The factory NB Miata steering rack uses a soft rubber bushing on the driver side mount, which is great for comfort, but not for precision. Over time, that rubber flexes and allows the rack to shift side-to-side, creating vague steering feedback and reduced control, especially on lowered or track-driven cars.
R Theory’s NB Miata Steering Rack Bushings replace that flimsy rubber mount with a precision-machined 6061 aluminum bushing, anodized blue and laser-etched for durability and a clean, elevated look. By eliminating unwanted rack movement, this upgrade creates a more direct connection between your steering wheel and the road.
Expect sharper steering response, improved feedback, and a more solid, predictable feel, all without introducing harshness.
These bushings are a simple, effective way to tighten up your NB's steering system and restore confidence behind the wheel.
