The Hasport FG4RR is a high-performance rear mount for 2012-2015 Honda Civic Si models. It is a direct replacement for the factory mount and is engineered to work specifically with the K24Z7 engine.

Constructed from CNC-machined 6061-grade aluminum, the mount is a torque damper that improves driving dynamics by providing a firmer, more direct feel. This Hasport mount helps reduce engine movement, eliminating traction loss and wheel hop.

It is an easy upgrade that will improve your vehicle's overall performance and handling.

Bushing Stiffness Options
Hasport engine mounts are available in four urethane hardness levels: 62A, 70A, 88A, and 6061 solid aluminum.
  • 62A polyurethane is suitable for a streetcar and offers a ride quality closer to stock. It transfers less engine vibration to the chassis for a more comfortable ride.
  • 70A polyurethane is for the customer that seeks to occasionally drive their build on the track.
  • 88A and 94A are the stiffest polyurethane bushings that Hasport offers and are designed with dedicated track use in mind. 

Keep in mind that the stiffer the bushing, the more vibration will be transferred into the chassis. Higher durometer bushings are not recommended for street cars as they will put more strain on all other components of the car.
