Ferrari 458 GT2

TYRES

• Compound: Slick Medium (M). Recorded lap ran M at 25 °C air / 36 °C track, so no change; Soft not taken because it overheats over a single push lap with no warm-up.
• Front pressure: 19.5 PSI cold (FL/FR) → hot target ~23.0 PSI
• Rear pressure: 21.5 PSI cold (RL/RR) → hot target ~24.5 PSI
• Recorded hot reference: 23.5 / 22.3 / 25.2 / 24.0 PSI. Targets sit at the middle of that band, slightly lower on the fronts for a better contact patch.
• Tyre blankets: not a car property in AC, so don't assume them. If the session has them off, lap 1 is the warm-up lap and the out-lap must put heat into the fronts.
• Alignment (in-car units):
• Camber F / R: -3.4° / -2.2°
• Toe F / R: +0.00° / +0.15° (rear toe-in for Parabolica and Lesmo stability; front kept at zero for sharp chicane turn-in)
• Caster: not adjustable on this car, so no value is given.

ELECTRONICS

• TC: not adjustable, no value. ABS: not adjustable, no value. Brake magic / engine braking: not available. ERS: not applicable (no hybrid). Brake bias is set in the SUSPENSION block below and is adjustable in-cockpit.

SUSPENSION

• // FRONT
• Ride Height: 58 mm
• Wheel Rate FL / FR: 120,000 N/m / 120,000 N/m
• ARB: 80,000 N/m
• Brake Torque Multiplier: 100%
• Brake Bias: 66.0% (matches the recorded lap; one-click adjustments in the cockpit if T1 locks fronts)
• // REAR
• Ride Height: 64 mm
• Wheel Rate RL / RR: 105,000 N/m / 105,000 N/m
• ARB: 60,000 N/m
• Diff Preload: 30 Nm
• Diff Coast: 0.4
• Diff Power: 0.3 (open enough to keep the car stable on exit; lock on kerbs and the Parabolica exit is managed with throttle)

DAMPERS

• Fast damping stays softer than slow so the car rides the Rettifilo, Roggia and Ascari kerbs without skipping.

AERO

• Front wing/splitter: 1
• Rear wing: 1 (minimum drag; Monza is won on the straights)
• Brake ducts: not adjustable on this car, so no value is given.
• Note: the 458 GT2 exposes aero as integer steps. If the car's setup screen offers fewer steps than quoted, take the lowest available for both ends.

KEY SETUP NOTE

• Monza's lap time comes from top speed and the Parabolica exit, so run minimum wing and resist the urge to add rear wing for stability. Rear stability comes instead from the rear toe-in, the 0.4 coast lock and the stiffer front ARB split, which gives the sharp front-end rotation the three chicanes demand without the drag.

TRACK GUIDE

• Rettifilo (T1/2): brake from ~330 km/h at the 100 m board, trail the brake to the apex and straddle the inside kerb. Do not overuse the exit kerb. Loss of traction here costs time all the way down to Curva Grande.
• Curva Grande: flat in qualifying trim. Stay wide on entry, kiss the apex and let the car drift to the exit kerb without lifting.
• Roggia (T4/5): brake in a straight line, turn in late, and use the kerb on the left-right transition. Square the exit so the throttle goes on early for the run to Lesmo.
• Lesmo 1 and 2: carry speed into Lesmo 1 with a slight trail brake, then be patient at Lesmo 2 where understeer builds. Prioritise exit speed over entry as it feeds the long back straight.
• Ascari and Parabolica: take Ascari on the kerbs with a smooth, flat line. At the Parabolica, brake early and straight, turn in late and apply throttle progressively past the apex. This corner is the lap and is worth more than any other single tenth.
