Porsche 992 GT3 Cup

TYRES

• Compound: Pirelli Cup Slick (Dry)
• Front: 27.2 PSI cold
• Rear: 26.7 PSI cold
• Tyre blanket: not applicable (ACC has no blanket setting)
• Optimal operating temperature: 85–95°C (peak grip window; target 88–92°C core temp)
• Race note: Cold pressures set 0.2 PSI above the standard 27.0/26.5 start to hold pressures down over a long stint. Target hot pressures of 29.5–30.5 PSI front, 29.0–30.0 PSI rear.

ELECTRONICS

• TC1: 3
• TC2 (TC cut): 2
• ABS: 4
• Engine map: 1 (Cup car has a fixed ECU, use default)
• Brake bias: 57.5%
• Note: The Cup car has no ERS or brake magic. Setting TC1 low gives max rotation for aggressive trail braking while still protecting the rear on the Druids and Clearways exits.

SUSPENSION

• // FRONT
• Ride Height: 54 mm
• Wheel Rate FL / FR: 130,000 N/m / 130,000 N/m
• ARB: 48,000 N/m
• Brake Torque Multiplier: 100%
• Brake Bias: 57.5%
• // REAR
• Ride Height: 66 mm
• Wheel Rate RL / RR: 145,000 N/m / 145,000 N/m
• ARB: 60,000 N/m
• Diff Preload: 95 Nm
• Diff Coast: 0.7
• Diff Power: 0.4

DAMPERS

AERO

• Front splitter: 3
• Rear wing: 7
• Downforce level: medium-high (rear-biased for stability in Clearways and Paddock Hill Bend)
• Brake ducts: Front 3 / Rear 2 (adequate cooling for the heavy Paddock Hill and Druids stops, with minimal drag penalty on the short lap)

KEY SETUP NOTE

• The rear ride height is the setup's most sensitive variable. At 66 mm it keeps the rear platform stable over the Paddock Hill compression and the Clearways kerbs, but dropping below 63 mm makes the 992's rear-engine inertia snap on throttle at Druids exit. High coast lock (0.7) stabilises the car on the downhill Paddock Hill entry while still allowing aggressive trail-braking rotation.

TRACK GUIDE

• Paddock Hill Bend: Brake late at the crest but stay on the pedal into the compression, and trail brake deep to rotate the car at the apex. Release gradually, as the heavy rear will push wide if you rush the throttle.
• Druids: Prioritise a straight exit over a late apex. Brake hard, rotate with a short trail, then pick up the throttle progressively. Wheelspin here costs time all the way down Cooper Straight.
• Graham Hill Bend: Trail brake downhill to load the front and rotate the nose. Keep a smooth, late throttle application to avoid rear instability.
• McLaren Bend (T7): Hold a steady, committed lateral load through the sweeping right. Use the kerb sparingly on exit so the car stays settled for Clearways.
• Clearways / Clark Curve: Exit speed is critical, because it feeds the long run to the line. Use the full track width, apply throttle early and smoothly, and avoid TC intervention. This is where the most lap time is won or lost.
