I have an 05 with stock rear bumper with the rear sensors, I really like the a-spec/mugen rear. Does the a-spec/mugen have holes for the sensors??

 

The Mugen rear is different than the A-Spec rear.

Mugen Rear


A-Spec Rear


But to answer your question. It is only the rear lower spoiler. So you need to drill the hole onto the bumper to add the back up sensor.

 

so the aspec and mugen are just add ons?? Meaning it goes on top of my stock bumper?

 

Yes they are. Not full bumper spoiler.
