Best Performance Door Bushing for Mazda MX-5 Miata Fits All Years 1990-2022

I installed these per the instructions. Where I had a concern with the install was with the torque specification. 12ft lbs seemed like it was way too much and I have an accurate torque wrench. The material seemed to yield to the bolt heads far more than I was comfortable with, so I ended up torquing them to half that, 6 ft lbs. So far they are staying put and not loosening up yet. I had an issue with the passenger side door cup the bushing fits into. For some reason, it was much bigger than the bushing and would've had too much slop, defeating the reason for having the bushing in the first place. So I removed the door cup from the door, put it in a vise and bent it inward a little with a soft mallet so that the bushing fit nice and snug like it did with the driver's door.These are nicely made and machined and I like the fact they have the door overstrike bump built in, unlike the competitor's products. But where I have a caveat is what the material does as you drive the car. The door receiver cups initially fit the bushings perfectly after installation, no slop. But as I drove around and the body flexed, the plastic has slightly deformed with repeated impacts from the metal door cups, leaving a minuscule gap between the door cup and the bushing. Now I get a slight "clack" noise from both doors if I go over harsh bumps. I don't know if there is a solution for that either. I like how these HAVE stiffened up the body, but that little "clack" may or may not become annoying over time. It does take a pretty good road bump to make the noise however and other components also make noise on the car to be fair to this product. It's just not quite a perfect solution, but they're better than the soft OEM bushings.

The door strikes are brilliant. Some thought went into this one. Thanks!

Easy installation. Doors shut quieter. Car sounds more solid compared to OEM.

My 92 Miata has about 130K, is all original and well maintained. My doors closed well and I never really noticed any rattles in normal driving. But of course 1st gen Miata's have a chassis about as stiff as a wet noodle, so I was very skeptical these would have any noticeable effect. Wow, I was wrong! These were not only stupidly simple to install, but they provided a distinct improvement! Yeah I still have chassis flex but now when I go over washboard rutted roads, the car simply feels a bit more solid. Very hard to describe, but there is no doubt a reduction in NVH. The doors close normally, solid, not harsh. I would definitely recommend these as a worthwhile modification.

My doors used to rattle like crazy of bumps that I driver over every day in my neighborhood, but now they just sound SOLID over those same bumps. The cabin NVH is noticeably improved now that the door rattles are eliminated. These seem kind of pricey over the Craven Speed ones but UMHW material + unique bumper design inspires more confidence over the common delrin material you find at a lower price. Install was easy with no sanding/modfication necessary that others have complained about in competitor products.

As advertised

Everything they say is true.Little pricey, but worth it.

I bought these on a whim and was VERY surprised at the difference I felt in the chassis even after replacing decent factory ones (still 23 y/o). Car felt much better over bumps at speed and felt reduced chatter feeling in corners.
