OMGHi2U Confirmed Fitment: 2015+ WRX Transmission Crossmember Bushings

I finally got around to installing my Group-N transmission mount (got the 020 version) and figured I'd spend the extra $10 on a set of Energy Suspension transmission crossmember bushings to further tighten up the sloppy factory engine movement.

I can confirm that the 2008-2014 WRX transmission crossmember bushings DO in fact fit the 2015+ WRX. They are the same size and everything. From what research I've done, your options are:

-Turn in Concepts part # 1001-01-0025 (you WILL need to use the included spacer)
-Whiteline part # WHI KDT901
-Energy Suspension 19.1103G (black), 19.1103R (red)


Picture proof:

Factory bushings (towards front of vehicle):


Urethane bushings (sorry for inverted image):


Factory bushings (towards rear of vehicle):


Urethane bushings installed:


Installed (Front bushings):


Installed (rear bushings):




Installation Instructions / Tidbits:
Tools needed: Jack w/2 jackstand, 14mm deep socket & ratchet, 17mm socket.
1: Jack up front of car & secure on jackstands
2: Loosen 2x 14mm front transmission xmember bolts, 2x 14mm rear transmission xmember bolts, 2x 17mm front crossmember brace bolts
3: Remove the 2 14mm transmission mount nuts completely
4: Remove the 2 17mm front crossmember brace bolts and 2 14mm front xmember bushing bolts
5: Loosen the 2 rear 14mm xmember bushing bolts. You should be able to swing the arm down far enough to swap the front bushings out entirely. Both bushings are the smaller size ones. Secure the 2 14mm bolts back loosely.
6: Remove the rear 2 14mm xmember bushing bolts & install the LARGE bushing in between the braces and the small one in between the brace and sandwich plate (closer to you).
7: Reinstall all bolts & tighten 14mm bolts to 56 ft-lbs and 17mm bolts to 80 ft-lbs.
8: Lower car from jackstands....profit!

Impressions:
Since I installed both the group-N transmission mount and these bushings at the same time, I can't give a proper first impression but the combination of the two definitely makes a huge difference with how direct shifting is and how much the engine wobbles when starting out in 1st gear and accelerating. I still haven't installed my group-n pitchstop so my engine does still have some wobble but not nearly as much as it did before. I did NOT notice any additional NVH after installing both of these.

I took a video of me installing the bushings onto the brace with it off the car. I demonstrated how flimsy the factory rubber bushings are in comparison the the new ES ones. The factory ones can be folded in half with both fingers with very little effort. The ES ones can maybe fold 90 degrees if you squeeze ~5lbs of pressure on both ends. They are still pliable but not nearly as much as the stockers. I can't comment on durometers but I'd guess that the factory ones are under 40 durometer and the ES ones are around 70-80 durometer, comfirmation would be great.

I also did the whiteline positive shift bushings when I had the tranny mount installed. Also, rear diff bushings and beatrush prop shaft bushings and group N pitch stop mount.

Car feels great.

Next up is perrin engine mounts.

i finally got around to installing the group N pitch stop (along with verticooler/ egr&tgv deletes ) and holy crap! Way less drivetrain slop when shifting. Also, as weird as it sounds, the car actually feels more composed in corners. I noticed the same when I put all 4 group N mounts on my bugeye way back in the day also.

Hey Gro,

I think you can also include Group N STI Trans Crossmember Bushing Kit Part No. B4100FG000. I took your recommendation for the Energy Suspension part instead; for 1/3 price of anything else, why not?

Default My impression - just the group-N trans mount

I installed only the group-N trans mount and it removes the majority of the slop that was bothering me. I think it made a bigger difference on my old 02 bug eye, but still worth it on the 2015. No increase in NVH that I can tell.

-JL

Edit: I still just have the trans mount, but it's been in there over a week and I have several hundred miles on it now. I believe there is actually a slight increase in NVH. There's maybe a slight gear whine in some conditions (3rd gear at 25mph with no load). I don't remember this from before. Also a bit more engine noise when accelerating. Again this is minimal and is perfectly acceptable IMO. I took me a bit to even notice it.

Default B4100FG000 cross member bushings

Hey guys, I haven't posted in a while. I'm about to install the bushings with the group N mount. Do you grease these bushings before putting them in? And if so, where exactly do I put the grease and how much grease should be used? I've asked around other websites and I've been told so far that they do not require any grease, but I want to be sure. I don't want to take them out and reinstall them once they're in. Thanks

Sorry for the above, I think I just found a more appropriate thread for the above and posted this question there.

I used the black energy suspension bushings. The black ones have graphite impregnated in the bushing and don't require to be greased. The red energy suspension bushings require greasing. I didn't notice any real difference in noise from installing these with the group n transmission mount. The gear whine noise is present but I don't think that noise is from the group n transmission mount. When I installed the group n engine mounts together with the group n trans mount the gear whine noise actually quiet down/is almost gone.

Thanks. I installed the Group N bushings today, which are rubber, but much stiffer than stock. I ended up not greasing them since the factory ones I removed were bone dry. I figured if they didn't grease them, I won't. Drove it today and everything seems fine. Very happy with both the tranny mount and bushings. Good upgrade.
