PRODUCT DETAILS
Hasport FG4RR Rear Engine Mount for 2012–2015 Honda Civic Si
If your 2012–2015 Civic Si feels like the drivetrain is slopping around, lazy shift engagement, clunks, or wheel hop on hard launch, the factory rear mount is usually the culprit. The Hasport FG4RR rear engine mount tightens up the FG4 chassis by controlling engine movement, sharpening throttle response, and keeping everything where it belongs when you actually drive the car hard. Honda tuned the OEM rear mount for comfort first. After 10+ years, that rubber turns into a marshmallow. The engine and trans rock back and forth under acceleration, braking, and shifts, which leads to missed gears, extra shock on the other mounts, and that vague “mushy” feel. The Hasport Civic Si rear mount swaps the stock piece for a much more rigid unit with your choice of bushing stiffness, so you can match it to how you really use the car. Hasport has been a go-to name in Honda mounts for a long time, and this FG4RR is a direct bolt-in for the FG4 Civic Si subframe and factory bracket, no weird universal brackets, no hacking.
Key Benefits
- Locks down engine movement during acceleration and shifts so the drivetrain stays in line when you’re on it
- Cleaner, more consistent shift feel because the trans isn’t rotating away from the shifter cables
- Less wheel hop on launches compared to tired OEM rubber or generic replacement mounts
- More repeatable throttle response since the engine isn’t rocking back and forth every time you mat it
- Direct bolt-in replacement for the stock rear engine mount, no cutting, welding, or “universal fit” nonsense
- Built specifically for the FG4 Civic Si chassis, not a one-size-fits-nothing bracket
Precision You Can Actually Feel
The Hasport FG4RR rear engine mount uses proper CAD/CAM development, so the geometry, alignment, and clearances actually make sense in an FG4 engine bay. On these cars, keeping the engine where Honda intended is a big deal, especially if you’re launching hard or running sticky tires. By cutting down engine rotation more than the factory piece, this Hasport Civic Si engine mount helps keep axle angles, exhaust clearance, and shifter linkage geometry much more consistent. In practice, the car feels tighter, more predictable, and more connected, instead of the engine trying to leave the bay every time you clutch-kick it. This isn’t a “close enough, drill a new hole” mount. Hasport builds the FG4RR specifically around the 2012–2015 Civic Si layout, which is why it behaves better than bargain mounts that claim to fit everything.
Urethane Durometer Options Explained
You get four urethane options on this Hasport rear mount for the 2012 Civic and up, all the way to the 2015 Si. Pick wrong and you’ll either hate the vibration or still hate the wheel hop, so it’s worth a minute to choose correctly.
-
62A Urethane (U62A – Street)
Softest of the bunch. Ideal if you daily the car and want a vibration minimizing engine mount that still fixes the worst of the slop. NVH goes up slightly over dead stock, but it’s totally livable for a commuter that still hits a backroad now and then. -
70A Urethane (U70A – Track/Spirited Street)
The “I actually drive this thing hard” Civic performance rear mount. Noticeably stiffer than stock, much better control, but NVH is still reasonable. Good match for bolt-on FG4s, occasional track days, and people who don’t mind a bit more feedback. -
88A Urethane (U88A – Race/Heavy Track)
For aggressive street builds and regular track work. Engine movement is basically gone, shifts feel locked in, and launches are more repeatable. Expect clear vibration at idle and low RPM—this isn’t the bushing for someone hunting luxury-car vibes. -
94A Urethane (U94A – Extreme)
The stiffest Hasport bushing Civic Si 2012 option. Aim this at drag, time attack, or any car that spends most of its life on track or trailer. Maximum drivetrain control, maximum NVH. If you daily your FG4, don’t pretend you’ll love this one.

Where'd that cap go!?
This trimmer works well. I've looked over the one star reviews and I cannot imagine what those people were doing with their trimmers. I've had this device for three months or so. And I like it. It's quiet, and does a good job in your nose and ears.
So after all that you're probably wondering why didn't you give it five stars? I marked it down one because of the shape., and maybe the height. Because they both contribute to this thing falling or being knocked over again and again and again. This devices base is less than an inch across and it about 5 inches high. I keep knocking it over just about any time my hand is anywhere near where it is. Because our fingers naturally curl, I keep knocking this thing over. And while that's not usually a big deal. It has a small cap that shoots off and runs under dressers, tables, chairs, just about anything with a space under it. Mine even went under the fridge one time and the stove on another occasion.
I've decided not to let it get to me, because I like the functionality of the device. That five inch height makes it easy to hold on to. And if I wind up losing the cap. It won't matter.

Pleasantly surprised..
This Nose, Facial & Body Trimmer is really a multipurpose product with all the benefits from all the attachments that are included.
I am very pleased with how neat, clean, and smooth it leaves my skin.
I can carry it with me on the go or use it from the comfort from my own home.
I spray it with a tea tree and alcohol mix to keep it sanitized.
I can give it a 4.5-star rating.
The only suggestion I would make to make a really good product great is having a few more attachments that flexible .
Love it!
