I recently got the Rocket Bunny diffuser, and it doesn't come with instructions or anything, so my question to those who've bought it, how does the center piece mount to the bumper?

3m tape? or just bolt through it?
The side pieces are obvious and have bolt holes so I'm guessing 3m tape for the center. unlike the TS diffuser

thanks

 

bolts, I wouldn't trust 3M tape after being weathered and might fly off!

or do both

 

Did you mount yours and if you did do you got pics of brackets you made?
