Hasport warranty with Hybrid Racing support

The Hasport DC5RR is a high-performance rear mount for the 2002-2006 Acura RSX and 02-05 Civic Si. It is designed to replace the stock rear mount in the 02-06 Acura RSX, using the stock transmission bracket. This is a perfect replacement for the RSX kit and 02-05 Civic Si.

The mount is a torque damper that improves driving dynamics by providing a firmer, more direct feel. The mount helps reduce engine movement, eliminating traction loss and wheel hop. The DC5RR can replace the factory mount to enhance performance or replace/ upgrade the rear mount in the Hasport EP3 Civic or RSX kit.

For those who already have the RSX or EP3 mount kit and wish to enhance performance further, purchasing stiffer bushing for the rear mount is available. Upgrading to a stiffer rear mount will balance daily driver comfort and added performance. With a stiffer rear mount than those on the side of the engine, the driver will feel more vibration than having all three mounts be the same. This provides flexibility in terms of performance and comfort depending on the user's needs and preferences.

The complete engine mount kit for the EP3 and RSX can be found here: DC5STK

Bushing Stiffness Options

Hasport engine mounts are available in four different 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, as it will transfer 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 is the stiffest polyurethane bushing that Hasport offers and is designed with dedicated track use in mind.
  • Engine mounts can also be purchased with solid 6060 aluminum for those seeking to build the extreme track dedicated car.

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