You'd better post pics of that if you do. The proper ones I've seen are very permanent sealing off the trunk.I had pretty good results in my 2015 WRX going IB. I have an IDMAX12 I'm not using but I think I'll get another one and end up going IB. It's not that permanent of an install actually, in the last WRX I had, I was able to get everything back to stock pretty easy before I traded it in.
