Just received my lip today and was wondering how long it usually takes to install. Also if you have to remove the bumper or you can do it with it on the car?

 

Bump?... been wondering this too

 

It will probably take more time removing and installing the bumper.
I'm not exactly sure if the JDP lip uses bolts. The lip on my evo 8 had maybe 10 bolts as well as double sided tape. I actually used RTV black sealant on the lip and the bumper.

The lip never came off even hitting dips and things.

Should be 1 hour tops. (I can take the bumper off in 10 minutes)

 

Try duck tape and jb weld lol jk
