Long Skinny Arms Needed
I have been wanting this rear diffuser for quite some time and finally sprang for it. It took probably 20 minutes or more to unpack, but that’s a good thing. Initially it seemed it would be an easy install. But as I got to the rear screws that’s when easy went away. Getting the nut on the left rear screw was a major pain. Luckily I have the Roadster Sport Race muffler installed so that provided just enough gap for me to stick my arm in and reach over. This is where long skinny arms come in. If you have twin exhaust pipes coming out - good luck. Without the factory diffuser it may be easier as there is a gap there. Overall it took a couple of hours and for the most part an easy install. And, the aggressive look is worth it as well. If I could change anything, it would be to replace the allen head screws with hex head bolts for the front and side mounting locations. There is a good install video on YouTube that is worth watching.
