These bushings were super easy to install and really tighten up the rear end of the FRS/BRZ platform! They add some NVH to the interior, but I installed these bushings at the same time as the transmission mount insert and I speculate that most of the NVH came from that.
I did add some white lithium grease to the bushings to help them slide in easier, as no grease is provided. additionally, the black machined 'washers' that go over the bushings look great, very stealthy.
Overall very happy with these bushings!
