Enhance your 2006-2011 Honda Civic Si with the Hasport FDRR, a superior rear mount crafted specifically for the K20z3 engine. Designed as a precise replacement for the factory mount, this piece is meticulously engineered to optimize your vehicle's performance.

The Hasport FDRR is constructed from CNC machined 6061-grade aluminum, functioning not just as a mount but also as an effective torque damper. This design significantly improves driving dynamics by offering a firmer and more connected feel to the road. It efficiently reduces excessive engine movement, helping to eliminate traction loss and wheel hop, thus ensuring smoother and more stable handling.

A notable advantage of the Hasport FDRR is its compatibility with aftermarket headers for the 06-11 Civic Si, preventing subframe interference even under heavy load. This mount is an effortless upgrade that substantially enhances your Civic Si's performance and handling.

Bushing Stiffness Options: Hasport offers a range of bushing hardness levels to suit various driving preferences:

• 62A polyurethane, ideal for everyday street use, mimics stock ride quality by reducing engine vibration transfer for a comfortable experience.
• 70A polyurethane, perfect for those who enjoy occasional track days.
• 88A polyurethane, Hasport's stiffest option, is tailored for dedicated track vehicles.
• For the ultimate track performance, choose solid 6061 aluminum mounts.

Note that stiffer bushings increase vibration transfer, which may put additional strain on other car components. Higher durometer bushings are generally not recommended for regular street use.
