Car Setups and Pitstop
Car Setup
You have a choice of preset setups or you have the option to go directly to the current setup:
- Safe Preset Setup
- Aggressive Preset Setup
- Wet Preset Setup
- Current Setup
Tyres
Tire Pressures
The current psi values are displayed in the tire app. Zursätzlich is represented by the different heights, at the three large bars, the differences in the three tire zones. At the front wheels above and at the rear wheels below.
- Drive 10 laps and watch the tire pressure. At the end of the curve and at the end of the longest straight.
- good values are dry 28,0 - 28,5 psi and wet / cold ~30 psi
- The default settings usually give you lower values. Increase the values in the tire setup menu to compensate for this difference.
- drive a few more rounds and watch the psi values.
Tire Temperatures
In the tire app, the three temperature zones (OMI or IMO) are visualized by three bars. Their color areas change depending on the temperature. Turquoise - Blue - Light Green - Green - Orange - Red. The temperature values can be seen either in the cockpit (depending on the vehicle type) or in the setup menu

Brake pads
| Value | Description |
|---|---|
| 1 | Very aggressive friction coefficient, max braking performance, aggressive disc and pad wear. Pedal modulation can be tricky if out of temperature or as it wears down. Use in hotlap and qualifying sessions, sprint races and can withstand 3 hours races. Risky and dangerous to use over 3 or 4 hours because the pads will wear down, overheat and lose linearity in brake pedal feel. |
| 2 | Very Good friction coefficient, very good braking performance, good disc and pad wear. Pedal modulation almost always good and linear, good feedback while overheating and gradual wear. Perfect for endurance racing, but can also be used in hotlap , qualifying sessions as well as sprint races as what it loses in performance, regains in braking modulation and predictability. The default choice for long endurance races, easily makes 12 hours and can make 24 hours race too with a bit of care. Will also overheat and lose linearity in brake pedal feel when worn out, but in a more predictable way and after much longer stints. Because of the lower friction, you could possibly use smaller brake ducts. |
| 3 | Moderate friction coefficient, braking zones can be longer in dry, very moderate disc and pad wear. Excellent pedal modulation also in cold ambient conditions, very linear pedal feedback. Excellent choice for wet conditions and very long endurance races. Very predictable and easy to modulate brake pad. Because of the lower friction, you should use smaller brake ducts. |
| 4 | extreme aggressive fiction coefficient. Max braking performance, extremely aggressive disc and pad wear, bad cold performance. This is a sprint race pad that can last about an hour but will show worse pedal feel, worse performance and overheating towards the end of the one hour stint. Those kinds of pads are not used in endurance racing, but included for demonstration purposes. |

| bump | stops the springs oscillation inward. A higher number wil dampen the compression at a slow rate more. | |

| fast rebound | A higher number wil dampen the decompression at a high rate more. | |

| Property | Values | Description |
|---|---|---|

| rear ride height | high is more forgiving, low is faster but tight. | |
| rearwing | a high number Increases drag,rear downforce, understeer and stability but lowers the topspeed and acceleration. | |
| brake ducts | Has effect on how fast the discs cool down and earodynamica. low number=cooldown slow, high number= cooldown fast. | |
| Front | ||
| front ride height | high is more forgiving, low is fast but tight. | |

Race Start Procedure
In ACC, a server administrator can specify three different methods for starting on a server (→ Server Configuration/settings.json) and whether a short or a complete Formation-Lap should take place.
Old Mode
- at the end of the countdown, all vehicles are released
- everyone can start the engine and drive off
- at 90 km/h the vehicles are throttled
- every driver has to keep his position independently without help. Whatever leads to problems.
- there are no penalties for wrong behavior here
with Driver Widget
Each driver is guided through the start of the race by a widget. The driver must always try to stay on the green scale here. First in the single arrow at 90 km/h, then in the double arrow at 60 km/h.
Free Mode
At the start of the race, only the traffic lights are shown. This is interesting for leagues that have their own race control.
Pitstop
A pit stop to refuel missing gas or repair damage is possible in practice, qualifying and racing. A driver can set his pit stop strategy in the vehicle setup (Fuel and Strategy) and change it while driving in the multifunction display (MFD). In a race without a compulsory pit stop, the pit lane is opened when the leader of the race has finished the first lap. In the middle of the lower part of the screen, the message of the race control is displayed: RCTL Pitlane is open
Server Configuration, see here: →eventRules.json
Mandatory Pitstop
- Variant 1: mandatory Pitstop possible throughout the race.
- Variant 2: mandatory Pitstop Window is limited in time. (Pitstop for damage repair always possible)
- Example: Race: 18 min / Window: 6min = from 6. Minute to 12. Minute
- What can be required for a mandatory pit stop?
- refueling
- change wheels
- driver swap
Server Configuration, see here: →eventRules.json
Driver Swap
(in MP: Swapping the riders works, but the operation is not intuitive and faulty! Last time tested: 17.11.2019 ACCv1.1.2)
Several drivers (in Blancpain real: 2-4) can form a team. All drivers can be on the server. The waiting drivers are not considered spectators in the sense of →Spectator Mode.
Using the Pit strategy page in the ( M )ulti(F )unctional( D )isplay (key: insert), the driver can assign a driver swap which will be automatically executed during the next pitstop.
In a training or qualification session, drivers of a team can use the chat command to swap drivers while the car is in the pit lane. Simply use the chat command and enter the space in the team widget. For example in "& swap 1" the driver changes to the driver who comes first. The waiting driver must be on the server.
Server Configuration, see here: →eventRules.json and →entylist.json
