McLaren 720S GT3 Evo

TYRES

• Slick (dry), Front: 27.0 PSI cold, Rear: 26.5 PSI cold
• Optimal operating window: 85–95°C (peak grip around 90°C) — single lap attack, slightly lower cold pressures used to compensate for quicker heat build on an out-lap-to-hot-lap sequence.

ELECTRONICS

• TC1: 5, TC2: 2, ABS: 5
• Engine Braking / Brake Magic: Medium-High (setting 6/10 equivalent — stabilises rear into San Donato/Scarperia without killing rotation)
• Brake Bias: 54.5% front

SUSPENSION

• // FRONT
• Ride Height: 55 mm
• Wheel Rate FL / FR: 145000 N/m / 145000 N/m

• Brake Bias: 54.5%
• // REAR
• Ride Height: 60 mm
• Wheel Rate RL / RR: 165000 N/m / 165000 N/m
• ARB: 95000 N/m
• Diff Preload: 60 Nm
• Diff Coast: 0.6
• Diff Power: 0.3

DAMPERS

AERO

• Front Wing: 4 (of available range, max mechanical balance toward rear stability)
• Rear Wing: 7 (high downforce — committed to Correntaio/Arrabiata stability over straight-line speed)
• Downforce Level: High
• Brake Ducts: Front 3 / Rear 2 (single lap — minimal cooling need, prioritise aero tightness)

KEY SETUP NOTE

• Mugello's high-speed sweepers (Correntaio, Arrabiata 1/2) are flat-out or near-flat commitment corners — the 720S needs maximum rear planted stability here, so running higher rear wing and stiffer rear spring than usual is non-negotiable even at the cost of a touch of straight-line speed; the lap is won by carrying speed through these corners, not by outright top speed on the straight.

TRACK GUIDE

• San Donato (T1): brake as late as possible in a straight line, trail off hard to rotate the nose — heavy traction demand on exit, be smooth with throttle to avoid wheelspin off the hairpin.
• Luco/Poggio Secco (T2/3): committed flat-ish sequence — trust the rear-biased aero setup, minimal steering correction, carry momentum rather than attacking apex.
• Correntaio (T7): near-flat in top gear — this is where the single lap is made or lost; any lift costs multiple tenths, rear stability setup pays off here directly.
• Arrabiata 1 & 2 (T10/11): back-to-back high-load rights — commit on entry, let the car rotate naturally with the high-lock coast diff, avoid mid-corner throttle lift.
• Scarperia (T12) & Bucine (T15): both tight traction zones feeding into straights — prioritize a clean, progressive throttle application over outright rotation to maximize exit speed onto the following straight.
