You are an experienced race engineer. The following is a telemetry report for one lap in Assetto Corsa Competizione (GT3/GT4). Perform a detailed analysis of car balance and handling based on the available telemetry channels. ## Important note ACC does not export car setup parameters to telemetry — the in-game setup table is all zeros and is omitted from the report. The balance and handling analysis is derived entirely from **telemetry channels**: corner balance, tyre temperatures and pressures, brake temperatures, and suspension travel. ## Data format **Corner balance** — per corner: - `gLat_max` — peak lateral G-force [G] - `steer/g` — steering angle to lateral G ratio: high = steering a lot for the G = understeer - `front|slip|` / `rear|slip|` — average absolute slip of front/rear axle in the corner zone - `balance` — outcome: US (front axle slips more), OS (rear), — (neutral) **Tyres** — per wheel: - `wearΔ%` — wear over the lap - `surf min/avg/max °C` — surface temperature - `carc min/avg/max °C` — carcass temperature - `pressure` — hot pressure [PSI] **Brakes** — min/avg/max temperature per wheel [°C] **Suspension**: - Rake — average front vs rear ride height [mm]; positive rake = nose higher than tail - Roll per corner — body roll in each corner [mm]; shows outer-wheel loading **Lap phases** — average tyre surface temperature across three equal lap segments --- ## Task Analyse each point. Back every conclusion with numbers from the report. ### 1. Mechanical balance - Corner balance: systematic US or OS across most corners? - Analyse fast (high gLat) vs slow (low gLat) corners separately — different patterns? - High `steer/g` = car demands more steering for the load level = understeer tendency; low `steer/g` with high rear slip = oversteer - GT cars are sensitive to front/rear spring and anti-roll bar balance: abnormal Roll per corner may indicate a soft spring or weak anti-roll bar on one axle ### 2. Differential and traction - From `spin%` in the corner table: high rear slip on exit indicates an aggressive on-throttle differential lock or premature throttle application - If `spin%` is consistently high in slow corners but modest in fast corners — on-throttle differential setting is the likely cause - Check whether rear slip is symmetric across left and right sides — asymmetry suggests a geometry or tyre pressure issue ### 3. Tyre thermal window - Pirelli GT tyre operating window is approximately ~70–90°C surface; outside this range grip is compromised - Are tyres in window; who overheats, who underheats - Surface vs carcass delta: large gap = tyre overheating on the outside but cold carcass (delamination risk), or vice versa - Wear: even across 4 wheels — abnormally high wear on one wheel signals load imbalance - Lap phases: normal warm-up pattern — should rise in phase 1 and stabilise ### 4. Tyre pressures - Hot pressure (from Tyres): too high = overheating and loss of contact patch; too low = under-temperature, tyre wanders - F/R pressure balance: asymmetry affects mechanical balance - L/R pressure difference on the same axle — sign of asymmetric heating or incorrect cold starting pressure ### 5. Brakes - Temperature range: <200°C = cold (poor braking), 350–800°C = normal GT working range, >900°C = dangerous overheating - L/R asymmetry: different temperatures on same axle = uneven pad wear or brake balance issue - If rears are consistently hotter than fronts — bias is too far rearward; if fronts dominate — bias is forward; both reduce braking stability ### 6. Suspension - Rake: moderate positive rake is standard for GT; very high rake increases rear aerodynamic load but can cause a lazy front on turn-in - Roll per corner: typical roll 3–8 mm; large roll = soft suspension or weak anti-roll bars; small = stiff, sensitive to bumps - L/R roll asymmetry in the same corner indicates uneven suspension travel or load distribution ### 7. Recommendations Per identified issue — what specifically to change (direction of adjustment) and expected effect. Prioritise by lap time impact. --- Below is the attached report. Begin analysis.
