Thanks

The hood project has just been put on hold until next season... however...



A carbon fiber rear diffuser will be the finishing touch for this season

It's from Shine Aero products and its friggin sweet. It weighs pretty much nothing and fits pretty nicely. I may or may not have to trim the rear of it, but we'll see. This will cover up the unsightly exhaust, and extend right to the rear of the subframe. I still need to bolt those "fins" on, they're just sitting there, but I love the business look of this thing. I've been waiting a long time to do this! I think Blacktree is the only other guy who has a tunnel style rear diffuser on his fiero!

Very, Very nice. That is a lot nicer than what I could do for you without a vacuum unit. It looks very nice with the thinner fins.

Thanks Adam. I'll take some pictures when I install it (a day or two). I have to figure out how I'm going to mount this thing. Might take a trip over to the home depot racing department lol.

Hood mod is going to look great and yes that's a great winter project...
I'll be watchin the diffuser mod since I can't visualize how it's going to look

Got the rear diffuser installed today!

I took some pictures of the installation.. first we have my work bench... the ground.. very comfortable:



Then I bolted up the fins to the diffuser tunnel... pretty easy, just drill some holes:



Next up, I decided that mounting it would be easiest with some flat stock aluminum. Its easy to drill, and light weight. My mounting locations are the rear cradle and the underside of the bumper. Get your measuring tape and measure out some dimensions for where to drill:



Here you can see my mounting points on the rear bumper. Ignore the old two sided tape residue from the old fins. I have to clean it:



Then mount the aluminum flat stock to the diffuser:



Mount up the front side, support the rear, and mark off the mounting points on the rear:



Then I removed everything to drill the mounting points in the rear. I also took some sheet metal and made a heat shield (muffler is close by) / deflector for air so that air doesnt hit the leading edge and go over the diffuser. I also had to trim about 3 inches off the back of the diffuser.



Reinstall and enjoy!







I still need to wash the car (remove the old two sided tape residue) and take some pictures from a distance. It was a rainy day and really dark out, a lot of pictures were turning out like crap.

Hope you guys like it! I do

Talk about a perfect fit. My biggest concern when we discussed it was the exhaust cutouts interfering with the diffuser. That one fits perfectly and is just the right size. Hell, I may have to buy one for myself

Edit to add....if you are concerned about the heat from the exhaust, you can always buy a few feet of the really thick fiberglass structural material on Ebay and just glue it on. That way no heat will make it through to the diffuser.

It was pretty close to perfect for the fit. I did have to trim about 3 inches off the rear. I could have left it on, but I didn't want the diffuser to extend too far.. I have a small oil leak from my oil pressure sending unit fitting, I didn't want the oil to puddle on the diffuser. I figured cutting it at the rear cross member of the subframe would be a good location.

Hopefully the sheet metal does a good job of deflecting some of the heat or even absorbing it a bit from the muffler. I don't want this thing to go up in flames! (knock on wood)

I test fitted a few other diffusers before I bought this one, but this seemed to fit the best with the least amount of cutting. If you're looking for one, try googling Shine diffusers.

I don't really like notchies, but this is without a doubt- my favorite one.. You've done an amazing job with the car.
JesseM AUG 24, 01:10 PM
I am very excited for you! The diffuser looks really good on that thing. I love the wrap around spoiler as well, it all flows well IMO. Let us know how the ride is affected now.
