Hasport FDSTK Replacement Engine Mounts for 06-11 Civic Si

Hasport FDSTK Replacement Mounts - 06-11 Civic Si

If you're tired of the excessive engine movement and worn-out stock mounts in your 2006–2011 Honda Civic Si, the Hasport Replacement Engine Mounts are a smart upgrade. These mounts are built to keep your K20 engine firmly in place, giving you better throttle response, more consistent shifting, and a much more connected driving feel. Whether your Civic Si is your daily driver, weekend toy, or track project, these Hasport mounts deliver the stability and reliability the factory mounts can’t match.

Each mount is built to handle the stress of spirited driving, hard launches, and performance mods without sagging or tearing like old rubber mounts. By reducing unwanted engine movement, these mounts also help protect surrounding components and keep the drivetrain aligned under load. If you're looking for a long-term solution to the sloppy feeling caused by worn OEM mounts, this is the setup you want.

These mounts will even work with your K24 upgrade. Simply add the Hasport Universal K Block Bracket or the Honda CRV Post Mount and you are ready to install the K24 in your 8th Gen Civic Si!

Durometer Bushing Options

Hasport offers multiple bushing stiffness levels so you can tailor how your Civic Si drives and feels:

• 62A: Best for daily-driven cars. This softer bushing keeps vibration low while still greatly improving engine stability over stock rubber mounts.
• 70A: A balanced option for street and occasional track use. It increases rigidity without making the car uncomfortable for everyday driving.
• 88A: A stiff, track-focused option designed for maximum engine control. Expect more vibration, but also the sharpest throttle response and most precise drivetrain feel.
