DAMPERS

AERO

• Front wing/splitter: 3 clicks
• Rear wing: 7 clicks (the Cup runs less rear wing than the GT3 R, so use a high setting to hold Skyline and The Chase braking stability)
• Downforce level: medium-high; trade a few km/h on Conrod for rear stability on the descent
• Brake ducts: N/A (use the minimum cooling opening for a single lap)

KEY SETUP NOTE

• Bathurst punishes a loose rear more than any other circuit. Skyline, The Dipper and Forrest's Elbow all load the rear while the car is light or committed. Keep the rear ride height at 76 mm and the rear ARB soft (45000 N/m) so the 992's rear-engine weight stays compliant instead of snapping on the crest. Use the diff preload and wing for stability, not the ARB.

TRACK GUIDE

• Hell Corner / Mountain Straight: Brake late but straighten the car early. Apply throttle progressively and avoid a TC intervention, which is slow up the long climb.
• The Cutting to Skyline: Hit the tight S precisely, set the car for the crest and stay flat over Skyline. Keep the steering input small as the car goes light, and avoid any lift or mid-crest steering correction.
• The Dipper to Forrest's Elbow: Brake in a straight line before the blind descent, trail-brake to rotate and commit through the steep downhill. Use the rear compliance and keep the car tidy in Forrest's.
• Murray's Corner: Use a late apex and be patient on throttle. This is the key traction zone, and the exit speed carries the whole length of Conrod.
• The Chase: Brake in a straight line from top speed with maximum pressure, then clip the kerbs and rotate aggressively. Prioritise a clean exit onto the following sections and carry momentum over the mountain through McPhillamy.
