BBk b/c...
if you want racing seats for added safety to go to the track and race. your first going to need to be able to stop otherwise racing seats will do you no good. your going to need better brakes for the higher speeds that you will encounter on the track. do this first for safety on the track especially with upgraded suspession( which allows you to carrry more speed through the corners) and then get the racing seats and harness for more safety on the track. you probably would want to get a rollcage too if safety on the track is your main concern. my 2 cents

Depends on your other mods....>
As the car gets faster, the need for brakes increases because you find yourself using more of that power. That's what happened to me. Brakes were way down the list, but as output got closer to 300hp, the need for them became evident..
Seats are a nice to have, but down the list a bit..

bbk isn't needed unless you are seeing fading...
racing seats and harnesses are needing if you have trouble staying in place during cornering. They are also safer in the unfortunate event of an accident.
