HRD Precision Machined 2012-2015 Honda Civic Si Rear Motor Mount - Apex Silver

The 9th Gen Honda Civic Si has a wonderful chassis that responds incredibly well to both power and drivetrain mods alike. If you've added power to your build, done a few hard shifts, or even had your first track day you've probably noticed a major weak link. With added power, wheel hop becomes more prevalent. During hard cornering, putting down power doesn't feel as it should. When shifting hard, you just feel as if there is a lack of connection.

What you're feeling is both a craving for a more locked down drivetrain, but also the limitations of your OEM rear motor mount. It's designed to balance comfort and performance, with the intention of being an acceptable mass market result. Given you're reading this, it's safe to assume you're an enthusiast looking for something more. The HRD Precision Machined 7075-T6 Rear Motor Mount is the answer.

Engineered for Uncompromising Strength

We designed our rear motor mount from 7075-T6 billet aluminum - a far stronger and more robust alloy than the 6061 that is commonly used. It's over-engineered by choice. When you’re controlling the violent back-and-forth motion of your drivetrain, strength matters. Precision matters. So we machined it to tight tolerances, applied our iconic Apex Silver anodized finish, and chose bushing materials with intent.

Interchangeable Bushings

True to our dual duty philosophy, we include two full sets of bushings with each of our 9th gen rear motor mounts. Our included 65a bushings are an excellent choice for the vast majority of enthusiasts seeking a dramatic upgrade over stock, without introducing excessive NVH. A second set of 80a bushings allow you to turn up the stiffness another few notches, great for dual duty purpose cars or track builds.

An Easy-to-Install Must Have

Ask around on any Honda forum - this is one of the top “first mods” for a reason. It’s affordable. It’s easy to install. And it transforms the way your car feels.

Shifts feel tighter. On/off throttle transitions become smoother. The drivetrain feels more cohesive. You feel more in control - not because the car got faster, but because it now feels like it should have from the start. Tight, connected, and intentional.

It’s the kind of mod that makes you look forward to shifting. That makes heel-toe rev matches feel sharper. Power just delivers to the ground without skipping a beat. You'll fall in love with your car, all over again.
