C7 Rear spoiler
 

Has anyone added a rear spoiler that is applied with two-sided tape? Concerned about the longevity of the tape.

It will be fine. Double sided tape will hold it down. It will also lean against the third brake light. You can frequently check it by seeing if their is any separation. If so remove spoiler and apply new double sided tape. I’m guessing this tape will last 4 to 5 years.

I would not install a spoiler without some mechanical fasteners...
You don't HAVE to install all spoilers with fasteners....just the ones you want to keep..:)

Mine has been on with the tape for over a year and no issues. Just do good prep with alcohol wipe pad.

Depends on how fast you drive ... :yesnod:

Not a chance I would take. If you want a spoiler added do it 100% solid. Fast and easy has risks.

In the event you decide to do it the right way look at this video.

I guess you never tried to take a body side molding off, have you?
I applied mine with tape and adhesion promoter. It'll last on there longer than I'll be alive. If prepped right and done correctly, no problems at all.

Use the tape if that's what you decide, and sleep well knowing it ain't going anywhere. Some guys just over think things sometime.

There is quite a bit of difference in body side molding, which has essential no aerodynamic forces on it, staying on, and a spoiler that is designed to generate hundreds of pounds of force.
There are just some things that are not worth the risk of taking shortcuts. If GM could save some money using tape, and it was just as secure, they would be doing it. :yesnod:

:thumbs::thumbs: great stuff

Thanks, great video. I am considering the tape because I thought it would be pretty involved, now I know.

Agree, the "small" one looks very clean. Thanks for your reply.

It's down force. And the tape today is used in many automotive applications. Like I said, you're over thinking...:D

I would definitely look into using 3-M Automotive Adhesion PromoterAdvanced Auto was my source, it's a promoter after you clean the area, just before you put the spoiler on. Goggle 3-M Automotive Adhesion Promoter and view the how to films. The number, I used and was recommended was 3-M #06396. The problem will be finding someone who will sell the individual packs as you only need one or two at the most and they are $3.95 each Really makes the tape stick.

:iagree: This stuff will be on the car after you have sold it for sure. It only get better with time & heat from the sun bonding it more as if one piece..:thumbs: I really would hate to be the one to try & get it off the car... But get this stuff here all two side type is not the same... Robert

Hmm, TEXHAWKO is right. The Z51 spoiler creates 17% more drag than the base car! That downforce vector has a similar force pushing on the spoiler that causes the drag. My Stage 2 aero has even more downforce but has 33% more drag, primarily caused by the large wing extensions! The force pushing on the spoiler is even more! Now that rear diffuser I just added produces downforce with less added drag than the equivalent produced by a spoiler! :yesnod:

GM uses a lot of two side tape but thank goodness not on the spoiler! Also happy I have 13 rivets per side on my GM full length side skirts that come with the Stage 2 aero package.

Know some folks use tape but if like myself hitting redline in 3rd gear often would not want the OP seeing the spoiler in his mirror flying off on the Road! :lol:
