I've been wanting a lightbar for my WRX for some time now now but most of the options on the market were either too big to fit behind the grill (there is only about 2" clearance) or would require me to do some major mods to the lower hole, which I was not wanting to do. Putco came out to the shop a few weeks back and introduced me to their 20" LED bar that was only about an inch thick and would fit perfectly behind the grill. I was able to mount this bar behind the grill using slightly modified mounts that came with the bar, to factory bolt locations that support the AC condenser. The only thing I had to do to complete the installation was to extend out the switch lead a few feet to allow me to mount the switch in the location I had selected. For it's small and compact size the bar puts out a good amount of light. I went out on some local dark and twisty roads and defiantly felt more confident driving due to my new found increased visibility.
I chose behind the factory grill for my install location. I was able to use the supplied brackets in factory bolt locations for the install.
Clearance behind the grill was tight, a slight bend on the supplied bracket was made to allow for clearance.
