Porsche 992 GT3 R Rennsport

TYRES

• Slick (Dry Qualifying Compound), Front 26.5 PSI, Rear 26.0 PSI — no tyre blankets in AC Evo, build pressure via out-lap weaving and aggressive early braking. Optimal operating window: 85–95°C for peak single-lap grip.

ELECTRONICS

• TC1: 3 (minimum intervention for max rotation, aggressive driver can manage rear)
• TC2: 1
• ABS: 4
• Engine Braking: 4
• Brake Bias: 54.5% front (base, see suspension section for exact)

SUSPENSION

• // FRONT
• Ride Height: 55 mm
• Wheel Rate FL / FR: 165000 N/m / 165000 N/m
• ARB: 22000 N/m
• Brake Torque Multiplier: 100%
• Brake Bias: 54.5%
• // REAR
• Ride Height: 65 mm
• Wheel Rate RL / RR: 190000 N/m / 190000 N/m
• ARB: 28000 N/m
• Diff Preload: 50 Nm
• Diff Coast: 0.75
• Diff Power: 0.35

DAMPERS

AERO

• Front splitter: 4 clicks (aggressive, max front bite for late braking)
• Rear wing: 7 (high downforce — Nordschleife rewards stability over Döttinger top speed loss)
• Brake ducts F/R: 2 / 2 (single lap, minimal cooling needed, reduce drag)

KEY SETUP NOTE

• The 992 GT3 R's rear-engine polar inertia means a single lap setup must bias stability at Flugplatz/Schwedenkreuz/Kesselchen (high-speed commitment zones) through ride height and rear ARB, while sacrificing some mechanical rear grip via high coast lock (0.75) to prevent snap-oversteer on trail braking into Adenauer Forst and the Karussell entry — don't soften coast for qualifying, the risk of a late-lap spin outweighs the gain.

TRACK GUIDE

• Hatzenbach: carry speed through the direction changes, trust the compliant suspension setup — don't lift, the bumps are absorbed by the softer slow bump damping.
• Flugplatz: stay flat-out over the crest; the stiffer rear ARB and higher rear wing keep the rear planted as it goes light — any lift here costs 2-3 tenths.
• Fuchsröhre: brake late into the compression, let the heavy load settle the car, then get back to throttle early for the fast right — this is a major lap time zone.
• Adenauer Forst: this is where aggressive trail-braking rotates the car — use the high coast lock to stabilize, then get on power progressively to avoid triggering snap oversteer.
• Karussell: take the inside banked line, let the car ride up onto the banking — slightly softer front compliance helps the inside tyre stay
