color match Is this part the same color as the CS front clip and the rocker panels that come standard on 2012 Mustangs?

  • Yes, these parts are unpainted with that charcoal rough texture feel to them like from the factory.

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?

winner

  • The rear sensors are completely removable.

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

Ripter

  • I don't think it would work on a 2008 GT. When I added to my 2010 GT it attached to preexisting mounting screws of the standard 2010 bumper and quarter panels. Since the '08 and '10 have physical mouldings I doubt it would work very well. I hope that helps.

    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.

    Rear Diffuser

    Part arrived as freight on an 18 wheeler. Must be because of the size dimensions, certainly not the weight. The driver finally made it out of the cul-de-sac...in reverse. The install took about 2.5 hours for me (interruptions from the wife). I would recommend you get a "Trim removal Kit" from your local auto store. It will save the clips and make the install much faster. This item should be standard on all dual exhaust Mustangs. It gives the car a more aggressive look from the back and completes that modern/retro combination for the S197 rear end. Thanks AM! Saving for the next item!!

    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.

    Awesome Product. Better than OEM.

    I was pleasantly impressed by this diffuser. The quality and appearance is better than the OEM part ford had installed on my GT. No instructions provided, but very simple install. Take out the tailights, take off rear wheels (for better access to a few screws), unhook a few wire harnesses, and pop off the bumper. Took me about 2 hours to install by myself. Great product and as always, fast shipping from American Muscle.
