Torque Solution Rear Subframe Inserts (Race Version) - Toyota 86 / FR-S / GR86 | Subaru BRZ

Going through the hassle of solid subframe bushings is really not worth it on most builds. It increases drivetrain shock by putting every little bit of force on your transmission, diff, and axles. A little movement is actually good for forward bite and of course, to absorb vibration. Decreased NVH helps too.
