    I don't know if I've just tuned it out, but it seems to me that over the years the NVH has settled down quite a bit (this is referring to my experience doing everything but the motor mounts on the first USDM model).

    I'll definitely agree with you on hearing and feeling the mechanics. It's cool. You feel more connected. Hell...I hear so much vibration and rattling now since I did the diff mount bushings and subframe bushings...but I eliminated the loud clunk I got when shifting, so I don't care. Its much more worth it, and everything really is much more fun to drive since it's all buttoned up and solid now.
    Well I think I was just intimidated by the amount of things I was hoping to put on. I found mixed reviews on the degree of difficulty as far as the install, but it sounds like I may have missed an opportunity to get some wrench time in. Oh well, I'm loving everything more and more each day. The radio has still not been turned on... Next time I won't psych myself out!

    Hi, newb here.

    For those of you who have done the Group N motor mounts on a 2011+ WRX, how the hell did you manage to unbolt the rear 14mm bolt? I've been following these install guides on IWSTI (GR: How to install motor mounts - Subaru Impreza WRX STI Forums: IWSTI.com and Install Guide: STi Group-N Engine Mounts - Subaru Impreza WRX STI Forums: IWSTI.com), and the plastic brackets that come stock on the WRX are shaped such that the head of the 14 mm bolts are partially surrounded by plastic (whereas the steel brackets that come with the GroupNs are relatively thin and don't cover the bolt head); they can be reached with a ratchet/socket, but not with a flex-head box wrench. Has anyone else ran into this problem? I did manage to jack the engine up just enough to fit a short 14 mm socket onto it, but then the front axle left me no room to twist with.

    Besides the intercooler, pitch stop, air intake duct, and the two radiator brackets, what else would need to be removed (or preferably just loosened) to get the engine an inch or two higher?

    Also, assuming you did in fact only use a box wrench on the rear bolt, how did you torque it down to spec? There's no way you can torque that thing down to ~70 ft-lbs with a box wrench.

    I have a torque solutions pitch stop on my 11 wrx on stock motor mounts. I will let u know if they break....sure hope not. I am putting down 335wtq atm. Thx for the justification to the wife to upgrade! Lol

    Sounds like you shouldn't be using a box wrench.

    Don't know why you're getting sarcastic. It's good advice, don't use a wrench where a ratchet is needed, don't use a screwdriver for a pry bar, don't use pliers as a hammer, etc.... It's called using the right tool for the job, and it's why mechanics have so many tools.

    1) Getting sarcastic b/c dude was getting sarcastic with me
    2) Huge gap between pliers and a hammer bud. And a sarcastic comment about using the "wrong" tool is not what I would call advice. Point is, I might be a newb (which I clearly stated in the beginning of the post), but no need to be an *******
    3) Maybe not all of us are mechanics with a $10,000+ set of tools. Which is why I stated that, as a non-mechanic, I'm trying to use the guides that other people have taken the time to post for laymen like me. In both of these guides, they use a box wrench to get to the rear mount bolt, which is why I tried using said box wrench.

    Thank you both for your wonderful help. I'll go with the ratchet.
