I drilled a hole in the front stuck it under the wheel well and connected it. I drill 2 holes on the lip under the car.(one at both ends) and A LOT of double sided trim tape. I also used a heat gun to get them nice and sticky, since its about 29 degress in michigan. I know a lot of people have problems with taping them on. But if you do it right it shouldn't come off. Also I dont drive my Z much, so I shouldn't have any problems.
