Before buying these, I had already installed a Group N tranny mount, super pro transmission crossmember bushing kit, shifter bushings, and a few other drivetrain/chassis goodies, so I wasn't sure how much of a difference this kit would make (2020 STI). After the install and a test drive, I was blown away. The 'slop' taking off from a stop and between shifts is essentially gone. I'm sure the other stuff I have on the car help, but this kit made a huge difference and complemented the other upgrades extraordinarily well. Considering the price, results, and ease of install, this is absolutely a must have.

Great product that stiffens up the rear end and keeps things nice and tight. It adds very little NVH and really makes the total package come together. I purchased this along with the trans bushings and I'm completely satisfied with the set up. If you want a nice positive firm feeling in the drive train this is a MUST have.
