McLaren 720S GT3 Evo

TYRES

• Slick (Dry), Front: 1.78 bar, Rear: 1.72 bar — cold set pressures accounting for aggressive stint heat build. Tyre blanket temp: 80°C. Optimal operating window for max grip: 85–95°C (front and rear).

ELECTRONICS

• TC1: 6
• TC2: 3
• ABS: 5
• Brake Pressure: 97%
• Brake Bias: F: 54% / R: 46%

DRIVETRAIN

• Fuel Map: Map 2 — balanced power delivery with slightly leaner mixture for race-length fuel saving without sacrificing drivability out of T5/T12.
• Gear Ratios:
• 1st: 2.98
• 2nd: 2.35
• 3rd: 1.93
• 4th: 1.64
• 5th: 1.42
• 6th: 1.25
• Final Drive: 3.44 — tuned for Road America's long back straight top speed while keeping 1st gear sharp enough for the Carousel/Kink exits.

SUSPENSION

• // FRONT
• Ride Height: 55 mm
• Wheel Rate FL / FR: 145000 N/m / 145000 N/m
• ARB: 120000 N/m
• Brake Torque Multiplier: 97%
• Brake Bias: 54%
• // REAR
• Ride Height: 58 mm
• Wheel Rate RL / RR: 165000 N/m / 165000 N/m
• ARB: 95000 N/m
• Diff Preload: 55 Nm
• Diff Coast: 0.65
• Diff Power: 0.35

DAMPERS

AERO

• Front Splitter: 4 (of available adjustment range, aggressive)
• Rear Wing: 8 (high-downforce setting — Road America rewards stability through Kink and Carousel over top-speed on back straight)
• Downforce Level: High — biased for rear stability on throttle application
• Brake Ducts: Front 4 / Rear 3 — moderate cooling, enough to prevent brake fade on heavy stops into Turn 5 and Turn 8

KEY SETUP NOTE

• Road America's long straights and heavy braking zones (T5, T8, T12 Canada Corner) punish a car that isn't stable under trail-braking — run slightly higher coast lock (0.65) and stiffer rear spring than base ACC setups to control the 720S's natural snap on throttle release, especially critical through the fast Kink (T12) and the uphill Carousel exit.

TRACK GUIDE

• Turn 1: Late braking into the fast right-hander — trail brake deep but respect the car's rotation tendency; carrying too much entry speed unsettles the rear on the slightly cambered surface.
• Turn 5 (Kink): Flat-out commitment is lap time — any lift here costs multiple tenths; rear stability setup pays off directly.
• Turn 6-7 (Carousel): Long, sustained-radius corner — patience on throttle application is key; rolling speed through the middle matters more than an aggressive apex.
• Turn 8: Heavy braking zone after long straight — this is where races are won/lost on brake stability; don't trail brake too aggressively or the rear will step out under the Evo's sharp initial bite.
• Turn 12-14 (Canada Corner complex): Final traction zone onto the front straight — prioritize exit speed over mid-corner speed; a clean, early throttle application here is worth more than anywhere else on the lap.
