Product Details
| Part Number: | FDSTK |
| Brand: | Hasport |
| Position: | Mount Kit |
| Insert Hardness: | 62a |
Upgrade drivetrain control in your 8th-generation Civic Si with the Hasport FDSTK Performance Engine Mount Kit. Designed specifically for the 2006–2011 Honda Civic Si in both 2-door and 4-door configurations, the FDSTK replaces the factory left, right, and rear mounts with Hasport's performance-oriented mounting system.
The factory mounts are designed primarily for comfort and vibration isolation, which allows the engine and transmission to move under load. The FDSTK provides substantially greater control of drivetrain movement, helping reduce wheel hop and transfer power to the ground more effectively during aggressive acceleration.
Reduced engine movement can also improve clearance around aftermarket performance components such as headers, turbocharger systems, and supercharger kits. This can be particularly beneficial on modified vehicles running a taller K24 engine.
Features
- Complete performance engine mount kit for the 2006–2011 Honda Civic Si
- Fits both 2-door coupe and 4-door sedan Civic Si models
- Replaces the factory left, right, and rear mounts
- Helps reduce excessive engine and transmission movement
- Helps reduce wheel hop during hard acceleration
- Provides a firmer, more direct drivetrain feel
- Helps improve the transfer of power to the ground
- Reduced drivetrain movement can provide additional clearance for headers, turbo systems, and supercharger setups
- Particularly useful for modified applications using a taller K24 engine
- CNC-machined from 6061-T6 billet aluminum
- Designed using sophisticated CAD/CAM engineering for strength and proper fitment
- Available with multiple urethane bushing stiffness options
- Suitable for applications ranging from a daily-driven street car to dedicated drag and track builds
- Backed by Hasport's lifetime warranty
Available Bushing Stiffness
- U62A – Street: Most street-friendly option for daily-driven and performance street vehicles
- U70A – Race: Firmer option for aggressive street and track applications
- U88A – Extreme Race: High-stiffness option intended primarily for competition use
- U94A – Most Extreme Race: Maximum urethane stiffness for serious race applications
Higher-durometer bushings provide greater resistance to drivetrain movement but also transmit additional noise, vibration, and harshness (NVH) into the cabin.

Street Use Note
- Performance mounts are intentionally stiffer than factory mounts, so an increase in NVH is normal. For a primarily street-driven Civic Si, the U62A option provides the most comfort-oriented urethane configuration. Drivers prioritizing maximum drivetrain control for competition use can select one of the progressively firmer options.
The Hasport FDSTK Engine Mount Kit is an excellent upgrade for Civic Si owners looking to tighten drivetrain movement, reduce wheel hop, and create a more responsive connection between the engine, transmission, and chassis.

Shipped relatively fast, exactly what I paid for
Mike | August 11th, 2020
Do you want the 62a? Are you driving on the street, like ever? Yes, you do. It holds everything in place much better. Shifting is so much easier now that the engine and trans are not moving. Car feels more connected and lots more feedback.
The only downside for me is that there is a noticeable increase in NVH. I cannot image how much louder a stiffer set would be.
If I was to do this again I would replace the drivers and passenger mount with stock and use the Hasport Rear Mount and Upper Torque Mount that is made for the OEM drivers mount in hopes of less NVH.
There are no install instructions. So if you are not mechanically inclined or know what you are doing beware
Daniel Siebert | October 20th, 2017
Be wary when installing these bad boys that the instructions are out of date that come in the box, and the pictured hardware isn't even the same that they send you (at least was the case for my 09 civic).
Install was around 11 hours of hands on by myself with around 2-3 hours of running around town after bolts would strip, welds broke, it was a mess. The product is good once you get it in, but make sure to start this on a friday night because you won't be done until sunday.
I started with the rear, then front, those are quick and easy.
Drivers side is a bit tougher and the passenger side will break you as a man. Be sure to have some good music or beers before starting this one (or both).
