I'd really like to get solid or stiffer transmission mounts/supports because the whine I've heard in some youtube videos is really appealing to me. My question is: Are there any risks in adding a solid transmission mount without installing anything else? I've read in other places that the housing or casing might break, but that was in a forum for a different car. I'm also strongly considering getting the STI engine mounts as well. Any feedback is appreciated and pardon me if there is already a thread with this information, as I'm not very good at navigating forums.
