DAMPERS

AERO

• No adjustable wings on GT40 (fixed bodywork). No brake duct adjustment. Downforce level fixed — car relies on low drag for top speed down Monza's straights.

KEY SETUP NOTE

• The GT40 has a live-axle-like rear stiffness character and narrow tyre contact patch by modern standards — at Monza the priority is maximizing front-end bite into the two chicanes without destabilizing the rear over the Ascari kerbs; running slightly stiffer front ARB than rear and softer rear compression helps rotate the car on entry while keeping the rear planted for Parabolica exit traction.

TRACK GUIDE

• Variante del Rettifilo: Brake hard but progressively — the GT40's drum-era-style brake feel (even with modern discs modeled) needs a firm, early squeeze rather than a stab; trail brake lightly into the first apex to rotate the nose.
• Curva Grande: Taken near-flat but respect the live rear axle feel — smooth steering input, avoid sudden direction change, let the car ride the camber.
• Roggia chicane: Similar to T1/2 — this car's long wheelbase makes it stable under straight-line braking but resistant to rotation, so brake slightly earlier and use curb minimally to avoid unsettling the rear.
• Lesmo 1 & 2: Focus on patient throttle application — the GT40's torque-heavy V8 will snap the rear loose if power is applied before the car is rotated; prioritize a clean, late apex.
• Ascari chicane: Keep inputs smooth over the kerbs — this car does not like aggressive kerb-riding due to limited wheel travel; a flatter, more measured line beats outright aggression here.
• Parabolica: This is where lap time is won — get on the power early and progressively, use the GT40's torque to carry a long, building exit speed onto the front straight.
