McLaren 720S GT3 Evo

TYRES

• Slick (dry, single-lap qualifying compound), Front 27.0 PSI cold, Rear 26.5 PSI cold — targets ~27–28 PSI hot front/rear once up to temp. Optimal slick operating window: 80–95°C, peak grip around 85–90°C. No tyre blankets assumed — first flying lap must manage cold-tyre grip through Paddock Hill.

ELECTRONICS

• TC1: 4 (low, max attack, Brands has good mechanical grip zones but aggressive rotation needs some slip allowed)
• TC2 (slip reduction on corner exit): 3
• ABS: 5
• Brake Bias: 54.5% front (single-lap, no tyre degradation concern — biased forward for late braking confidence into Paddock and Druids)

SUSPENSION

• // FRONT

• Diff Power: 0.35

DAMPERS

AERO

• Front Splitter: 4 (of typical 0–10 range) — aggressive front load for Paddock/Druids turn-in
• Rear Wing: 7 (of typical 0–10 range) — maximise rear stability for Surtees, Westfield, Clearways
• Brake Ducts: Front 4 / Rear 3 (single lap — minimal cooling need, prioritize aero tightness over ducting drag)

KEY SETUP NOTE

• Brands Hatch's blend of a heavy braking compression at Paddock and a flat-out, rear-loaded exit at Clearways means the 720S GT3 Evo must run noticeably more rear wing than the straight-line speed penalty suggests — the lap is won by trusting rear grip at Westfield/Clearways and carrying speed onto the pit straight, not by outright top speed.

TRACK GUIDE

• Paddock Hill (T1): Brake late and hard on the downhill compression — trust the high front aero load, but delay full brake release to let the nose settle before turn-in; apex late to set up Druids approach.
• Druids (T3): This is the lap's biggest traction zone — get on power progressively from apex, let the strong coast-lock diff settle rotation, straight-line the exit kerb to maximize drive onto Graham Hill.
• Surtees/Westfield (T8/T11): Taken at high speed with heavy lateral rear load — commit early, trust the stiffer rear spring/ARB setup to resist snap, stay full or near-full throttle through Westfield.
• Dingle Dell/Sheene chicane (T12/13): Use the kerbs aggressively but keep ride height stable — unsettling the car here costs time into Stirlings.
• Clark Curve/Clearways (T16): The lap-defining corner — carry maximum minimum-speed through this long sweeper onto the pit straight; exit speed here is worth more than anywhere else on track.
