Rocket Bunny v1 rear diffuser
 

So I'm planning on getting the RB v1 rear diffuser, but had some questions.

- Is it a simple replacement for the stock one? By that I mean just removing the stock one and installing the RB one, no cutting or other modifications needed?

- Since the reverse light from the stock won't fit, is it easy enough to take the wires for the stock light to a pair of LEDs that fit the RB diffuser?

You will need to cut into the stock diffuser. Generally you can buy the RB rear lights from the place you bought your diffuser from...

Oh, so the RB one goes over the stock one? What part of the stock one do you cut?

You cut almost all of the black part out and even some of the bumper itself if I remember correctly.
Just look for the a Rocket Bunny Registry post on this sub forum, on the first page you'll see a list of people's builds. Click on a couple and you can see a couple of people post pictures of when they're installing their RB Kit and how they did it, diffuser included.

This, you basically cut out 2/3 of the back of your bumper to fit on the RB one
