The factory window bushings are made from a low quality plastic that becomes brittle and cracks over time. That’s why older Miatas often have windows that rattle, drag, or just don’t feel right when you roll them up and down.
Our Delrin window bushings are a simple fix that makes a big difference. Delrin is a durable material that resists wear, offers smoother movement with less resistance, and lasts far longer than the original bushings. The result is windows that feel tighter and operate the way they should.
Installation is straightforward and only requires basic hand tools. Once installed, you’ll notice an immediate improvement every time you use your windows.
A small upgrade with a big payoff for every NA and NB Miata owner.
The kit includes two bushings: one for each door.
