    calvins review

    From what i can tell the wing is an upset. it has a very ugly mount. it could potentially mount wide but it will not look as it does on the advertisement. Reason. when you take it out of the box it will look crazy nice but then put it on the rear of your mustang and where it should mount will over shoot the entire rear end of your mustang so American muscle sends with it an added 2 pieces to mount the wing in the original spots of where the old wing came off. which then now you still have an over hang of 2 potential mounting areas. which appears ugly in the end. You almost have to cut the first set of mounting screws and off and completely redo the wing to go with the added parts that come with this kit that allows for a match for installation. A real upset. Dam. Nothing is as advertised. The front replacement bumper is some flimsy piece of plastic that might flap in the wind once installed. Yet the original bumper mounts firm and true. Dam. Im certain that once the unit is done being painted i will like it all but will know it all needs to be altered just to look good.

    Roush body kit

    I gave the kit a five star rating because I bought the roush body kit a while back and it fit perfect! I do recommend mocking up the bumper Brackett's before you rivet them even though they have pre drilled holes because if you're like me you don't want even The smallest gap where the bumper meets the fender..but always liked the product and will be buying another kit soon!

    I really like the body kit and it totally changed the look!! I only had time to install the front bumper for now. But I will eventually have the time to do the side skirts and spoiler. It probably took about 3 hours to install.

    ROUSH kit

    Great kit. Made to spec. The only thing that I'm not a fan of is using 3M tape to keep some of the parts attached to the car. I just don't like 3M tape. Other then that I couldn't be happier.

    great set up

    The Rousch Stage 3 body kit fit great. I had it professionally painted and installed, fit right the first time and looks like it came from the factory. Only reason this didn't get 5 stars was because I couldn't find the side exhaust system on American Muscles website so I had to go to a different supplier to complete the look.
