Just did this, you can really feel the difference. And for the price and ease why not ? Thanks import image racing for the video on this, didn’t even know about this mod
Great video. Like I mentioned in your other videos, can you please include bolt torque specs on your future videos? Some of us like to do more than "good n tight".
Being that this wrx chassis is on the global platform I think it would be great to see the rear subframe inserts install as detailed as this video if possible.
I'm no pro, but I would imagine if you did it as he does (one nut as a time) it shouldn't move too much. But you may need to use a jack to keep the diff in place when doing the carrier bushings.

Do you think these and the trans install you just did puts added stress thru the already weakish* trans. I figure the shock only happens once but is harder during hard shifts vs bouncing around causing continuous lighter shocks with the stock setup. Your thoughts?
This topic is largely debated on. Some people think that the sloppy stock mounts making the transmission move around more puts more stress on it and stiffer mounts keep it stationary and absorb the vibrations through the mounts (or through the chassis for aolid mounts) and other people will argue that it's the exact opposite. No one has directly linked either one to transmission or engine failure. People have been putting full solid mounts in drift cars, auto cross cars, and drag cars for years so I'm 100% positive if they caused issues people would know about it by now. Hope this helps.
@@ImportImageRacing thanx for taking the time out to ask. Im maxed out on my understanding of physics here. It sounds like if anything negative, its a trade off which is pretty much what modding a car is. Again thanx
@@ImportImageRacing you guys literally have answered all my questions and quickly. Thank you for all you guys and gals do. My '22 Magnetite Gray should be here next month!
I love how they are just sticking on anything that fits on this car from the old chassis. Development for these is gonna be slow given all the tuning drama
We are for sure installing anything that fits. No harm in showing people the things they can do to the car while they wait for new parts to be developed. The tuning drama probably isn't slowing down any development. It's the fact that so much changed from the last chassis to this one that everything is new and needs completely redesigned.
We currently have 24 of the whiteline kit in stock. Same exact kit just a different brand name. www.importimageracing.com/products/kdt903-whiteline-rear-differential-mount-inserts-wrx-sti-2008-2021-forester-xt-2009-2017
If anything, the casing would have some damages but the insides should be just fine. You can always pop the differential cover off to see if there's any sorts of damages.
@@daneyoung7770 Thanks for the reply, everything ended up being okay, the U bracket just got cought on its own threads and caused everthing to drop at once but the actual bang was the U bracket itself.
There are definitely options, but as far as stiffening goes, doing something like the Group N trans mount or Kein trans mount would be excellent. Pair that with the Perrin Pitch Stop and you're good!
That was mentioned towards the end of the video but these combined with the upgraded transmission mount added a very small amount of noise but it's only noticeable when driving with the windows up and no music or anything playing. It's not bad at all! Hope this helps!
Correct. Usually people worry about hearing more vibrations, gear chatter, or transmission whine with these types of inserts and mounts. With these you hear a very faint whine if you have all the windows up and the music off. But we also have the transmission mount, pitch stop and these inserts. Its very subtle!
It's a pretty quiet car so I can't imagine there would be anything additive that would be so awful. Then again I traded a BRZ in for my WRX, so I'm probably legally deaf after six years of driving that car.
@@sethiousbell82 Not more than is already there. It was a very tasteful few modifications that helped firm up a lot of slop! I didn't notice any extra NVH
To be completely hoenst with you, the only bolts on this car ive ever considered or heard of being one time use are head studs. I've never Torqued a bolt to spec besides on internal engine components, clutch/ Flywheel and crucial suspension components and have yet to have an issue in my 10 years of modifying cars. I'm sure Theres a Torque spec for every single bolt on the car somewhere if someone wants to find it.

Does the 22 use the same r160 differential? Asking because I am thinking about upgrading the rear dif with a LSD.
Why is only one side solid anyway?
Please also install rear subframe inserts!!! 🙏
Being that this wrx chassis is on the global platform I think it would be great to see the rear subframe inserts install as detailed as this video if possible.
Just got mine in the mail. Do you know the various torque specs?
50 ft.lbs should get the job done :)
Are you going to put bushings on the other side? Seems to be uneven now won't it affect the differential?
It is strange but this is how it's designed so it won't cause any issues!
@@ImportImageRacing why not both side ..?
What make and model quick jack are you guys using? Looking to buy the same one to work on my 2022 wrx
Quick jack 5000EXT
Can you do this on ramps? Or do the wheels need to have no weight on them?
I'm no pro, but I would imagine if you did it as he does (one nut as a time) it shouldn't move too much. But you may need to use a jack to keep the diff in place when doing the carrier bushings.
@@CasprCo. I did it on ramps. And used my shoulder to pop the diff
Where did you guys get the red badges from? I’ve checked a few sites and nothing for the 22 yet. Unless the 15-21 WRX badges are the same size?

Off topic. The tire repair kit in the trunk that replaced the spare. Does it have an electric pump as well to get the tire up to pressure?
Yep! There's a small electric pump in the kit!

should we use some king of grease to revent squeaking?
Dielectric grease
the inserts come with grease
Does this fit a Ford Prius?
No i've never seen a ford prius haha
@@ImportImageRacing Thanks for the response! On a serious note, will these install on a ‘23 Outback?
@@w00tplayaw00t They have not been tested on that year/model car to confirm :(
Do u guys know when u going to have back on stock.if not I’m gonna cancel my order
We currently have 24 of the whiteline kit in stock. Same exact kit just a different brand name. www.importimageracing.com/products/kdt903-whiteline-rear-differential-mount-inserts-wrx-sti-2008-2021-forester-xt-2009-2017
Do they perform the same? And It’s there any way that my order can be change?
Should the bolts be torqued to a certain spec after install?
Factory torque is 51.6 ft lbs if you're worried about it.
@@ImportImageRacing thank you! I'm usually not worried but this is going on my wife's daily. She would kill me if it squeeked.
I followed this guide exactly but I was on ramps and the diff drooped and made a really bad noise. Anyone know if I messed up bad?
If anything, the casing would have some damages but the insides should be just fine. You can always pop the differential cover off to see if there's any sorts of damages.
@@daneyoung7770 Thanks for the reply, everything ended up being okay, the U bracket just got cought on its own threads and caused everthing to drop at once but the actual bang was the U bracket itself.
After break in it will be great.
After they start to break in they tend to get really sloppy haha
@@ImportImageRacing true 🤣
What about the front? Anything to do there?
There are definitely options, but as far as stiffening goes, doing something like the Group N trans mount or Kein trans mount would be excellent. Pair that with the Perrin Pitch Stop and you're good!
Would this make a noticeable change on the auto?
That was mentioned towards the end of the video but these combined with the upgraded transmission mount added a very small amount of noise but it's only noticeable when driving with the windows up and no music or anything playing. It's not bad at all! Hope this helps!
@@ImportImageRacing yep I heard, I just never understood the actual intention as to what this is for and I know the auto has a different AWD setup
Whats the torque specs?
Rear Diff inserts

What kinda noise? Transmission whine?
Correct. Usually people worry about hearing more vibrations, gear chatter, or transmission whine with these types of inserts and mounts. With these you hear a very faint whine if you have all the windows up and the music off. But we also have the transmission mount, pitch stop and these inserts. Its very subtle!
@@ImportImageRacing great, I enjoy that sound. Just ordered them.
It's a pretty quiet car so I can't imagine there would be anything additive that would be so awful. Then again I traded a BRZ in for my WRX, so I'm probably legally deaf after six years of driving that car.
@@ImportImageRacingDid you guys hear any gear chatter after installing group n mount, pitch stop, rear diff inserts, positive shift kit?
@@sethiousbell82 Not more than is already there. It was a very tasteful few modifications that helped firm up a lot of slop! I didn't notice any extra NVH
Are any of the bolts one time use stretch bolts? Glad you had all of the torque specs memorized.
To be completely hoenst with you, the only bolts on this car ive ever considered or heard of being one time use are head studs.

@@ImportImageRacing😂😂
That’s nice. The washer should be made of stainless steel. That one isn’t.
Thank you for your comment
why make it stiffer it rides hard now
This doesn't impact the suspension or the ride quality.
When are we gonna make these things RWD!?!?!?
BRZ or DCCD?
