Perrin engine / motor and transmission mounts are a great upgrade for your Subaru WRX STI. Stock engine / motor and transmission mounts are usually designed with very soft rubber and flex quite a bit. In addition, over time the soft rubber can degrade and become even softer or tear.
Worn out engine and transmission mounts can make your Subaru WRX STI feel "sloppy" and vague. Soft or torn mounts also allow excess engine movement, which can reduce the amount of energy (horsepower) that is able to be transferred to the wheels.
Perrin mounts are designed for maximum support. Each kit has solid mounts with the accompanying bracket. Each kit includes 75A durometer (70A for transmission mounts) bushings and is made from solid 6061 billet aluminum. These mounts are the perfect solution for those that want the best out of their Subaru WRX STI on both the track and the street.
As with all performance engine mounts and inserts, you should also expect to feel a few more vibrations enter the passenger cabin. These vibrations can actually allow you to be more "in tune" with what your engine is doing and how it is performing. As a result you can expect to feel more connected overall to your Subaru WRX STI.
