I'm checking on those other 4 at powdercoat today.

Any idea on how low it hangs down? Just want to make sure I'll be able to clear it with how low I am.

The fit and finish of the diffuser are perfect and I'm really happy with it. I really like the slotted adjustments at the rear sway bar mounts and at the back where it attaches to the lower bumper cover. The slotted swaybar mounts allow for fitment with bigger mufflers and/or more aggressive angles of attack. I installed mine pushed all the way up and I still have plenty of clearance with my OEM midpipe and WORKS AB-M axleback.

My only gripes would be with the shipping. The box was plenty rigid but it didn't have enough packing material IMO. There was some, but not enough soft cardboard-derived fabric material in there that may have originally surrounded the diffuser but my box arrived standing tall and the fabric was all bunched up at the bottom. When I unpacked the diffuser the fin on the very end on the driver's side was bent inwards because it had all the weight on it when the box was positioned upright and I had to carefully bend it back straight; easy to do since it's aluminum. I immediately thought that injection foam, while a more expensive packing material, would definitely be worth paying for as it would contour to the awkward shape and keep it from shifting around so much when the box is handled.

When you get more please have a black one in a "kit form" (verticals not attached) made and let me know the cost.

Thanks again!!!

Thank you! I don't know about the foam but I will definitely make sure I'm packing these suckers up better.

I will make sure I have a better solution. My apologies for messing it up.

Any review on this, functional?

I have reports and photos of highway cruise mpg hitting 39 on the dash readout, I personally experienced an mpg increase on highway cruise; which would indicate yes. I built it to be functional. I cannot claim mpg increase as factual data as it varies greatly.

I'm working on getting actual aero data, I should be getting feedback on that shortly.

@Wonderbar you know I'm a geek for this stuff, and I've been thinking up different designs, so I wanted to bounce a question off you. Have you installed a GoPro to watch the diffuser at speed? in particular, flutter of the leading edge, where the mount tabs attach to the RARB bolts? That should be the area of lowest pressure.

I have not. However, I will give it a go this weekend. Want to drive up this way and give a hand?

The reason y I asked,because last time I bought a voltex copy diffuser and it pulled my whole Bumper off after I ran up 100ml free way. And I don't want it happen to this car. And if there is track review will be nice

The "main drag" edge of my diffuser mounts to the frame of the car. I have put thousands of highway miles on mine with no issues. I have several people catching up to me on miles.

@FT-86 SpeedFactory has theirs on the track every other week!
