Verus rear diffuser for ND

After switching from the stock exhaust system to the Goodwin race exhaust, I noticed a feeling of drag in the car at highway speeds. The Goodwin race exhaust is much smaller than the stock system and leaves a rather large pocket for air to collect in. After installing, I really can feel a difference at 65+ miles an hour. It may be placebo, but im happy with the results.

Install was not technically difficult. I have very little experience with working on cars and was able to do it in an hour. Instructions were pretty clear and there are many videos online of people installing this part. My only recommendation that should really be required is to tighten down the bolts holding the rear sway bar BEFORE bolting the diffuser onto the car. It might lead to a less perfect level, but once the diffuser is installed its very hard to reach these bolts to tighten them. Other than that, quite a few of the bolts are a bit hard to reach, but its manageable.

Again, with a smaller exhaust this diffuser makes a difference in my opition. I installed the diffuser at the highest level and am really happy with the look of it.

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.

Do yourself a favor and install M6 rivet nuts on the brackets that hold the rear of the diffuser, where the spacers are used.
This will make install and maintenance removals infinitely easier. Without rivnuts, I don't know how you can install this with anything but the thickest spacers which are less than ideal for the aerodynamic effect this is supposed to provide.

Otherwise, this piece is very nicely made with great fit/finish. Instructions are clear.

When used in combination with the Verus canards/dive plans, I found the car to be more planted at high speeds. Additionally, I could maintain a 36+MPG average (infotainment indicated, not hand calculated) with the top down while cruising ~75MPH.

Above all else, it looks great. Can't install aero parts if they don't make you look like the coolest kid in school, right?

The piece itself is very cool and well made. The hardware leaves much to be desired. For the money, the hardware should be of higher quality and easier for the install.

The quality is very nice. Make sure you have all of the parts before you start the install process. I was missing all 4 mounting brackets. I am pretty handy and I got it completed in about 90 minutes. You definately need a second set of hands to hang the diffuser once the mounting brackets are installed. Overall, I am very happy with the product.
