Circuits
Circuit Characteristics
Each circuit in BSR has a unique set of attributes that affect race strategy and car setup.
Core Attributes
| Attribute | Effect |
|---|---|
| ----------- | -------- |
| gt_lap_time_min | Fastest possible lap (baseline) |
| gt_lap_time_max | Slowest possible lap (penalty window) |
| race_laps | Race distance in laps |
| overtake_pct | Base overtaking difficulty (15 = 15%) |
| tire_wear_per_lap | Base tyre degradation per lap |
| weather_sensitivity | Weather impact scale (1-10) |
Setup Importance
These attributes determine how much each setup parameter matters:
| Attribute | Setup Parameter Affected |
|---|---|
| ----------- | ------------------------ |
| kerb_sensitivity | Suspension |
| downforce | Aero |
| speed | Gearing |
| braking_stress | Brakes |
| mechanical_grip | Diff |
Each is rated 0-10. Higher values = more important to get that setup right.
Example Circuits
High Downforce (Monaco-style):
- downforce = 10
- speed = 3
- Aero setup is critical, gearing less so
- downforce = 3
- speed = 9
- Gearing matters most, aero less important
Continent & Country
- <strong>Continent</strong> - affects weather climate model
- <strong>Country</strong> - desert countries have near-zero rain chance (fixed 5%)
- European circuits have higher rain probability (+10%)
Strategy Considerations
- Study each circuit's attributes before allocating engineering and setting up the car
- Prioritise part upgrades for attributes that matter most at upcoming circuits
- Check weather sensitivity to gauge whether rain is a factor
- High tyre wear circuits require careful pit strategy
