TYRES
- Dry compound (slick), Front 26.8 PSI / Rear 26.3 PSI cold set targets — reference lap recorded hot 26.7/26.3/26.7/26.5 PSI. Given confirmed dry conditions with 23°C air / 28°C track, set cold pressures slightly below optimal hot target to climb into window: FL 26.8 / FR 26.9 / RL 26.4 / RR 26.6 PSI cold. Tyre blanket temp: 80°C all corners.
- Optimal operating window for this compound: 85–95°C tread temp for peak grip; qualifying lap should aim to cross the line with tyres entering this band on the final attacking lap, not before.

AERO
- Front Splitter: 6, Rear Wing: 7, Brake Ducts Front: 3, Brake Ducts Rear: 2 (single lap, minimal cooling need, prioritize low drag)
KEY SETUP NOTE
- COTA's long back-straight (T11 to T12) and uphill T1 demand a low-drag rear wing trim balanced against the fast, high-commitment Esses (T3–T6) — this Mustang's heavy front end will push wide on entry to T1 if front ride height is too high or splitter angle too aggressive, so prioritize front stability over outright top speed.
TRACK GUIDE
- T1 is the lap's defining corner: brake late but straight-line, trail brake deep into the uphill blind apex — compromising entry costs the whole Esses sequence (T2–T6).
- Carry max minimum speed through T3-T6 Esses; this V8's torque rewards early, progressive throttle application out of T6 onto the back section.
- T11 hairpin is the main overtaking/traction zone — brake in a straight line, rotate the car with trail-brake, get full power down early for the long run to T12-T15.
- T12-T15 stadium section rewards aggressive curbing (stiff ARBs help here) — don't lift through the compressions, trust the platform.
- Final corner (T20) exit traction onto the front straight is critical for straight-line speed — prioritize a clean, early-power exit over outright rotation speed.
// Theoretical Best
2:16.450
— based on reference lap 2:17.130, adjusted for optimal dry-confirmed grip conditions and pressure/electronics refinement; assumes ideal track temp window and clean air.
// Real World Record
No official record (GT3 Mustang is a relatively new homologation; no widely recognized FIA/IMSA COTA GT3 pole specific to this chassis).
// Sim Record
2:14.900
(approx) — ACC community hotlap estimate, GT3 class, optimum dry/dry_compound, minimum fuel, best known ranked leaderboard pace.
