TYRES
- Slick — Medium compound. F: 2.05 bar / R: 2.00 bar (hot target). Cold set: F 1.95 bar / R 1.90 bar. Blanket temp: 80°C. Optimal operating window for max grip: 90–105°C (core).
ELECTRONICS
- TC: 4 (single-make cup car, fixed-ish electronics — keep moderate for aggressive traction on T1/T13 exits)
- ABS: 3 (allows late braking without excessive pedal travel loss)
- Brake Pressure: 96%
- Brake Bias: F: 56% / R: 44%
DRIVETRAIN
- Fuel Map: Map 2 — standard mixture, balances race pace with fuel economy over stint; switch to Map 3 (richer, +low-end response) only for qualifying-style out-laps or overtakes.
- Gear Ratios:
- 1st: 3.083
- 2nd: 2.235
- 3rd: 1.720
- 4th: 1.400
- 5th: 1.185
- 6th: 1.038
- Final Drive: 3.583

AERO
- Front splitter: fixed cup-spec (no adjustment) — verify ride height controls front balance instead
- Rear wing: 6 (of typical 1–9 scale, biased toward stability for Campsa/T16)
- Downforce Level: high-stability setup (rear-biased) for banked/high-speed sections
- Brake Ducts: F 4 / R 3 (Medium compound, race-length stint, prevent overheating without underheating in braking zones)
KEY SETUP NOTE
- This is a fixed, spec cup car — most gains come from ride height and damper balance rather than aero or diff changes; keep rear ride height slightly higher than instinct dictates to prevent snap oversteer through Campsa (T10) and on exit of the T13/14 hairpin under aggressive throttle application.
TRACK GUIDE
- T1 Elf: Late brake hard in a straight line, get all braking done before turn-in — this car snaps if trail-braked deep into the hairpin; prioritize a clean, early throttle application for the long run to T2.
- T2-T4 Renault: Carry momentum — minimum lift approach, focus on car stability at T3 apex; rear ARB setting above helps resist mid-corner rotation at high spe
