ND = new driver
OD = old driver
1) ND connects to server
2) ND tabs to his teams car, sets his driving view
3) ND brings up playerlist with N
4) OD enters pitlane
5) ND clicks 'T' in playerlist
6) during the pitstop, OD leaves the car in neutral *
7) OD accepts the driver-change by clicking the 'T' too
8) ND is in control of the car
faster variante:
5) ND clicks 'T' in playerlist
6) during the pitstop, OD leaves the car in 1st gear AND stays on throttle AND hold down clutch *
7) Holding down clutch requires only one foot/finger. So once the pit-stop is coming to an end (watch the messages about refueling etc) OD rapidly clicks the 'T' as fast as possible.
Do not attempt to "react" to end of pitstop, just continously spam the button! *click click click*
8) ND is also on throttle, but not on clutch
9) Once pitwork is finished, because of the click-spam ND will instantly get control
10) At moment of driver-change, clutch is suddently not pressed anymore and because engine & turbo are already spun up, acceleration is much better.
The car-take-over times out after a while. (about 30-60 seconds?)
So if you press it too early during the lap remember to 'refresh' it during the pitstop.
* That is important in case the driver-change did not work, (usually by mis-click) because once the car has moved you have to do another pitstop to try again.
