since this year I use a very handy tool. It's called crew chief and it basically gives updates over the radio about basically everything you can think of. You can also ask your crew chief for information (however, mostly of the time I don't use this because he doesn't understand me lol). Another very handy thing that it's also a spotter and tells you if there is a car next to you. This really helps with clean racing. You can download it here. In my earlier recorded races you can hear it working.
