Okay so i just installed a prodrive lip on my wrx but it still sags down. I tried putting double-sided tape but it's not staying up. Does anyone have any advice or trick to making this lip stay up on my car? thanks!

 

screw em in

 

i did screw in both side and bottom of the lip to the bumper but the front part is still sagging which i taped double-sided tape but it's not helping

 

I use nylon rivets in the front to help the d-s tape. The tape alone will not hold in the middle it needs support by either screws or nylon rivets.

 

Ok thanks for the advice guys! i just finished drilling a hole on both sides and screwed in with two screws! and now it looks way better!
