@Bob Luneski Heres a basic list of the apps I use when racing, not necessarily all at once, but some for practice/quali/race etc.
If you have any questions about any of these, don't hesitate to ask, or check youtube. Many have tutorials for installation and use, and many of us here have probably had the same "issue" you might come across
Crew Chief - your spotter, your friend, your biggest critic
Helicorsa - shows where cars are around you like radar, I use this instead of the kunos car radar app
Sidekick - an all in one speedo & dash. Shows delta, tirewear, timing and much more
CBV Fuel Calculator - fuel calculator
ProTyres - I use this instead of the kunos tire app, tire wear, pressure
Camber Extravaganza - shows you how "correct" your camber is midturn - I don't use this during the race
SimHub - sends data to a second screen, timing, maps, etc, very customizable
Substanding Extended - I use this instead of the kunos leaderboard (I think the kunos app is toggled on/off with f9) Also comes with overall & class position apps
Track Map Display Extended - sometimes I use this in place of the kunos map app (usually for Sunday multiclass races), otherwise I use kunos map app mostly
Sol - Make your game look pretty
Lastly, I use also use the FFB option & viewing settings for tweaking controls per car that are default kunos apps along with the performance delta (Kunos app) and the virual mirror (think f11 toggles that) -

Think thats it, but again, ask any questions you have. Don't feel like you need all of these (most of us probably use the first three apps), but I'm on a single screen and like info, so this is my collection
Here's how it looks usually in a race. Some overlap with info, but I like to be able to glance quickly and see what I need
