Cobb 08-21 Subaru WRX & STI/2018 Type RA/2019 S209 Rear Differential Subframe Mount Bushing Inserts

With this kit, you get a set of two rear differential subframe mount bushing inserts. These are designed to stiffen up the rear end of your Subaru WRX or STI, including the 2018 Type RA and 2019 S209 models. By filling the voids in the factory rubber bushings, these inserts limit the unwanted movement of the rear differential under load.

When you're driving hard, especially during acceleration or cornering, the rear differential can shift around quite a bit. This movement can lead to a vague feeling in the rear of the car and can affect how precisely it handles. These COBB inserts are made from a durable polyurethane material that's built to last. They're a straightforward way to get a more connected and responsive feel from your Subaru's rear suspension without a full bushing replacement.
