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.

Good quality and value for my son!
Number of Items: 5, Color: Black/Sport Grey/Charcoal, Size: Large
I bought the Gildan Men’s Crew T-Shirts multipack on Amazon for my 12-year-old son, who is on the heavier side and thus sometimes difficult to shop for. Pre-teen kids grow fast and go through clothes quickly, so I didn’t want to spend a lot of money on basics he’ll probably outgrow in a year. These shirts are really affordable, especially for a multipack, and the quality is surprisingly good for the price. The fabric is soft and comfortable, and my son says they feel good to wear all day at school. They’re lightweight and did not shrink after washing. I also like that the shirts don’t get stretched out like some cheaper T-shirts do. The fit works well for him too. They’re simple, classic crew neck tees that can be worn on their own or layered under hoodies and jackets. We’ve used them for school and just everyday wear. Another thing I appreciate is that they’re easy to care for. I just toss them in the wash and dryer and they come out looking fine every time. Overall, these are a great value. If you need affordable, comfortable basic T-shirts for a growing kid (or an adult!), this pack is definitely worth buying.

My husband really likes the quality of these t-shirts. They fit nicely and dont have a sagging neckline as some t-shirts tend to have. The colors are nice and they wash up well. Not a heavy so comfortable for everyday use whether relaxing, doing yard work etc

Great t shirts. They fit great, and are very comfy as an under shirt or just a solid color shirt. Have washed them multiple times and they still hold up good, don’t wrinkle easy, and colors have stayed nice. The fit is great, can definitely be used for work, gym, whatever, just good comfy shirts
