KEY SETUP NOTE

• Montreal's long straights into heavy braking zones (T1, T10, hairpin) demand a rear-biased mechanical platform with strong front brake bite — the slightly softer rear ARB and power diff setting help rotate the car hard off the hairpin and chicane exits without snap oversteer, critical for aggressive late-apex driving over race stint tyre wear.

TRACK GUIDE

• Turn 1: Brake extremely late off the start/finish straight — trail brake deep to rotate; this is the primary overtaking zone, commit to inside line
• Turn 10 Hairpin: Hardest braking zone on track — use the full width, aggressive trail-brake rotation, prioritize exit traction over entry speed for the run to the chicane
• Casino Chicane (Turns 13-14): Attack curbs hard but stay smooth on throttle — the Cadillac's long wheelbase punishes excessive kerb strikes with rear instability
• Wall of Champions (final corner): Respect the wall on exit — a conservative but fast exit line beats a spectacular risk here, as it sets up the full straight
• Tyre management: Rear tyres degrade fastest under hard throttle application exiting hairpin/chicane — modulate traction control-assisted throttle in final third of stint to preserve rear grip for late-race pace
