I'm not experienced in Project Cars 2, nor with VR in driving games. I spent about 30 minutes practicing the track and then recorded a 2 lap race with myself (only way to save a replay, and to get the broadcast style replay).
I use a Logitech Driving Force GT wheel and HP Reverb VR headset.
Assists were set to Authentic, so a little traction control etc. are applied. Not sure if it's per car or what.
