CarbonSignal Diffuser Installed

122554 · 08-18-2013, 11:57 AM

After traveling the last two weeks, I finally was able to install the diffuser I brought back from Dubai.

A few things about the install. I used 3M 5952 tape to secure it to the original bumper. Due to humid conditions, I found a heat gun indispensable for helping to use the silicone glue along the upper edge. As you can see in the pics, 2x4's also helped!

Just because I didn't know how well everything would hold, I found some flathead bolts at Lowe's and installed them at both corners on the bottom.

UPDATE

The silicone glue did not hold! After trying another product that also failed, I think I found the solution, after talking to a local body shop.

I used 3M 08609 Windshield adhesive. Picked it up at CarQuest, but it ain't cheap! $30 a tube. I ran a bead along the top edge. Used most of the tube. Clean up wasn't too bad, denatured alcohol and a roll of paper towels.

After it set up, I re-installed the two bolts I had previously placed at the lower corners.

So far, so good!

What kind of silicon did you use? i am awaiting some items from CarbonSignal and was wondering how to install properly.

Yea, that silicone Idea they told me scared me away from this product as I run my car on the track. You don't want parts flying off there.

Glad you got something that's working for you now.

Good job on the install. Carbon Signal makes good stuff.

Since you also used screws, surprised the silicon would not hold the diffuser tight enough.

There is a marine silicone that is 100% permanent to remove u have to scrape off or burn basically. I used to use it on my boat bought it at west marine.havent found anything stronger yet

I know this thread is super old, but I just bought the Nismo V1 rear diffuser and wanted some clarification on where exactly the bolts went and if the diffuser is still holding up after all these years?
I don't want to drill holes unless I absolutely have to, but I also don't want this thing falling off in a year. OP's inbox is full so if anyone else has had experience with this I'd appreciate all the input for what worked for you.
