Porsche 911 (992) GT3 Cup — Base

TYRES

• Slick (Cup spec), Front: 27.5 PSI, Rear: 27.0 PSI, Camber F: -3.5°, Camber R: -2.8°, Toe F: -0.05° (out), Toe R: +0.10° (in), Optimal operating temp: 85–95°C (peak ~90°C) — no tyre blankets in AC Evo, must build temp on out-lap.

ELECTRONICS

SUSPENSION

• // FRONT
• Ride Height: 55 mm
• Wheel Rate FL / FR: 145000 N/m / 145000 N/m
• ARB: 22 N/m (mid-soft, promote front rotation)
• Brake Torque Multiplier: 100%
• Brake Bias: 56.5%
• // REAR
• Ride Height: 60 mm
• Wheel Rate RL / RR: 160000 N/m / 160000 N/m
• ARB: 30 N/m (stiffer rear to control pendulum effect)
• Diff Preload: 50 Nm
• Diff Coast: 0.65
• Diff Power: 0.45

DAMPERS

AERO

• Front Splitter: 2 (low-mid, balance to stabilise front under Jukskei/Crocodile Kink) | Rear Wing: 6 (near-max, Cup car fixed-wing — stability through high-speed sweeps priority) | Brake Ducts: F 2 / R 2 (irrelevant for wear this session, keep low for minimal drag)

KEY SETUP NOTE

• The 992 Cup car's rear-engine weight bias makes Jukskei Sweep and Crocodile Kink the defining corners — a stiffer rear ARB and slightly higher rear ride height prevent the pendulum snap at high speed, while a softer front ARB/lower front ride height lets you rotate hard into Clubhouse and the Sausage Kink without sacrificing the flat-out sections.

TRACK GUIDE

• T1 Sausage Kink: brake extremely late in a straight line, trail off trail-brake pressure gently through the kink — don't lift mid-kink, the rear will step out under throttle-lift transitions.
• T4 Clubhouse: trail brake deep, rotate the car early using front grip — the Cup car's low front downforce rewards a sharper rotation than GT3 cars.
• T7 Jukskei Sweep: commit flat or near-flat; any lift unsettles the rear — carry max speed, trust the rear ARB stiffness, steer with minimal inputs.
• T11 Sunset/Rietvlei hairpin: this is the lap-defining traction zone — get the car rotated early, get on power progressively to maximise speed down the pit straight.
• T14 Barbecue/Cheetah chicane: brake in a straight line on the elevation change, use slight trail brake to keep weight on the front — aggressive kerb use here costs stability more than it gains rotation in the Cup car.

TYRES

• Compound: Michelin Slick (Cup spec), Front pressure: 27.5 PSI, Rear pressure: 27.0 PSI (hot target 27.5–28.5 PSI all corners), no tyre blankets available in AC Evo — expect 3–4 lap tyre ramp-up window. Optimal operating temperature: 85–95°C.

ELECTRONICS

• TC: 4 (single-level Cup TC, aggressive but stable for hard exit throttle)
• ABS: 5
• Engine Braking / Brake Magic: Medium setting (factory fixed map, no adjustable brake-by-wire — rely on bias instead)
• Brake Bias: 56.5% front (adjustable in-car, start here)

SUSPENSION

• // FRONT
• Ride Height: 60 mm
• Wheel Rate FL / FR: 145000 N/m / 145000 N/m
• ARB: 22 N/m
• Brake Torque Multiplier: 100%
• Brake Bias: 56.5%
• // REAR
• Ride Height: 70 mm
• Wheel Rate RL / RR: 155000 N/m / 155000 N/m
• ARB: 14 N/m
• Diff Preload: 50 Nm
• Diff Coast: 0.7
• Diff Power: 0.35

DAMPERS

AERO

• Front splitter: 2 (fixed-spec Cup car, minimal range)
• Rear wing: 5 (second-from-max, biased toward Jukskei/Crocodile Kink stability)
• Downforce level: Medium-high (Cup car is spec aero, limited adjustment range)
• Brake ducts: Front 3 / Rear 2 (manage brake temp on heavy stops at T1 and T4 without overcooling for race stint)

KEY SETUP NOTE

• The Cup car's rear-engine weight bias and spec aero make the Jukskei Sweep and Crocodile Kink the true setup litmus test — running slightly higher rear ride height (70mm) with firm rear wheel rate and 0.7 coast lock keeps the rear planted on entry and through these flat-out sections, sacrificing a bit of low-speed rotation for the confidence needed to carry speed where lap time is actually won.

TRACK GUIDE

• T1 Sausage Kink: brake hard from top speed but stay straight-line stable — any trail-braking rotation here unsettles the rear on the kink itself; brake in a straight line, release smoothly.
• Jukskei Sweep (T7): flat-out or near-flat commitment corner — build confidence over race stints as tyres go off; aggressive drivers should resist lifting, trust the rear ARB/diff setup to hold the line.
• T11 Sunset hairpin: this is your primary traction zone onto the back straight — get the car rotated early on entry (late braking, trail into apex) so you can unwind the wheel and get full power down earlier than rivals.
• T14 Barbecue chicane: aggressive kerb use here costs time if it unsettles the car for the final hairpin — ride the kerbs with the inside wheels only, keep the car flat for the run to T16.
• T16 final hairpin onto pit straight: this exit defines your entire lap — sacrifice a tenth on entry for a clean, full-power exit; with high coast lock the car should rotate predictably on trail-brake entry here.
