Rear Diff Bushings from TiC

I bought these bushings from RallySportDirect.com:

Here's the review:
I was blown away by how much this effected the car. First off, yes. It makes your drivetrain feel much more connected to the car. It's so much more than that though. When you hit a bump, the force will go through the car much more quickly instead of shaking your drivetrain around for a second or two. Engaging each gear is far smoother as well as the drivetrain does not squirm under the torque (I have an upgraded STi). The "Subaru thud" is removed. I had it so loud that when I passed other cars, they would tell me later that it sounded like something broke. This improved the handling feel of the car as well. Any kind of bumpy road used to be a shaky rollercoaster ride. Now the force is translated much more directly. It's like sharper, harder, bursts but in between the car feels locked to the road and smooth. This part is stiff and not for everyone but the improvement is staggering.
