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
If you’re hunting for a Civic 2013 rear engine mount or Civic Si 2012 rear mount that actually fixes drivetrain slop, this is the one most people end up buying once they’re done experimenting.


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.
If your car is mainly street use, U62A or U70A is the smart call. If the car sees more grid than grocery runs, U88A or U94A will keep the driveline locked down the way you want.

Reliable and Easy to Use Cold Brew Coffee Maker
Color: Black, Size: 40 oz, Color: Black, Size: 40 oz
This cold brew maker is easy to use and does the job well. I get smooth coffee every time without bitterness. The size is good and fits in my fridge without taking much space. The filter works well and keeps most of the grounds out of the coffee. Cleaning is simple and does not take much time. The build feels solid for daily use. I like that I can control how strong the coffee is by changing the water and coffee ratio. One thing to know is that you need coarse ground coffee for best results. (I use Bizzy coffee) Letting it steep longer makes the flavor better. It is not insulated, so you should keep it in the fridge while brewing.

Best cold brew brewer out there
Color: Black, Size: 40 oz
One of my favorite purchases in a long time. This coffee maker is just a perfect size and it can be put in the fridge in any direction, on its side, on its top, whatever. It does not leak and it's very easy to clean. Just a superior product all the way around.

Great cold brew maker!
So far this has been a big improvement from a different brand cold brew maker I had. It is simple and easy to used doesn’t leak. The coffee comes out tasting great! It has a smart design that works well. It’s a great deal for how well it works. It is big enough to last all week but not take up to much space in the fridge.

Air gets trapped in the filter so it won’t fully steep
Color: Black, Size: 40 oz
Filter doesn’t let air out. It’s weird about all these positive reviews bc I tried cold brewing tea two times overnight but the filter holes are so small that basically it traps a large air bubble inside with the tea leaves. The water was barely steeped. It was weird enough to the point where I thought there must be a clear film on the filter that I hadn’t removed. When I loosen the lid all do the air rushes out and it fills w water, but when you tighten the lid any air inside with your grounds/leaves is trapped and prevents steeping. I kept thinking it was me based on all of these positive reviews but I could not prevent the massive about of air from getting trapped in the filter. If they made the holes bigger (not too big to let grounds out but currently you could mistake it for plastic film) then it would’ve been perfect. Nice size and about what I’d drink in a day or so. Change the filter hole size to let air flow out and I’ll buy it back!

Great product, thoughtful design, great customer service
Color: Black, Size: 40 oz
I don't write a lot of reviews, but I felt like this product deserved one. This is an excellent cold brew maker. It is very easy to use and has a great 1,200 mL capacity. The plastic construction is more versatile (less fragile) than other brewers made from glass. The filtration system eliminates the sludge that other brew systems leave. The packaging is very thoughtful - a scoop and sponge are included. The scoop is easily overlooked, but it is the perfect size to clean the used grounds out of the filter. The sponge is an unexpectedly useful form factor to help with cleaning. Hopefully the sponges can be ordered separately, since sponges don't last forever. Some minor downsides: Cleaning is moderately easy, but the only component that is recommended for the dishwasher is the pitcher (which is also easiest to clean by hand). All of the other elements are recommended for hand washing, which doesn't take long. The way the filter is configured, the pitcher will work most effectively if stored (at least for part of the brew cycle) on its side. However, there is a vent in the lid that is prone to leaking when the pitcher is stored on its side. Brewing upright can lead to the top grounds not getting exposed to water. Unfortunately, one of the pieces broke during routine use after a couple of months: the pitcher lid is attached with a couple of hinges that snap the lid into place on the pitcher. One of the hinge attachments broke. I contacted customer service and a replacement pitcher arrived four days later. I'd recommend being careful with these hinge attachments as they seem prone to break. At the same time, the customer service is very responsive and suggests that they take support of their products seriously.
