Torque Solution Rear Differential Inserts Subaru WRX 08-23 / STI 08-21 | TS-SU-092

Interesting results. Acceleration is better now. Guessing just less parasitic loss from the driveline resulting in more available torque to the wheels.

Cheap easy mod. What are your waiting for?

My bushings came in a little rough, like a mouse was nibbling on it. Little annoyed by that but doesn't effect functionality.

Easy to install and did it while I was installing other parts under the car. Along with my other mods the car feels tighter and there seems to be less movement when putting down power.

Only needed the two bushings since I replaced the whole diff carrier for a cusco one. Install was super easy done in about 10 mins. The difference it makes alongside with a solid diff carrier is much better and definitely worth it as now it feels the rear is stiffened up from some slack.

Working well!

Perfect fit easily. Just raise diff so it’s even not squishing bushing.

Added these along with the group n pitch stop and trans mount. Seems to put more power down with much increase in NVH

Nice to have on the car. Makes it feel stiffer

I installed these with the billet rear diff brace. Fits perfectly

Half of the inserts and both metal washers fit 2023 wrx but the other two plastic inserts awkwardly go on the same side of the rear diff and I decided not to install once I saw this. Mixed bag IMO.

Parts went in fairly easy, its a good idea to look at some YouTube videos to see the way others have installed these parts. I believe between this and the Type N trans mount the drivetrain feels more lashed down!
