Suspension & Diff Bushing Kit GC

ENHANCED SUSPENSION RESPONSE

Complete set of available STI hardened (aka Group N) suspension bushings for front and rear control arms and rear diff mounting.  Increased rubber durometer (firmness) reduces suspension deflection and geometry change under loads improving handling, traction, and steering response.  Also controls diff movement and torque reactions for more responsive application of power while eliminating clunking or other noises due to excessive driveline movement.

Note that some bushings as indicated are Subaru factory replacements because STI Group N bushings were either never produced or have been discontinued.  We have included these replacement bushings to ensure a complete kit and due to the fact that these applications are quite old at this point and replacement is advisable even to just restore original bushing performance.

These bushings must be pressed in with force to install.  Requires professional installation and special tooling to avoid damaging or tearing the bushings.  RalliSpec can provide installation services.

Like most uprated mounts and bushings you should expect an increase in NVH making the car less comfortable to drive.
