhe top speed)
• Rear Wing: 4 (low-medium downforce, balance for high-speed sections vs Karussell/Adenauer grip)
• Downforce Level: Low-Medium (favor top speed on GP straight + Döttinger Höhe, accept slightly less front grip in Esses)
• Brake Ducts: F 2 / R 2 (minimal, cool track temps not an issue, favor low drag)

KEY SETUP NOTE

• Nordschleife-GP combined lap is dominated by Döttinger Höhe top speed and stability through Fuchsröhre compression — run the lowest downforce you can control through the Karussell and Adenauer-Forst without losing confidence on turn-in, since the time gained on the 2km+ straight dwarfs what's lost in the twisty infield.

TRACK GUIDE

• Fuchsröhre: full commitment flat-out downhill — the compression at the bottom loads the car hard, keep it straight and let the splitter/rear wing balance absorb it, any lift here costs massive time.
• Karussell: use the banking, stay on the inner concrete line, slight trail-brake to rotate, get back to power early for the short straight after.
• Döttinger Höhe: this is where the lap is won — minimize front aero drag, hold the car flat, brake as late as humanly possible into Antoniusbuche.
• GP-Strecke infield (Schumacher-S, Mercedes-Arena): precise, late apex braking rewarded — aggressive trail braking here with the stable BMW platform to carry more min-speed.
• Pflanzgarten/Stefan-Bellof-S: compression and crest combo, be ready for the car to go light — don't lift mid-air, trust the setup and stay committed on the exit kerbs.
