        Waste of money

        It doesn’t fit. Not even close. It hits the driveshaft before you have enough threads to even start the nuts. I called BMR when I ordered it and they said it would fit. Well they were wrong.

        Want work with BBK off-road X-Pipe

        This looks like a solid loop system, but it totally will not work if you have a BBK off-road X-Pipe on your car, which I also bought through American Muscle. I live in Alaska so it will be a pain to send this back. You think AM might mention this, especially since they have the list of all mods on my car (I bought most of them there). When purchasing the website indicated that this would fit my car:(

        Quality part.

        The install went pretty easy just did it with my race ramps. I have the SVT package so I need to verify I have it aligned so it does not rub. I need to put more miles on to do this.

        Great fit, easy install

        15 minute install of a well made stamped part. Finish is done well on all surfaces. Tucks up under the body well with clearance all the way around the drive shaft.

        Tunnel brace with safety loop

        It looks good but when you lift the car off the ground the driveshaft comes in contact with the brace itself. As long as you're not flying over bumps it will be fine

        added for safety

        I actually had someone install this when I had my o/r pipes installed. I purchased both front and rear loops from AM. I know over kill. I have a VMP GEN2 w79mm pulley, JPC Budget E85 fuel system, etc give or take 700 rwhp, Just in case when I go to the strip

        Go With This Brace - Loop!

        I looked through EVERY option for a some driveshaft safety. This is a very nice product. It's well made and fits great - zero issues, and I have welded subframes! This comes with the brace AND loop, which is a far better design than any other I've seen. It's also a good deal vs other loop only products, IMHO. Installed on 2011 GT. About an hour or so, faster if you have a lift.

        Peace of Mind

        Installed this rear safety loop along with the front loop at the same time. As with the front loop, this rear loop installs easily, but unlike the front, the driveshaft does not need to come off. I have not had any issues with it rubbing as noted in other reviews with the stock driveshaft.

        was easy to install expecially because was installing the al driveshaft at the same time. wanted extra safety after some of the stories i herd about with the origional driveshaft. after a week or two, hit a couple of big bumps with a loud noise, diddn't know if the springs were bottoming out or the driveshaft was hitting the loop. got under the car and sure enough it was scratched. luckly it was only cosmetic, it did not damage the driveshaft. so i left the brace on but took off the loop. it should still protect in case of failure, and checked to see if it would hit the brace. i would almost have to be airborne for it to hit.
