If it wasn't for ClovisLotus I wouldn't totally forgot about this thread. Anyway, I wasn't able to test it at the Nurburgring prior to returning stateside but on the autobahn the diffuser worked like a charm with the car feeling stable on straights up to 140mph and planted on bends up 130mph (both cases due to catching up to traffic). On normal winding roads I noticed a slight increase in stability, but nothing significant. My aero currently consists of the diffuser, the ZSpeed front undertray and modified Aimgain canards, so yours being a bit more involved with a front splitter and rear GT wing, the diffuser would obviously be more beneficial.

I haven't taken many of the diffuser, however if there are any specific angles you'd like to see let me know and I can take some.

The current limiting factor on mine are the mufflers on the FI exhaust. For an exhaust similar to the Motordyne, or one of the OEM-styled ones where they tuck higher up into the bumper, I'm sure you'd be able to raise it quite a bit more. I'm debating selling mine with the FI exhaust so that I can pick up another diffuser with an E370, Garageline or Invidia so that it fits properly. Another thing I failed to mention previously was that due to our rear bumper being longer, the diffuser doesn't stick out as far as it is intended when used with the Base/Sport bumper; however, it does still flow naturally with the "diffuser" area of the Nismo bumper albeit unintentionally.

LOL, I was cracking because of the same thing and I figured you just forgot. Anyway, thanks for the information and glad to hear that your review is positive. I have not had mine mounted yet but have something in the works. I am having a rear diff cooler installed so I don't no if that will be a significant problem as well. I will post up here on the outcome.

Bobby, you will have to cut a hole in the diffuser for air flow to the diff cooler.

My initial reaction is the same as yours. I sent the photos you posted to Fast Intentions as Tony will be doing the install of the diffuser. The diff cooler shipped today to Specialty Z for installation. I prepared for that diffuser not working at all. If that happens it back to the drawing board. I love this chit as it is all about the journey!

Just catching this thread...and did read through...but had a couple of clarifying questions:

Approx how much time does it take to install?
Pain factor of installing?
Can anyone confirm no issues with Motordyne E370 exhaust.

I am looking to purchase only for track use....is it really worth it?

I don't have a clue on the fitment with Motordyne but it does look like will work. The reason for most the conversation and why some of us took a chance with this diffuser is its functionality. After, I received mine and looking at how it should fit, I am convinced it will perform as advertised and that is why I'm taking significant measure to make it work.

So long as you don't need to modify anything, it can be installed within an hour.
Easy install.
It will fit the Motordyne without modification.

Any issues with ground clearance or bottoming out...going into driveways, trailer ramps, etc?

Steeles350 · 06-10-2018, 10:03 PM

no worse than any other part of the car. with the fast intentions exhaust the mufflers actually sit below the diffuser so they are at more risk than the diffuser. backing in and out of driveways is a little suspect. I need to crawl under mine and look since i've been house hunting and taking the z to make sure i can get in and out of driveways

much to my wifes chagrin

For folks who also had a diff cooler, how did you end up modifying your diffusers?
