Tatuus FA1

TYRES

• Slick (sole compound), front 21.0 PSI cold / rear 21.0 PSI cold, settling to ~26 PSI hot. No tyre blankets in Formula Abarth — expect a cold out-lap, optimal grip window at 80–95°C tread temp. Single hot lap strategy: push hard from lap start to get pressure/temp into window within 1.5 laps.

ELECTRONICS

• TC: N/A (none fitted)
• ABS: N/A (none fitted)
• Engine braking: fixed (not adjustable on FA1)
• Brake bias: 54.0% front (adjustable in cockpit, see below)

DAMPERS

AERO

• Front wing: 3 (of available steps), Rear wing: 4 — slight rear-biased downforce for Tosa/Rivazza traction and Tamburello/Variante Alta stability. No brake ducts on this car.

KEY SETUP NOTE

• Imola's mix of high-speed commitment (Tamburello, Variante Alta) and tight traction zones (Tosa, Rivazza) means you can't run minimum downforce for a "quali trim" — the FA1 is light enough that a slightly higher rear wing setting pays off everywhere except the final chicane; stiffen rear ARB slightly over base road-course settings to sharpen rotation into Tosa without sacrificing Rivazza exit stability.

TRACK GUIDE

• Tamburello (T1): committed flat-in-top-gear chicane — ride height and damper settings above are tuned to not bottom out on the kerbs; any instability here costs the whole lap down the next straight.
• Tosa (T5): brake as late as possible in a straight line, rotate hard on entry, prioritize a clean, early throttle application over apex speed — this exit feeds the longest flat-out section of the lap.
• Piratella (T8): trail-brake deep but smoothly; the car pitches forward uphill under brakes, so avoid late trail-brake spikes that unsettle the rear.
• Acque Minerali (T9/10): the dip compresses suspension hard — don't run minimum ride height here or you'll bottom and skip, costing rotation through the second part of the chicane.
• Rivazza (T16/17): this is the biggest lap-time corner on the circuit — sacrifice a tenth in the final chicane (Traguardo) if needed to protect a clean, full-throttle Rivazza 2 exit onto the pit straight.
