Ford Mustang GT3

TYRES

• Wet compound, Front 25.5 PSI, Rear 25.0 PSI. Blanket temp 70°C. Optimal operating window for Wet compound: 55–70°C (tread surface) for maximum grip — avoid overheating above 80°C which causes rapid graining and deg.

ELECTRONICS

• TC1: 6, TC2: 3, ABS: 6, Engine Map: 3 (conservative fuel/power for wet traction), Brake Bias: 54%, Brake Driver (pedal sensitivity): 65%

SUSPENSION

• // FRONT
• Ride Height: 75mm
• Wheel Rate FL / FR: 110000 N/m / 110000 N/m
• ARB: 4
• Brake Torque Multiplier: 85%
• Brake Bias: 54%
• // REAR
• Ride Height: 85mm
• Wheel Rate RL / RR: 105000 N/m / 105000 N/m
• ARB: 3
• Diff Preload: 45 Nm
• Diff Coast: 0.3
• Diff Power: 0.5

DAMPERS

AERO

• Front Splitter: 3, Rear Wing: 6, Brake Ducts Front: 4, Brake Ducts Rear: 3 (less cooling needed in wet, prioritize drag reduction and warm-up)

KEY SETUP NOTE

• In wet conditions the Mustang's heavy front end and torquey V8 combine dangerously under power — soften power diff (0.5) and keep rear ARB low (3) to prevent snap oversteer on Raidillon exit and Blanchimont, where a twitchy rear at speed is catastrophic in low grip; sacrifice some outright rotation for a planted, predictable rear platform.

TRACK GUIDE

• La Source: brake 10m earlier than dry reference, trail brake gently — wet grip drops fast on turn-in, avoid late aggressive stabs that lock the heavy front.
• Eau Rouge/Raidillon: lift slightly on turn-in if standing water present; full commitment only if track is "wet but drying" — the compression plus wet rear ARB setup should hold, but respect spray and reduced visibility.
• Les Combes: brake in a straight line, wet braking zones punish trail-braking heavy front cars — get all braking done before turn-in to avoid understeer-into-oversteer snap.
• Pouhon: smooth, progressive steering input — any sharp correction unsettles the rear on a long wet load; carry slightly less speed than dry optimal for safety margin.
• Traction zones (Rivage, Bus Stop exit): feed throttle progressively — TC3 setting plus soft power diff should allow early application but abrupt throttle will still spin the rears in standing water.
