I worried about scraping, but I've had it installed now for about 1500 miles and to date have never bottomed out. It seem like I get less noise from under the car at higher speeds over say 60-70 MPH...Maybe less air turbulance...As far as stability, I have no idea, I bought it cuz I thought it looked AWESOME. Oh and Glenn with Difflow is a great guy, easy to work with, and very prompt with deliveries.

Saturday a Difflow railer arrived and I was very impressed with the quality. Installation was a snap, and it matched up perfectly. Most excellent!!!!

LOVE IT!

Installation: Installation really requires an extra person to help you adjust the alignment, so, get a patience girlfriend, a good friend and take your 30-40 minutes to install, if you do again it will take you like 10min, is just the first time takes time to get it right.

I have chosen to drill 2 holes on my valance as you can see on my 7th pic, I also added a strip of double side tape, but man, once you attach the front last bracket, this thing is not going ANYWHERE, I am just a bit paranoid.

Quality: SOLID and impressive and it looks very aggressive and doesn't look CHEAP quite the opposite.

Lowered NSX's: Guys with lowered NSX's … very lowered cars like mine might have problems in some estates, we did scrape a bit last night, I was certain that I was going to raise my car on the rear by .25 but after all day driving today around town, I realized is fine, I am also used to get in angles in and out inclines.

Looks: The diffuser goes "OUT" on the back -as you can see on my pic- .. I got shocked in the beginning then took me 5 seconds to get used, now, I actually LOVE IT since it flushes with the top part of our rear bumper.

Regrets: NONE

Recommended?: Absolutely, if you NSX is cleanly modded but you want some extra "spice" on the rear, GO AHEAD!

Quality vs the DF big rear diffuser: Don't get me wrong, I love the DF rear diffuser, I have both and of I had to chose I'll just chose difflow 100% … seems more functional, and it is a lot better quality since is made of aluminum, also the way that is installed is so much better.

My day at Summit Point started out VERY wet. In fact, it was practically a monsoon on the way there and for the first 20 minute track session, so speeds were cut in half due to reduced traction. Someone following me in a Porsche did comment on how interesting the water looking coming out from under the diffuser, stating it was split into 6 channels and really looked neat! Maybe that's a good way to visualize the airflow? I did seem to "feel" a slight difference on the longest straight just before turn 1, which is the fastest part of the track. I tend to reach speeds upwards of 130+ and the rear end of the car felt slightly more "planted". Usually, the car starts to feel a bit light or gives me a feeling like the rear end wants to float based on the air pressure, but the diffuser did alleviate that for me.
