Porsche 911 GT3 R Rennsport

TYRES

• Compound: Dry Slick (Hard qualifying compound)
• Front Pressure: 26.3 PSI
• Rear Pressure: 25.8 PSI
• No tyre blankets in AC Evo — tyres must be built up on an out-lap via weaving and brake heating before the flying lap.
• Optimal operating temperature: 85–95°C (peak grip window), target 90°C core for both axles on the hot lap.

ELECTRONICS

• TC1: 3
• TC2: 1
• ABS: 4
• Engine Braking / Brake Magic: 4
• Brake Bias: 54.5% front (adjust to 55.0% if front locking under late braking at T1/T5)

SUSPENSION

• // FRONT
• Ride Height: 55 mm
• Wheel Rate FL / FR: 145000 N/m / 145000 N/m
• ARB: 85000 N/m
• Brake Torque Multiplier: 100%
• Brake Bias: 54.5%
• // REAR
• Ride Height: 60 mm
• Wheel Rate RL / RR: 160000 N/m / 160000 N/m
• ARB: 110000 N/m
• Diff Preload: 45 Nm
• Diff Coast: 0.7
• Diff Power: 0.4

DAMPERS

AERO

• Front Splitter: 3 clicks (max attack, low-drag Red Bull Ring config)
• Rear Wing: 6 (of typical 1–10 scale) — slightly higher than standard GT3 trim to stabilise T3/T4 crest
• Downforce Level: Medium-high, biased toward rear stability
• Brake Ducts: Front 2 / Rear 2 (single lap — minimal cooling need, prioritise aero tightness)

KEY SETUP NOTE

• This rear-engine GT3R wants a stiffer rear ARB and slightly taller rear ride height than rivals to control the pendulum effect over the T3–T4 crest; too low at the rear invites a snap on exit of T9 exactly when you need full throttle commitment onto the main straight.

TRACK GUIDE

• T1 Castrol Kurve: brake as late as physically possible in a straight line — trail brake only lightly, this car's high coast lock (0.7) stabilises entry rotation.
• T3 Schlossgold: committed fast right uphill — stay full throttle, let the aero and stiffer rear ARB keep the rear planted.
• T4 Rauch/Rindt: car goes light near-flat over the crest — smooth steering input only, any correction here costs the whole back straight run.
• T9 Hans Ernst hairpin: this is the lap-defining corner — sacrifice entry speed for a clean, early throttle application; power lock (0.4) gives controlled traction without snapping on exit.
• Biggest time gain: minimizing rotation scrub at T1 and nailing throttle timing at T9 — these two corners define 60%+ of your lap delta.

THEORETICAL BEST LAP

• 1:26.800 — theoretical optimal sector composite, GT3 Pro-level single hot lap, dry/green track, based on current GT3 pace benchmarks at Red Bull Ring.
