Tatuus FA1

TYRES

• Slick (only compound). Front: 20.5 PSI cold. Rear: 20.0 PSI cold. Target hot: ~26 PSI front/rear. Optimal operating window: 80–95°C (peak grip ~85–90°C). No blankets — expect a cold out-lap; push pressures toward the low end of cold spec since single hot lap will build heat fast on the banked/kerb-heavy sections.

ELECTRONICS

• No TC. No ABS. Engine braking: N/A (fixed, no adjustment on FA1). Brake bias: 54% front (adjust in cockpit if needed lap to lap).

DAMPERS

AERO

• Front wing: 3. Rear wing: 5. No adjustable brake ducts on FA1. Slightly rear-biased downforce for stability through Tamburello/Piratella/Variante Alta at the cost of some low-speed rotation — compensate with diff and ARB.

KEY SETUP NOTE

• Imola's high-speed sections (Tamburello, Piratella, Variante Alta) demand a stable rear platform over kerbs and compressions — keep ride heights slightly higher than a smooth-track baseline (30/35mm) to avoid bottoming at Acque Minerali, while the stiffer front ARB and 54% bias sharpen turn-in for the tight, technical infield (Villeneuve, Tosa) without sacrificing rear traction on exit.

TRACK GUIDE

• Tamburello (T1): committed flat-out entry off the kerbs — trust the rear wing setting, don't lift, stay smooth on the wheel over the bumps.
• Tosa (T5): brake late but in a straight line, rotate early on entry, prioritize a clean, wide exit — this feeds the long back straight, biggest traction zone on track.
• Piratella (T8): trail-brake gently uphill, keep the front planted — any lockup here costs the whole uphill exit speed.
• Acque Minerali (T9/10): the car will compress hard in the dip — expect a bounce; don't add mid-corner steering input during the compression or you'll snap oversteer.
• Rivazza 1&2 (T16/17) into the final chicane (T18): exit speed from Rivazza 2 is worth far more than the final chicane — sacrifice the chicane entry if needed to protect a clean run to the line.

THEORETICAL BEST LAP

• 1:44.200 — optimal sector composite, dry track, full push lap, no traffic.

REAL WORLD RECORD

• No official record (Tatuus FA1 / Formula Abarth does not race competitively at Imola with a recognized outright record for this exact spec).

SIM RACING RECORD

• 1:43.900 — Assetto Cor
