Hasport Rear Engine Mount 06-11 Civic Si

Hasport 8th Gen Civic Rear Engine Mounts - 2006-2011 Honda Civic Si

If your stock rear mount is blown out (or you’re just sick of wheel hop), the Hasport FDRR rear engine mount is the Civic Si engine mount upgrade you’re looking for. It bolts into the factory location on your 2006-2011 Honda Civic Si and ties the K20Z3 to the chassis with way less flex, so you get sharper shifts, more consistent launches, and a more connected feel when you’re on throttle.

This Hasport Civic Si rear mount drops in like an OEM part, but uses much stronger hardware and bushings so it actually controls engine movement. You’ll feel it most on hard 1–2 shifts and corner exit when the stock mount usually lets the engine rock around. Whether you daily your car or you’ve got a track-only 2011 Civic Si Hasport mount setup, this piece keeps the drivetrain locked down and repeatable.

Hasport builds the FDRR from beefy materials, including a solid 6061 aluminum Civic Si mount option for people who really don’t care about NVH. You get proper engine alignment, less slop, and way less drivetrain twist under load. For a basic bolt-on Civic Si torque damper style upgrade that actually works, this is it. Just know: more Civic Si bushing stiffness options = more vibration, so pick the right one for how you use the car.

Durometer Options:

Hasport offers multiple Civic Si bushing stiffness options so you can match ride quality to how you drive:

• 62A (Street / SKU: HAS-FDRR-U62A): Softest Hasport 62A Civic mount. Good if you daily the car and want close-to-stock comfort but still want to get rid of that soggy factory mount feel. You’ll feel a bit more vibration at idle, but nothing crazy.
• 70A (Race / SKU: HAS-FDRR-70A): The popular Civic Si 70A Hasport bushing. Solid for street and weekend track use. Noticeably tighter drivetrain, better launches, still totally livable in traffic. Expect a clear increase in NVH vs stock.
• 88A (Extreme Race / SKU: HAS-FDRR-88A): Stiff Hasport 88A Civic Si mount for track-first cars. Engine barely moves, which helps with consistency on slicks and harder launches. You will feel vibrations everywhere. Your passengers might complain. You probably won’t.
• 94A (Most Extreme Race / SKU: HAS-FDRR-94A): For dedicated track/competition cars only. Maximum stiffness, maximum vibration. Great for a serious Hasport performance mount Civic track build, not great if you sit in rush-hour traffic.
• 6061 Solid (SKU: HAS-FDRR-6061): Solid aluminum Civic Si mount—no urethane at all. This is basically “on/off.” Tons of feedback, zero compliance. Use this if you don’t care about comfort and you want your Hasport K20Z3 rear mount to feel like it’s welded to the subframe.
