The website says, "all necessary clips and bolts for install". Which I found not to be true.
Jason or Jeff let me know if the bolts and nuts were missing from my package.
I did a test drive last night and there was a difference at 120kph / 85mph. I could feel the rear of the car. The difference could be greater because I have Nismo S-tune exhaust which does NOT have the stock 350Z exhaust deflector. I am not sure if this is due to lower drag or less lift or both. The rear of the car is deffinitely connected to the rest of the car at that speed. I never felt that the Z was loose in the rear at 85mph before this mod.

I have PDF'd this guide for everyone's convenience; please right click here, and choose Save To Disk.
Btw I'm heading out to Home Depot now to buy the necessary M6 bolts and washers and will try to perform the install using this guide; once it's in, I'll give it a quick spin to see if I can tell any difference.

I used the guide to install the diffusers earlier. The guide definitely is accurate; the kit does not include the necessary nuts for the studs on the driver's side, nor does it include washers, so indeed you will need to make a quick trip to the hardware store to pick some up.
I didn't get a chance to really push it (with eight points on my license, I can't really risk it), but I did take it up to 90 and indeed the rear feels a little more buttoned-down. Main thing I noticed was less wind noise from the back underneath, so it's definitely doing something.

Old thread, but for all too lazy to actually scour the parts diagram...

What's the difference between the two? One is left side and one is right side?
