I own a 2012 wrx sedan, and I was considering taking out the stock TMIC, for a FMIC. Heres why:
First off, I am going to end up doing some serious modifying to my car, and obviously a FMIC can potentially leave more room for HP.
Also, I was thinking about maybe instead just getting an upgraded top mount, but I hear it might waste money due to possibly more serious upgrading in the future.
Also though, I am slightly worried about it. How significantly turbo spool is affected, the fitment on the bumper, having to cut a bumper beam.
If anyone has any experience with this upgrade, it would be appreciated to give me your opinion.
