DAMPERS

AERO

• Front Splitter: Level 3
• Rear Wing: Level 6 (compromise: higher than typical GT3 for rear stability at Flugplatz and Kesselchen, trimmed from max to protect Döttinger Höhe top speed)
• Downforce Level: Medium-High
• Brake Ducts: Front 3 / Rear 2 (single-lap, hot brakes fine, ducts open enough to avoid fade over the 20.8 km)

KEY SETUP NOTE

• The 992's rear-engine pendulum effect is the limiting factor over the Nordschleife's crests: the stiff rear ARB (78000 N/m), the high coast diff lock (0.7) and the high rear wing keep the car planted over Flugplatz and Kesselchen where the rear goes light, while the deliberately compliant dampers and 74 mm rear ride height absorb the Brünnchen bumps without bottoming and snapping the rear on exit.

TRACK GUIDE

• Hatzenbach to Flugplatz: Stay tight to the left on Hatzenbach, use the kerbs aggressively, and take Flugplatz flat. Keep the wheel dead straight over the crest and let the high rear wing keep the tail planted.
• Fuchsröhre to Adenauer Forst: Brake late for Adenauer Forst, bleeding off the brake at turn-in and carrying a little trail brake to rotate the rear-engine car. Wait for the car to settle before getting on the power, since the traction will be strong.
• Karussell: Take the banked inside line, staying on the concrete with the inside kerb. Stay smooth on the throttle on exit and avoid over-rotating on the banking.
• Brünnchen to Döttinger Höhe: Stay flat over the Brünnchen bumps, trusting the compliant dampers and the rear wing to keep the car stable, then build maximum exit speed onto Döttinger Höhe because the long straight multiplies any gain.
• Lap time is won in the fast, flat sections (Flugplatz, Schwedenkreuz, Bergwerk, Kesselchen) by committing fully and trusting the rear, and lost in the slow Adenauer Forst and Karussell sections by over-driving the entry and wasting exit speed.
