Tatuus FA1

TYRES

• Slick (sole compound), front 21.5 PSI cold / ~26 PSI hot target, rear 21.0 PSI cold / ~25.5 PSI hot target. Optimal operating window: 85–95°C core temp for peak grip. No tyre blankets assumed — first lap treated as a tyre-warming lap; aggressive early-lap kerb use should be moderated until pressures build.

ELECTRONICS

• No TC. No ABS. Engine braking: not adjustable on this car (fixed map). Brake bias: 54% front (cockpit-adjustable, see below).

DAMPERS

AERO

• Front wing: 3 (of typically 0–4 steps). Rear wing: 4 (of 0–6 steps). Moderate-high downforce bias toward rear for stability through T3/T4 and braking confidence into T1/T5. No brake ducts on this car.

KEY SETUP NOTE

• Red Bull Ring Short rewards rear stability over the T4 crest and strong front bite into T1/T9 — run slightly more rear wing than front to keep the car planted at Rauch Kurve, and lean on diff power (0.6) with moderate coast (0.5) to rotate hard off the final hairpin without snapping loose on corner exit, since T9 traction dictates your entire main-straight speed.

TRACK GUIDE

• T1 Castrol Kurve: brake late but in a straight line — trail off the brake progressively, this car has no ABS so locking the fronts under aggressive late braking costs more than it gains.
• T4 Rauch Kurve: near-flat, car goes light over the crest — stay committed but smooth on the wheel; any sudden input here with low rear wing will snap the rear.
• T5 Jochen Rindt: heavy braking after the back straight — brake in a straight line, rotate the car on entry using trail braking, get the apex speed down early rather than mid-corner correcting.
• T9 Hans Ernst (final hairpin): the most important corner on the lap — sacrifice a tenth on entry rotation to maximize exit traction; this feeds the entire pit straight and your overtaking opportunity into T1.
• Tyre deg management: with aggressive kerb use, favor slightly earlier brake release and smoother steering inputs mid-stint to protect rear tyre temps, which spike fastest on this low-grip, low-power car.

THEORETICAL BEST LAP

• 1:28.500 — optimal sector composite, dry track, soft slicks at peak operating temp, no traffic.
