I put the EVO-R kit last winter.
It's a bit of work to do it right, but nothing terribly difficult.
The fitment isn't great, but it's livable. I have an issue with one
fender (non-OEM body shop replacement) that makes it difficult
to get the bumper on just right. As it's an autox/track car, I don't
worry about it too much.
I didn't get the HID option. My FD is rarely used on the street.
Mostly I just wanted to get rid of the popups. The stock lights
look great, but it's easy to get surprised by the popups moving
if you work on your car a lot. I want to keep all my fingers.
Here are some pics of the install:
