BMW M4 GT3 Evo

TYRES

• Compound: Medium (dry)
• Front Pressure: 27.3 PSI
• Rear Pressure: 27.0 PSI
• No tyre blankets — build pressure/temp via out-lap weaving and controlled braking before pushing.
• Optimal operating temp window: 85–95°C (core) for peak grip; avoid exceeding 105°C under race-stint deg.

ELECTRONICS

• TC1: 4 (reduced for race-long rear tyre deg management, aggressive but controlled exits)
• TC2 (slip reduction): 3
• ABS: 4
• Engine Braking / Brake Magic: Medium-Low (reduce rear instability under heavy Monza braking zones)
• Brake Bias: 56.5% front (base, adjust -0.5% as fuel burns)

SUSPENSION

• // FRONT
• Ride Height: 55 mm
• Wheel Rate FL / FR: 145000 N/m / 145000 N/m
• ARB: 5500 N/m
• Brake Torque Multiplier: 100%
• Brake Bias: 56.5%
• // REAR
• Ride Height: 58 mm
• Wheel Rate RL / RR: 130000 N/m / 130000 N/m
• ARB: 4200 N/m
• Diff Preload: 50 Nm
• Diff Coast: 0.45
• Diff Power: 0.65

DAMPERS

AERO

• Front Splitter: 2 (minimum practical, reduce drag for straights)
• Rear Wing: 3/10 (low downforce for top speed on long straights, Monza-spec)
• Brake Ducts: Front 3 / Rear 2 (manage temps over race stint without overheating under late-braking style)

KEY SETUP NOTE

• With aggressive late-braking into both chicanes, the low-downforce Monza setup exposes rear stability under trail-braking — the softened engine braking and slightly rear-biased coast diff setting are critical to stop snap-oversteer on corner entry while still allowing the sharp rotation this driving style demands.

TRACK GUIDE

• Variante del Rettifilo (T1/2): Brake as late as possible but in a straight line — trail into the chicane lightly to rotate, using kerbs aggressively on exit without unsettling rear over bumps.
• Curva Grande (T3): Taken near-flat with low wing — commit early, let the aero and chassis balance carry speed; any lift costs significant time.
• Roggia Chicane (T4/5): Similar to T1/2 but faster entry — prioritize stable platform over max rotation to protect rear tyres for the long run to Lesmo.
• Lesmo 1/2: Sacrifice a little entry speed at Lesmo 1 for a cleaner, earlier throttle application through Lesmo 2 — exit speed here feeds the full back straight, worth more than mid-corner speed.
• Ascari Chicane: Needs a flat, stable platform over the kerbs — aggressive kerb riding is fine but avoid excessive ride height loss that could bottom the car; exit speed into Parabolica setup is key.
• Parabolica: The lap-defining corner — patience on initial entry, progressive throttle from apex, and maximizing exit speed is worth more than any other single corner on this layout.
