Twitter Bootstrap - Enhance Navbar Content to the Maximum - css

Question

I have the following:
Basically, I want the text "Home" to begin in line with the edge of the car picture. The last nav item should end on the right´. The Navbar is placed inside of a container-fluid. All li-elements between "Home" and "Inscriptions & Contact" should be centered. How can I accomplish that?
My Code:
<nav class="navbar navbar-default text-uppercase">
<div class="container">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
</div>
<!-- Collect the nav links, forms, and other content for toggling -->
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav">
<li class="nav-first">Home</li>
<li>Instructeurs</li>
<li>Véhicules</li>
<li>Examen & Liens</li>
<li class="nav-last">Inscriptions & Contact</li>
</ul>
</div><!-- /.navbar-collapse -->
</div><!-- /.container-fluid -->
</nav>
And this is what I changed in my custom css file:
#font-face {
font-family: MyriadPro;
src: url("../fonts/MyriadPro-Regular.otf");
}
.navbar {
font-family: "MyriadPro", sans-serif;
font-size: 18px;
}
.navbar-default {
background-color: inherit !important;
border-color: none !important;
text-align: center;
}
.nav > li > a {
padding-right: 50px !important;
padding-left: 50px !important;
}
.navbar .navbar-nav {
display: inline-block;
float: none;
vertical-align: top;
}
.navbar .navbar-collapse {
text-align: center;
}
.active {
background-color: gray;
border-radius: 15px;
}
.navbar-nav>.active>a, .navbar-nav>.active>a:hover, .navbar-nav>.active>a:focus {
color: #8D1917 !important;
}

Answer 1

You can try this using table layout (similar to btn-group-justified in Bootstrap).
CSS:
.container-fluid > .navbar-collapse,
.container-fluid > .navbar-header,
.container > .navbar-collapse,
.container>.navbar-header {
margin-left: -15px;
margin-right: -15px;
}
.navbar-nav-justified {
display: table;
width: 100%;
table-layout: fixed;
}
.navbar-nav-justified > li {
display: table-cell;
vertical-align: middle;
float: none;
width: 100%;
}
