Setup Reference
Tire Pressure
Tire pressure is determined by the tire model, not just the chassis. However, for a standard racing kart setup (~150kg total weight with driver/robot):
| Tire Type | Cold Pressure (Bar) | Cold Pressure (PSI) | Notes |
|---|---|---|---|
| Soft/Medium Slicks | 0.75 ± 0.1 | ~11 ± 1.5 | Standard racing range (e.g., Vega Green/White) |
| Hard Slicks | 0.90 ± 0.1 | ~13 ± 1.5 | Endurance or rental compounds |
| Rain Tires | 1.20 ± 0.2 | ~17.5 ± 3 | Higher pressure to open treads |
Tip: For autonomous runs, consistency is key. Start at 0.8 bar (11.6 psi) all around and adjust based on tire wear and grip levels.
Maintenance
- Bearings: Check rear axle bearings (3 per side usually) and front stub axle bearings.
- Alignment: The Extreme has adjustable caster/camber pills at the front kingpins. Neutral setting is recommended for initial autonomous testing.
