HRD Precision Machined Subaru WRX/STi Differential Brace - Apex Silver

If you're in pursuit of a tighter feeling chassis that puts power down more effortlessly, you've come to the right place. Our HRD Precision Machined Differential Brace is machined from billet 7000-series alloy for superior strength characteristics, featuring our 80A dual duty durometer bushings, and Titan Frost Ti bushing pins. This component doesn't just look beautiful, it helps in transforming how your WRX or STi delivers power. Engineered for Uncompromising Strength We precision machine our differential brace from 7000-series billet aluminum despite the increased costs associated with the material. Why? Because we've over-engineered this component by choice. When you're dealing with the violent back-and-forth forces placed on your rear differential, especially with higher power builds, maximizing strength comes before all else. Built to OEM+ Specifications We've specified our 80A dual duty bushings for this component after much testing. We found that the combination of this durometer in our poly blend with the overall design of our differential brace yielded the best results. As a result, NVH is only minimally increased from your OEM component while you benefit from keeping your differential locked down in a way that is not otherwise possible. Our differential brace is at home on your daily commute as much as it is chasing the podium. The End Result Integrating our differential brace with your build will bring a much tighter feeling to your drivetrain. You will feel more confidence in your power delivery from the rear, and you'll notice it most of all when attempting to put power down mid-corner. This is a modification for drivers who are chasing the best power delivery possible, complementing our pitch stop and transmission mount. After your first drive, you'll be wondering why you hadn't done this modification sooner.
