Such a simple idea.

Your doors are held closed by the latch, but they're locked into place with a bracket that slides over a rubber bushing. That makes it easy to align everything, but it means the connection isn't as strong as it could be. In a convertible, the doors provide a surprising amount of structural rigidity if they're properly anchored.

These replace the soft rubber door bushings with a stiff, carbon fiber reinforced nylon replacement. The door is solidly locked into place, allowing it to reinforce the chassis. The effect is of a stiffer car with fewer squeaks. We have measured a 3% improvement in torsional rigidity on a 1990.

This is our third generation design. The new carbon reinforced nylon material  is as strong as the old Delrin version, but more resistant to dents and gouges. It also deflects less than Delrin so there's less chance of a bolt coming loose. We've also made the bushing taller to give 36% more overlap with the door cap. More overlap = less deflection = stiffer car. They're also 40% lighter. And on top of all that, they're 22% less expensive! They're produced in-house on our high-end Markforged printers.

Fits all Miatas.

Installation is quick and easy - simply remove the two bolts that hold the factory rubber in place and replace with this stiff piece. The door does need to be aligned properly, so if your Miata has an exciting history a bit of tweaking may be required. We've installed them in every car in our fleet.

Sold in pairs, enough for one car.

helps with noise

After watching the video I decided to try these bushings on my 2006 MX-5 NC. I do believe the bushings have helped cut down on the noise and vibration. Per the video, I still have a couple more things to do but every little bit helps.

Miata 01 LS, feels firmer but my door rattles

I can't tell if it is working. My door does not feel like it is locked in place. I tried to adjust the tightness and position. It also makes rattling noises too.

Squeak and rattle like an old truck

Put these in my '23, and removed them a couple days later. Every bump is a rattle and loud squeak. They appear to be 3-D printed from ABS. Not sure if they are not intended for the ND, but the offending noises went away as soon as I removed them.

We worked with Clint to refine the design to eliminate the noise, and while we made progress, we weren't able to eliminate it completely. Most cars are great, but a few have issues, so we're continuing to investigate to see how we can improve things.

Note that this are printed out of Onyx, which is a proprietary nylon that's reinforced with chopped carbon fiber.
