The Hasport FDRR is a high-performance rear mount designed for 2006-2011 Honda Civic Si models. It is a direct replacement for the factory mount and is engineered to work specifically with the K20z3 engine.

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

An added benefit is that it allows for aftermarket headers on the 06-11 Civic Si by preventing interference with the subframe while under load.

Improving your vehicle's overall performance and handling is an easy upgrade.

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 who seeks to drive their build on the track occasionally.
  • 88A and 94A are the stiffest polyurethane bushings that Hasport offers and are designed with dedicated track use in mind.

Remember 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 car components.
