Just wondering if these essentially are the same thing? If so which one is the better option to get rid of my CLUNK on every down shift in my MR.

Torque Solution urethane differential mount inserts $50


OR

Beatrush rear differential spacer $73




Also thinking about tossing these on as well... but not sure if it will make much of a difference... Just really trying to get rid of the hard clunk every time I make a shift in any mode other than Auto/Normal in my MR. Even in Auto/Normal mode it does it when I am on the highway and go to pass and it is getting very annoying and seems to be getting worse.

Torque solution drive shaft carrier bearing support bushings

 

Beatrush rear differential spacers + Torque Solutions driveshaft bushings is my recommended setup. It's perfect for street cars and very quick/easy to install.

 

Just dont do the Solid rear diff mount bushing.... makes diff whine at 75mph. But def get what kracka suggested. Makes the drive train feel more solid when shifting.

 

What exactly do the rear diff spacers do? And how do you feel about the beatrush driveshaft bushings compared to the torque solutions ones?

 

Beatrush rear diff spacers hold the differential more solidly in place to prevent it from flopping around during power transition. The spacers do not require the stock bushing to be pressed out which makes installation very quick and easy.

I had the Beatrush driveshaft bushings on my IX and the TS ones on my X. Both aluminum, but different colors, otherwise identical in fitment. TS has now switched to delrin instead of aluminum though. My honest opinion is buy whichever is cheaper (Torque Solutions).

 

So with the TS differential mounts I would have to press the OEMs out and have these pressed in? Wont there still be the movement from the OEM bushings with the Beatrush spacers? you still have them OEM ones in there to flex around...

 

If you get the ts bushings, you have to press Oem out. The new ones just set in there. The pics don't show the big washers that go on.

 

Go w/ TS ones, for Beatrush you're paying for the name…they're both a hard substance that prevents the diff from moving as much when you're rippin n tearin. I have the TS ones and it took me about an hour to put them in

 

PM'd sir

 

I did the beatrush rear diff spacers and the TS driveshaft bushings....pretty happy with them.

More of an annoying install then anything. Plus i ****ed up my rear diff bolt threads, the big *** bolt. It's in there solid but all cross threaded. Just make sure to support the rear diff when reinstalling. Both installs are straight forward and now my 600whp shifts don't have a giant clunk from the rear diff...seems to have worked for me.

 

Dont mean to thread jack or anything... But...


Is there a DIY install on these 2 items since I'm considering picking them up too

 

Really straight forward install. Biggest thing is having the Oem rear diff bushing pressed out. Other than that, make sure diff is supported and really easy after that.

 

Yes, there will still be a little flex from the OEM bushings, this is a good thing. The driveshaft and axles will still have movement so you want everything to have a little give to it. Locking it down solid is ok for a racecar, but not on a street car that's meant to stay reliable for a long time. The OEM bushings will soak up some of the initial shock, plus absorb the gear whine noise from the rear diff keeping everything more civilized.
The driveshaft bushings and Beatrush rear diff spacers are very easy to install, and will be very straight forward. Beatrush includes instructions in Japanese, but the pictures are all you need to look at to get the point. TS does not include instructions for the driveshaft bushings, but the larger bushing goes in from the bottom and the collar ring goes over that bushing from above.

 

There's a DIY for the TS ones online but it's easy to do

 

I think this will be my next mod. I hate that our stock set up gets floppy at times
