Upgrade your drivetrain with the Hasport Racing DC5STK Performance Engine Mount Kit, engineered for the 2002–2006 Acura RSX (DC5) and 2002–2005 Honda Civic Si (EP3). Designed as a performance replacement for the factory engine and transmission mounts, the DC5STK helps control excessive drivetrain movement while maintaining the engine's stock placement in the chassis.
Hasport uses advanced CAD/CAM engineering to achieve proper fitment, strength, and durability. The mounts replace the factory left, right, and rear mounting points, creating a firmer connection between the K-Series drivetrain and chassis. Reducing drivetrain movement can improve throttle response, shifting consistency, and overall vehicle feel during aggressive acceleration and cornering.
The standard DC5STK configuration works with RSX and 2002–2011 Civic Si manual transmissions. Hasport also offers multiple polyurethane bushing stiffnesses, allowing the kit to be tailored for anything from a daily-driven street car to a dedicated competition vehicle.

Important Fitment Note:
- DC5STK is intended for manual-transmission 2002–2006 Acura RSX and 2002–2005 Civic Si chassis using an RSX or 2002–2011 Civic Si-style manual transmission. An automatic RSX chassis being converted to manual requires Hasport's corresponding DC5AMC configuration. Element and CR-V FWD/AWD transmissions require a different mount configuration.

the mounts themselves are 5/5, pretty easy install. transmission mount is the hardest with the studs in the way. you can remove them, or just the front one. great fit up, don't have to remove OEM manifold but you do have to unbolt the cat from it and push the cat out of the way to get the 90mm bolt into/out of the rear mount.
-1 star because the kit was missing 3 bolts that said were included on the instructions received with the kit. one of the bolts missing is an m12x1.25x45 which you absolutely NEED. a 12x35 is OEM but the hasport transmission mount is quite a bit thicker than the OEM bracket and the 35mm bolt won't bite enough into the transmission. if you try to torque the 35mm you'll likely shear the threads like I did and have to retap the hole. aside from that you can reuse OEM hardware.

The Hasport mount kit adds that nice bling to the engine bay. Performance wise they do keep the engine nice and firm, a large jump over stock mounts, the excess vibrations really aren't to bad after they've warn in. Cold starts are a pain but treat your car right, let it warm up before you take off! Overall very very satisfied!

The definition of quality. I installed the 70a mounts and there is a little vibration but just tighten up your dash and stuff and it wont bother you once the noise is gone. Wish there was a front mount though

Nice and Firm, makes the engine bay looks cleaner. It does vibrate, the whole front end including dash board. No more tire hop but I'm cool with it. Got the 62 street
