Powerflex Door Stop Bushings
Includes two bushings in the box, enough for both left and right doors. Fits all generations Miata/MX-5 and Fiat 124.
These bushings replace the factory rubber which connect the door to the chassis. The polyurethane offers a more solid connection than the factory rubber, without the installation hassle/difficulty or difficulty shutting the door that can come with solid delrin bushings.
Brian's notes: No drama, easy install, even instructions included. One error in the instructions, they indicate 2 bushes included and 1 grease pack but actually no grease pack and instructions make no mention of using grease on these. No squeak in our test car and I like these better than the Delrin choices.
These are great and the doors are definitely held firmly in place. I'm still dialing in the adjustment so that my doors don't require slamming but at least now they don't bang around as I'm driving over bumps.
Easy install and the doors sound more solid when closing.
Simple to install. The doors open and close with a more solid feel.
Super easy install. Seemed to reduce door deflection.
