Toyota GR Yaris Rally1

TYRES

• Compound: Tarmac Soft (single qualifying lap priority — maximum initial grip)
• Front Pressure: 29.5 PSI
• Rear Pressure: 29.0 PSI
• Optimal operating temp: 85–95°C for peak grip window; tyre blankets/formation lap should bring tyres to minimum 70°C before attack lap

ELECTRONICS

• TC: 1 (minimum intervention, max driver control)
• ABS: 2 (slight assistance for late braking stability)
• Engine Braking / Brake Magic: 60%
• Hybrid Deploy: Full aggressive deploy on corner exit and straights, regen scheduled on heavy braking zones only
• Brake Bias: 68% front

SUSPENSION

• // FRONT
• Ride Height: 85 mm
• Wheel Rate FL / FR: 145000 N/m / 145000 N/m
• ARB: 32000 N/m
• Brake Torque Multiplier: 100%
• Brake Bias: 68%
• // REAR
• Ride Height: 90 mm
• Wheel Rate RL / RR: 130000 N/m / 130000 N/m

• Diff Power: 0.6

DAMPERS

AERO

• Front Wing: 28 (high front end bite for fast direction changes)
• Rear Wing: 7 (max downforce setting for tarmac stability at speed)
• Downforce Level: High
• Brake Ducts: 2 (minimal cooling — single lap, no thermal degradation risk)

KEY SETUP NOTE

• Monte Carlo's mixed grip (icy patches, polished tarmac, camber changes) demands a stiffer front/softer rear balance than standard tarmac setup — this promotes early rotation into the tight hairpins (e.g., Turn 1 La Turbie-style corners) without snap oversteer mid-corner, critical when pushing at ten-tenths with no margin for correction.

TRACK GUIDE

• Braking zones: Late, trail-braked entries into hairpins — use the hydraulic handbrake only on the tightest 180° hairpins to rotate without scrubbing speed.
• Corner entry: Commit to aggressive turn-in on fast kinks; the GR Yaris's AWD allows throttle application earlier than expected mid-corner to stabilize rotation.
• Traction zones: Deploy hybrid boost immediately on throttle application out of hairpins and mid-speed corners — this is where Monte Carlo lap time is made.
• Camber/elevation: Watch for shaded, cooler tarmac sections (reduced grip) — adjust braking points slightly earlier there even on a "dry" surface.
• Kerbs: Use kerbs aggressively on fast chicanes to shorten line, but avoid unsettling the car before hairpin entries — stability over kerb-riding near low-speed corners is critical.
