I have the VRS type 2 which is an easier install than type 1.
Honestly, the 3M tape does not hold it up at all. A member here, installed with 3M and the bolts. It eventually starts to peel away and gap, looks like crap. Another friend of mine had WagonWorks do it and it looks great. No gapping at all. The only true way is to urethane it on the back bumper with no gap. Honestly, it is not worth trying to save a little bit of money, rather than letting a body shop do it right the first time.
