DAMPERS

AERO

• Fixed aero package (G40 production bodywork, no adjustable wings) — stock front splitter and rear lip only, no brake duct adjustment available

KEY SETUP NOTE

• The G40's low power means every traction-zone compromise at Ferradura and Junção costs more than any straight-line speed gained from a stiffer diff — run the softer power lockup setting here to maximize drive onto both straights even if it costs a touch of mid-corner stability.

TRACK GUIDE

• Senna S: brake hard but progressively — the G40's weight transfer is slow, so trail off brake pressure smoothly through the S rather than trail-braking aggressively like in a faster car.
• Ferradura: rotate the car early on entry since the G40 has modest grip; prioritize a clean, early apex to get full throttle before the exit kerb for the run to the back straight.
• Mergulho: the compression here will unsettle a soft-sprung low-power car — stay smooth on brake release, trust the chassis, don't lift mid-compression.
• Junção: this is the lap-defining corner — sacrifice a slightly wider entry line for a straighter exit, since the full final-sector climb punishes any wheelspin brutally in this low-torque car.
• Arquibancadas: carry as much mid-corner speed as possible rather than relying on exit traction — the G40 benefits more from minimum-speed carry than late power application here.
