It's just double sided tape.
Can be done within 5min.

 

Okay wow. I might have to do this now

 

Remove tape backing put on top of trunk and push down

 

Has anyone ever had a problem with these falling off?

Mine came in yesterday and looks beautiful but probably won't get a chance to install until next week when I can wash the car and it is a little warmer out.

 

Dumb question, will these stay on if you go through an automatic car wash?

 

^ yes they would... the tape that they got on there is pretty strong or it should be strong. Gone through them a few times and still there. Had mine on for over 5 yrs now...

 

The tape is legit, it will not come off...

FYI- I ordered mine 1170mm and it is just a little too long, I am probably the only one who notices.. Possible the vendor mis-measured or that I just laid it in the slightly wrong spot.. it over hangs on one side.

BUT best $30 mod to date... Wish I did it sooner, I love it! and the paint color is dead on!

 

i ordered mine about 2 weeks ago and it came in this morning. when i got off tonite i decided to go ahead and highspeed the top of my trunk. i plugged in my da and got out a few pads and polishes. i started with the wool pad and rubbing compound. i removed the scratches that i could see and then moved on to some swirl remover. after the swirl remover i used some polish to finish it off.

i layed the spoiler out on the trunk and used tape to line it up as perfectly as i could. i did it in sections about 6" at a time. i used a hair dryer to heat the spoiler so i could bend it to the shape i needed. once i felt it was as perfect as i could get it i peeled the tape from one end of the spoiler and pressed down as i pulled the tape. once all the tape was off i took the hairdryer and heated the spoiler in sections until i got the whole thing warm and took a towel and pressed down hard and moved from one end to the other. here's the outcome. comments welcome.

 

^ looks good. Nice job on the extra prep

 

Looks great...I just ordered one for my coupe; planning on installing mine soon...

 

you won't be disappointed. just take the time to do it right the first time. there should be a sticky thread for these spoilers. so many people have them.

 

Here is mine after finally getting a chance to wash the car and put it on last night.
