Lotus Exos 125

TYRES

• Slick Medium (M) — Front 23.5 PSI cold / Rear 25.5 PSI cold (targets ~27–28 PSI hot front, ~29 PSI hot rear). Reference lap's hot pressures (23.9/24.8/25.9/26.1) were logged at only 15°C air/21°C track — if dry-session ambient is warmer, starting slightly lower cold compensates so the quali lap (run on a flyer from cold/one lap of heat-cycling) doesn't come in underinflated after only partial warm-up. No tyre blankets assumed — these cold values are the launch point for a single banzai lap.

ELECTRONICS

• TC: 0 (off) — open-wheel single-seater, aggressive style, maximum rotation requires no TC intervention.
• ABS: Off — car has no ABS by default; do not invent it.
• Engine Braking / Brake Magic: N/A (not adjustable on this model).
• Brake Bias: 60.0% front (carry over from reference lap — correct baseline for a cold-tyre low-temp track; verify no front lockup on Tosa/Rivazza entry, trim 0.5% rearward if it locks).

DAMPERS

AERO

• Front wing: 4 (of available range) — enough bite for Tamburello/Villeneuve rotation without killing Variante Alta top speed.
• Rear wing: 5 — biased toward stability for Rivazza exit and Piratella commitment; single-lap attack favors slightly more rear download than outright straight-line speed.
• Brake ducts: N/A (tyre wear irrelevant this session; leave at default mid setting if present).

KEY SETUP NOTE

• This car's low mass and high front grip mean the single biggest lap-time lever at Imola is ride height stability through Tamburello and Acque Minerali — any contact with the floor on the kerbs upsets rotation into the next apex; keep the rear slightly higher than the front to protect the diffuser through the compressions while still allowing sharp front turn-in.

TRACK GUIDE

• Tamburello entry: brake late but straight-line only, trust the front — car should rotate hard on initial turn-in with this front wing/ARB balance; don't carry excess rotation onto the kerb exit.
• Tosa hairpin: this is the lap-defining corner — sacrifice entry speed for a clean, early throttle application; the long run to Piratella rewards traction over mid-corner speed.
• Piratella: brake in a straight line before the crest, the car pitches hard under trail-braking here — get braking done early, then commit to the uphill apex flat if possible.
• Acque Minerali: ride height and damper settings are tested here — stay smooth on the wheel through the compression, aggressive steering inputs will unsettle the rear.
• Rivazza 1&2 into the final chicane: exit speed from Rivazza 2 is worth more than the entry to Traguardo — don't brake early for the final chicane at the cost of Rivazza 2 exit, this is where most time is won onto the pit straight.
