GrimmSpeed transmission mounts are a great upgrade for your Subaru WRX. Stock 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.
These GrimmSpeed transmission mounts will reduce transmission movements and give a more solid shifter feel, increasing driving enjoyment, especially if your existing mount is degraded. Worn out transmission mounts can make your Subaru WRX feel very "sloppy" and vague. Soft or torn mounts also allow excess movement, which can reduce the amount of power and force that is able to be transferred to the wheels. The GrimmSpeed transmission mounts fix all this and improve much beyond the factory level (for example, a GrimmsSpeed mount is 5 times stiffer than the stock Subaru WRX STI mount, and a staggering 16 times stiffer than the stock Subaru WRX one).
GrimmSpeed transmission mounts dramatically stiffen up the feel of your drivetrain, allowing for more predictable shifting and greater confidence during spirited driving, with street or race use in mind. Each mount has a robust 6061 billet aluminum and 304 stainless steel construction, and is perfectly designed for a direct fit. Each mount includes 75A durometer bushings and OEM-inspired studs for a factory style fit. The bushings and mount are specially designed to NOT transmit excessive drivetrain noise and vibration to the chassis. These mounts are the perfect solution for those that want the best out of their Subaru WRX 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.
