SuperPro Rear Subframe Void Filler Kit 2008-2014 WRX / STI
This kit includes SuperPro's 8-piece Subframe insert kit. The OE bushings are large rubber pieces that have voids or hollow portions molded into them. This soft voided rubber keeps the ride comfort high and the road noise low, but also contributes to significant movement of the subframe under load. With this movement comes a changing alignment when you drive your car hard. If you've ever gotten under your car and looked at the subframe bushings themselves replacing the complete bushing is quite a chore. For this reason SuperPro offers these inserts that allow you to simply plug these into the voids in the OEM rubber bushings effectively making them a solid bushing. This also allows you to keep the comfort and noise abatement of the OE rubber material without the negative impact of the bushings flexing and yielding under load. All in all a great bang-for-the-buck upgrade. Unlike other brands SuperPro has designed their inserts to fit all 2008-2014 (2008-2012 base model Impreza) vehicles with a single part number that does not require modification.
Why would I need one of these?
One of the things that draws enthusiasts to a given car is it's dynamic feedback. This kit addresses one of the chief concessions the factory engineers have to build into the car to make it appeal to non-enthusiast buyers, and is another great example of SuperPro addressing a performance improvement without a compromise in quality or NVH.
