SuperPro 04-11 Mazda RX-8 Rear Differential Support Bush Kit - Stainless Hardware

If you're looking to tighten up the feel of your 2006-2015 Mazda MX-5 Miata, especially when you're on and off the throttle, this rear differential center support bushing kit from Superpro is a solid option. The stock rubber bushing can allow for quite a bit of movement in the differential mount, which can make the car feel a little vague when you're accelerating or decelerating through a corner. This kit replaces that soft rubber with a higher durometer material, significantly reducing that unwanted deflection.

By firming up the differential mount, you'll notice a more direct and immediate reaction to throttle inputs. This means better throttle response and a more predictable feel when you're using the gas pedal to help steer the car through turns. Superpro uses stainless steel hardware with this kit for improved longevity. While this higher durometer version sharpens responses, it's worth noting that it may introduce a small increase in Noise, Vibration, and Harshness (NVH) compared to the stock rubber bushing, or Superpro's softer version.
