        It’s gonna come right off at speed

        I don’t what to say other then this product is not intended for a moving car.. as soon as you reach speeds above 80 it’s gonna tear itself apart... it does not get bolted on it’s actually held on by clips... the center piece is the first thing that’s gonna fly right off... they don’t tell you this. Avoid this product unless you’re willing to throw money away

        Nice Upgrade

        Bought the RTR Rear Splitter at the same time as the GT500 Rear diffuser. Simple to install but will take some time as there are many steps. This part adds an aggressive look, well worth the money. AM is the best

        complete the look

        definately a little pricey but its pretty durable material, I suggest same as previous review that bolts are better and feel sturdier than the push pins supplied, easy 30 minute install backed up on ramps

        Rtr rear splitter kit

        Was very simple to install, the only thing is the color and texture of the splitters do not match the diffuser at all. Before installing I painted them quick with textured black spray paint and the match is spot on. You may want to also use nuts-bolts and washers to affix the rear splitter as the scrivet style push pins will not hold that on there for long.

        RTR Rear 3pc Splitter Upgrade - 2013 Mustang

        I brought this product solely for the use of the rear diffuser splitter because I already have the Roush side and rear side splitter installed. I have the 2013 Mustang- Ford CS/Boss rear diffuser mounted on my GT. Though the fit of the RTR rear splitter fit is not perfect the difference is unnoticeable as its a matter of realignment/drilling of mounting holes. I used flat black plasti-dip on the RTR rear diffuser splitter to the Roush and Ford parts to match to match color and texture.
