SuperPro 2013 Scion FR-S Base Rear Upper Forward Differential Pinion Mount Bushing Set

If you're looking to tighten up the rear end of your 2013-2020 Subaru BRZ, especially if you notice slop or imprecise response when getting on and off the throttle, replacing the differential pinion mount bushings is a smart move. The factory rubber bushings are known to wear out relatively quickly, especially with harder driving, leading to more differential movement under load. This can manifest as a sluggish feel, secondary movements, and even noise and vibration as they degrade.

SuperPro's SPF4110-90K set replaces those worn factory bushings with a well-built polyurethane material designed to hold up better over time. These bushings help keep the differential located more accurately during acceleration and deceleration, giving you a more direct and responsive feel from the rear of the car. Importantly, SuperPro has engineered these to maintain a comfortable level of noise, vibration, and harshness isolation, so you don't sacrifice daily comfort for improved performance. You get a more solid connection to the road and a longer-lasting part compared to the original rubber.
