Porsche 992 GT3 R Rennsport

TYRES

• Compound: Slick (S)
• Front Pressure: 26.5 PSI cold start (target 27.0–27.5 PSI hot after 4–5 laps)
• Rear Pressure: 26.0 PSI cold start (target 26.5–27.0 PSI hot after 4–5 laps)
• Camber FL / FR: -3.4° / -3.4°
• Camber RL / RR: -2.6° / -2.6°
• Toe Front: 0.05° out per side
• Toe Rear: 0.20° in total
• Optimal Operating Temperature: 85–95 °C (peak grip around 90 °C). Check hot pressures after lap 5 and adjust by ±0.5 PSI.

ELECTRONICS

• TC: 3 (the 0 on the reference lap is a one-lap pace setting. Over race distance, a little TC protects the rears on exit from Tosa, Rivazza and Variante Bassa)
• TC Cut: 1
• ABS: 3 (Tamburello and Tosa are heavy braking zones, and low ABS means lock-ups that flat-spot tyres on a long stint)
• Brake Bias: 59.5% front (starts at 60.0%, with a slight rearward shift to help rotation on trail braking)
• Engine Map: 2

SUSPENSION

• // FRONT
• Ride Height: 62 mm
• Wheel Rate FL / FR: 195000 N/m / 195000 N/m
• ARB: 52000 N/m
• Brake Torque Multiplier: 100%
• Brake Bias: 59.5%
• // REAR
• Ride Height: 72 mm
• Wheel Rate RL / RR: 175000 N/m / 175000 N/m
• ARB: 38000 N/m
• Diff Preload: 90 Nm
• Diff Coast: Fixed in ACC homologation, not adjustable. If the Evo build exposes it, set 0.4
• Diff Power: Fixed in ACC homologation, not adjustable. If the Evo build exposes it, set 0.3

DAMPERS

AERO

• Front Wing / Splitter: Fixed on this car, no adjustment
• Rear Wing: 8 (the 992 likes a higher wing than most GT3 cars, and 8 gives rear stability through Piratella and the Variante Alta flat-out commitment without hurting Rivazza exit)
• Downforce Level: Medium-high
• Brake Ducts: Front 2 / Rear 2 (moderate cooling for the heavy braking at Tamburello, Tosa and Rivazza, which keeps temps stable over a long run)

KEY SETUP NOTE

• Fuel load and tyre deg decide the race here, so the rear is set deliberately compliant (soft rear ARB, 72 mm rear ride height) to keep traction and protect the rear tyres out of Tosa, Rivazza and Variante Bassa. A stiff rear makes the 992's pendulum effect worse and cooks the rears by mid-stint. Aggressive rotation comes from trail braking into the front, not from stiffening the rear. The ride heights also leave enough clearance for the kerbs at Tamburello and the compressions at Acque Minerali.

TRACK GUIDE

• Tamburello (T1): Brake late but straighten the car before turn-in. Take the kerb on the inside, but avoid the high outside kerb, which unloads the rear. Stay stable and get the power down early for the run to Villeneuve.
• Tosa (T5): This is the main overtaking spot and the biggest traction zone. Late brake, trail in to the apex, and rotate with brake pressure. Be patient with the throttle and straighten the wheel before going full power, since the rear tyres suffer here over a stint.
• Piratella (T8) and Acque Minerali (T9/10): The car pitches under braking at Piratella, so stay smooth on the way in. In the Acque Minerali dip the car bounces, so use the kerbs sparingly and keep the car straight on the compression.
• Variante Alta (T13): Flat-out commitment. Any lift unsettles the car, so brake in a straight line, trust the aero, and carry minimum speed through the chicane.
• Rivazza 1 and 2 (T16/17): Sacrifice the Traguardo chicane (T18) for a clean Rivazza exit. A late apex on Rivazza 2 gives the best run to the line. Most of the lap time is won on the back straight run-up and at Rivazza exit.
