Product Information
Overview
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 Rear Motor Mount is the answer.
Our mounts are 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.
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.
Immediately upon your first drive, you'll notice positive changes. On/off throttle transitions become smoother. The drivetrain feels more cohesive. Shifts feel tighter. 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.

Dual Duty Design
The modern enthusiast asks their car to live two very different lives. It has to start every morning, survive traffic, and stay quiet enough to hold a conversation. Then, on demand, it has to feel sharp, confident and absolutely ready to hunt lap times or podiums.
At Happy Racer Development, that tension is not a problem to hide, it's the foundation of our Dual Duty philosophy. From dampers to drivetrain mounts to shifting hardware, every HRD component is engineered to operate across a wide spectrum of use, delivering real performance without sacraficing the ability to actually live with the car.
Refinement without loss of drivability is where Dual Duty truly differentiates itself. Anyone can make a part that feels extreme for a few laps; our goal is controlled, repeatable performance that you can live with every day.
