Porsche 911 (992) GT3 Cup — Base

TYRES

• Compound: Slick Soft (Cup spec control tyre)
• Front Pressure: 27.5 PSI
• Rear Pressure: 27.0 PSI
• No tyre blankets in AC Evo — tyres must be warmed via out-lap weaving and brake/throttle modulation
• Optimal operating temperature: 85–95°C core for peak grip window

ELECTRONICS

• TC: 3 (aggressive single-lap rotation, minimal power cut)
• ABS: 5
• Engine Braking / Brake Magic: Medium-Low (reduce rear locking into Schumacher-S and T1)
• Brake Bias: 68% front (qualifying bias, see below)

SUSPENSION

• // FRONT
• Ride Height: 55 mm
• Wheel Rate FL / FR: 115000 N/m / 115000 N/m
• ARB: 22 N/m (soft-mid, promotes rotation on turn-in)
• Brake Torque Multiplier: 100%
• Brake Bias: 68%
• // REAR
• Ride Height: 60 mm
• Wheel Rate RL / RR: 130000 N/m / 130000 N/m
• ARB: 28 N/m
• Diff Preload: 40 Nm
• Diff Coast: 0.7
• Diff Power: 0.5

DAMPERS

AERO

• Front Splitter: minimum legal clearance setting (lowest, max sensitivity)
• Rear Wing: 5 (of typical 1–6 Cup wing range) — max downforce for Nordschleife-style combined fast/technical sections
• Downforce Level: High (qualifying-biased, straight-line speed secondary to rotation/stability)
• Brake Ducts: N/A (fixed on Cup spec)

KEY SETUP NOTE

• With tyre wear irrelevant and only one lap on cold-ish tyres, run the front ARB slightly softer than race baseline to force early rotation on turn-in — this 992 Cup car understeers on entry when pushed to qualifying limits, and the GT-style high coast lock keeps the rear planted enough to compensate without snap oversteer.

TRACK GUIDE

• Veedol-Schikane region (start/finish area blending into T-Fahrten) rewards carrying maximum minimum-speed through the chicane — sacrifice nothing, use full kerb on exit.
• Hocheichen and the run to Flugplatz: commit full throttle early, the long rear wheelbase and planted rear diff forgive slight oversteer on exit.
• Adenauer Forst (double-apex right-left): late, aggressive trail-braking on entry rotates the car — trust the front end with 68% bias.
• Bergwerk hairpin: this is the biggest traction zone on the lap — get on power as early as possible even if it means a wider exit line, Cup car rear grip rewards early throttle.
• Pflanzgarten/Stefan-Bellof-S (if included in T-Fahrten layout run): compression kerbs unsettle the car — stay committed, soft-ish ARB front helps absorb without lifting.
