DAMPERS

AERO

• Front Splitter: 2 (of 6 clicks, low drag for Döttinger Höhe)
• Rear Wing: 5 (of 8 — higher than typical GT3 for rear stability through Fuchsröhre/Flugplatz/Schwedenkreuz)
• Downforce Level: Medium-high bias rear
• Brake Ducts: Front 2 / Rear 1 (cool enough for single lap, minimal drag)

KEY SETUP NOTE

• The 992 GT3 R's rear-engine polar inertia makes it dangerous on Nordschleife's high-speed crests (Flugplatz, Kesselchen) — running slightly higher rear ride height (70mm) with a stiffer rear ARB than usual GT3 setups keeps the rear planted under load without sacrificing the pendulum-assisted rotation needed in Adenauer Forst and the Karussell; sacrificing a fraction of low-speed agility here buys massive confidence at 240+ km/h sections where lap time is truly made.

TRACK GUIDE

• Flugplatz/Schwedenkreuz: commit flat-out, trust the rear — any lift unsettles the long-travel rear suspension; stay full throttle through the crest
• Fuchsröhre: brake late at compression bottom only if needed — carry max speed, the downhill compression loads the splitter hard, be ready for front push at turn-in
• Adenauer Forst: late, aggressive trail-brake into first apex, use the stiffer coast diff to rotate; get back to power early for the uphill exit
• Karussell: take the banked inside line, unweight slightly on entry, let the banking do the work — avoid excessive steering input, power out early onto the following straight
• Brünnchen bumps: stay loose on the wheel, let the dampers absorb — don't fight the car through the compressions, momentum through here carries to Döttinger Höhe

THEORETICAL BEST LAP

• 7:12.

TYRES

• Compound: Medium slick
• Front Pressure: 27.3 PSI
• Rear Pressure: 26.8 PSI
• Optimal operating temp: 85–95°C (peak grip window; avoid exceeding 105°C under race-stint deg)
• No tyre blankets (AC Evo — cold-start values above apply)
• Camber F/R: -3.5° / -2.0°
• Toe F/R: -0.05° (toe-out) / +0.10° (toe-in)

ELECTRONICS

• TC1: 5 (dry, aggressive but controlled corner exit)
• TC2: 2 (slip-angle shaping on throttle rotation)
• ABS: 5
• Engine Braking: Medium (3/6) — stabilizes rear-engine pendulum into Adenauer/Bergwerk
• Brake Bias: 56.5% front (adjustable -1% for race stint as fuel burns and rear grip increases)

SUSPENSION

• // FRONT
• Ride Height: 60 mm
• Wheel Rate FL / FR: 155000 N/m / 155000 N/m
• ARB: 4 (mid-soft, to aid front turn-in on long compliant sweepers)
• Brake Torque Multiplier: 100%
• Brake Bias: 56.5%
• // REAR
• Ride Height: 70 mm
• Wheel Rate RL / RR: 185000 N/m / 185000 N/m
• ARB: 7 (stiffer rear to control rear-engine pendulum effect)
• Diff Preload: 50 Nm
• Diff Coast: 0.7
• Diff Power: 0.4

DAMPERS

AERO

• Front Splitter: 4 (clicks, moderate — balances against high rear wing)
• Rear Wing: 7 (clicks, higher than typical GT3 for Nordschleife stability at Flugplatz/Kesselchen/Schwedenkreuz)
• Downforce level: Medium-high
• Brake Ducts F/R: 3 / 2 (manage temps over 20km lap without overcooling in slow Adenauer sector)

KEY SETUP NOTE

• The 992 GT3 R's rear-engine polar inertia makes Flugplatz, Schwedenkreuz and Kesselchen the defining corners of the lap — a slightly taller rear ride height (70mm) plus stiffer rear ARB (7) keeps the car planted under crest-induced unload, preventing the snap-oversteer pendulum effect that punishes this chassis most on flat-out sections; sacrificing a touch of rear ARB stiffness for more front bite in Adenauer is not worth the risk at Nordschleife's high-speed sections.

TRACK GUIDE

• Hatzenbach: stay compliant on entry kerbs — don't overdrive the bumps, let the suspension work; small lift-and-rotate inputs only.
• Flugplatz/Schwedenkreuz: commit flat-out but respect the crest — any mid-corner steering correction here will be amplified by rear-engine weight transfer; trust the setup's rear stability.
• Fuchsröhre: brake before the compression, not during — heavy compression loading can lock inside wheels if trail-braked
