Great look and easy install!

This only took me 2 hours to install! It didn't come with instructions so I used the ones for the Roush part. Very similar. I had to get a buddy help detach and reattach the assy to the car. Other than

  • I had to drill holes for my parking sensors. It would be nice if they had an option for pre-drilled holes.

rear parking aids...disable? Is it possible to completely eliminate the rear parking sensors mounted in/on the factory rear diffuser and not have to drill holes to mount them in the new GT 500 diffuser, or can I simply use the info center, select off and cut/or cap the end of the wires?

Would it be feasible to try to adapt this diffuser to a 2008 GT? Maybe a little twist and shout could be applied?

    Rear-ly Awesome...

    The product itself is top notch but unfortunately there is no installation guide with this item. There is some guess work involved but the entire install is pretty easy but requires some specific tools - mainly push pin pliers! The item comes with these two tabs - AND THEY LOOK BROKEN BUT THEY ARE NOT. I went through some pain trying to figure this out. Install takes about 2 hours - maybe more. But some has been able to do in 1 hour. Overall it gives the mustang a more aggressive look from the back. Good job AM!

    Much meaner looking

    Part arrived well packed from AM. Install took a little longer for me because my 2012 V6 MCA has the reverse sensors in the diffuser, so I needed to drill holes for the sensors in the GT500 diffuser (measured 10 times, cut once!). Fitment is perfect, looks like it came from the factory with this diffuser on it.

    Nice looking rear

    It took me about 1 1/2 hours to install. Much more aggressive look than the factory rear diffuser on the V6. Great bang for the buck. Very satisfied with my new rearend.

    looks awesome

    The rear diffuser took me about an hour and 45 mins to install and it looks great! it popped right into place after removing the stock part. Its a great look for any mustang and would suggest it if you want your mustang to look better then it already does.

    Fast and easy install

    The fitment was a tad off here and there but only a perfectionist would notice it. The install instructions are very acurate except it didnt take me 3 hours. it took me exactly 1 hour to do from start to finish and i by no means rushed or had anything ready. I planned on it being 3 hours so i didnt care how quickly i worked at it. I do recommend to have needle nose pliers, says optional but its a must if you want to get some of the push plugs out.

    Huge improvement

    The weakest look on them 2011/12 mustangs is the rear end. This improves it alot and makes it look more muscular and different. for $150 this is a great buy and upgrade

    Awsome part and customer service

    First part had a little scratch on the visible area but AM was happy to send me a replacement for free of charge which was in perfect condition. Thanks for the great customer service and email conversation from Karen at customer support. This diffuser gives aggressive look and it is made with high quality material. Installation was easy as well. Very straight forward. This is must have item for all the GTs V6s.
