It feels like the rear end of my car is attached to the rest of the body now. I thought the reviews were fluff and the difference wouldn't be drastic. I was mistaken. A must have part.
So I installed these with the Beatrush Trans Mount, Rear Diff Inserts, Gearbox Positive Shift Kit and Whiteline Front and Rear Shifter Bushings. Thanks to these, the rear end feels much more planted and willing to turn in during corner entry while also feeling more responsive and cooperative. In daily use on rough roads, it hasn't increased the ride stiffness by a noticeable amount to me and I can gladly live with it as a daily despite the harsh roads here. NVH also hasn't increased by much. The only issue was that these were a bit of a pain to install but it was done in about 4 hours.
These only took me about 30 minutes to install on my 2011 STI. Stiffened up the rear quite a bit. Be sure to use a lot of grease inside and out or they will be squeaky.
I should have greased these up more, you should too. Paired with the Diff inserts, I could feel the rear wheels work. On a 14 wrx, stock suspension, you know its AWD but it tends to feel like FWD or like you are floating in between 4 wheels when pushing it in corners. With the bushings, you know where you are located and can feel the rear wheels actively gripping and providing power.
OMG these did wonders for the handling of my car. I installed these and then went up the Tail of the Dragon (featured on deadliest roads) and the car performed great around the corners. Such a differnce over stock. There is some added NVH mostly at WOT. But the trade off is definitely worth it. The install is super easy. Make sure you have a 14mm, 19mm and at least a 6inch extension. torque specs are 106.9 ft lbs for the 19mm bolts and 51.6 ft lbs for the 14mm bolts. Its a great buy well worth the money .

Q: 2011 Legacy 3.6R lettuce3.6R6 years ago
I know some WRX rear suspension parts are shared with the legacy 3.6R. Would this part fit on a legacy 3.6R? i have already installed the differential bushing inserts, the whiteline rear sway bar and kartboy endlinks and they work great, looking to stiffen up that rear end.

Q: 2011 WRX??? iglesiasm193301711 years ago
So it is confirmed this will work on 2011 WRX? I guess Whiteline had to make a new one for 2011-2012 since the bushings are different than 08-09...

A: You will need to lower the rear sub frame to install these inserts and that can be dangerous if you do not have the proper equipment. The install is fairly simple once you lower the rear sub frame.
