// Hot Lap · Dry
- Note: Porsche 911 GT3 Cup (992) is a spec racing car (one-make cup, ~510hp, fixed aero/mechanical regulations) — values reflect Cup-spec adjustable ranges, narrower than GT3-R.
TYRES
- Slick (Cup spec compound), front pressure 27.5 PSI, rear pressure 27.0 PSI. No tyre blankets in AC Evo — build pressure/temp via out-lap. Optimal operating temperature: 85–95°C for peak grip.
ELECTRONICS
- TC: 3 (aggressive rotation, spec ECU limits range), ABS: 4, Engine Braking: Medium (setting 4/6), Brake Bias: 63.5% front (driver-adjustable in-cockpit, base setup value below)
SUSPENSION
- // FRONT
- Ride Height: 55 mm
- Wheel Rate FL / FR: 132000 N/m / 132000 N/m
- ARB: 18 N/m (spec range, near-max stiffness)
- Brake Torque Multiplier: 100%
- Brake Bias: 63.5%
- // REAR
- Ride Height: 62 mm
- Wheel Rate RL / RR: 128000 N/m / 128000 N/m
- ARB: 12 N/m
- Diff Preload: 40 Nm
- Diff Coast: 0.7
- Diff Power: 0.4

AERO
- Fixed Cup-spec rear wing (no adjustment), front splitter fixed — ride height split is primary aero tool. Brake ducts: 2 (front) / 2 (rear) — minimum needed for one hot lap, reduces drag on Mistral.
KEY SETUP NOTE
- The Cup car's fixed aero means rear ride height control is your only real stability lever at Signes — run it 2mm higher than "ideal" to guarantee the rear stays planted at 260+ km/h, since a snap here costs far more than the tiny drag/rotation penalty elsewhere.
TRACK GUIDE
- T1 (Virage du Pont): Late brake past the 100m board, trail brake deep to rotate the nose — Cup car's strong front grip lets you carry more speed than expected, but stay smooth on throttle application to avoid rear step-out on exit.
- Mistral Straight: Get fully straight and on throttle earliest possible out of the chicane before it — every km/h at the start of Mistral compounds over 1.8km, use minimum brake duct/aero drag.
- Signes: This is the lap-defining corner — commit flat or near-flat, trust the rear ride height setup, do not lift mid-corner even if the car moves around; lifting here costs more time than the small slide.
- Beausset Complex: Brake in a straight line, get the car rotated early on entry to the first apex — this is a traction zone out of the final apex leading to the pit straight, prioritize exit speed over ent
