Here are pictures of the Evosport roll cage for the E92 BMW's. The car pictured here belongs to my friend Ramiz who is getting an S85 V10 twin turbo swap (details on that to come later.)
This is a very well done cage with excellent welds and piping that is extremely similar to the factory M3 GTS setup. Before someone asks, yes, this is not the finished product pictured here and the pipes can be painted of course.
$3200-$3400, contact evosport for more details: www.evosport.com
