CravenSpeedDoor Bushings Compatible with Mazda NA, NB, NC, ND MX-5 Miata | Made in USA (RED)

Easy to install. Surprising results. Instantly tightens up the structure of the car and reduces rattle and squeaks.

This is expensive for what it is, no doubt about that… but it’s worth it! My Miata always felt bad going over bumps, potholes and uneven road… loose? Floppy? Not sure how to describe it but it almost felt like the frame was being bent… it didn’t feel right. These totally solved it! Now it feels solid like a normal car when going over the same bumps & potholes. Also makes a slightly more satisfying *thunk* when closing the doors.Installation is a breeze, but a few things to note. You’ll want to get the screws tight enough to where it won’t fall, but loose enough that you can still slide it around with some pressure from your hand. Then just close and open your door a few times to get the piece centered just right and tighten it down (I suggest a ratchet for a very tight fit as I heard it can come loose). Shouldn’t take more than 10 mins for both sides and you’re done! I feel like everyone with a Miata should upgrade to this.

All convertibles are suffering from reduced torsion stiffness compared to a coupe due to the missing roof structure.Mazda did a great job designing door cups, that could do much more than just providing a stopper when slamming the doors. But they went only half way when designing the adjacent reinforce rubber bushings.A couple of companies came up with the idea of making much more solid bushings, so the doors would become an integral part of the stressed structure. The idea is brilliant, and CravenSpeed is the one company to come up with the best solution.Why are the CravenSpeed busings the best? They are shaped to fit the door cups as closely as possible. Much better than any other product on the market. The bushings have 4 potential surfaces of contact and the CravenSpeed bushings make full use of all of them. Furthermore, the CS bushings are just a tiny bit softer than the usual Delrin bushings. They can be adjusted easily to fit every door, regardless of tolerances.The outcome is pretty clear: You will end up with a noticeably stiffer car. No more door rattling. Improved steering precision. And all this without any downsides like doors that won't close properly. Get them, no matter what generation MX-5 Miata you are driving!

Seem to be very well made and quality pieces. Fit perfectly with no fiddling. As far as "increasing rigidity" it's negligible as far as I can tell. They do cut down on door noise while driving which is great and the doors make a more solid sound when closing now. Whether it's worth it will be up to the individual but I don't regret the purchase.

I got this for my 2019 MX-5 Miata RF. The doors would rattle when going over train tracks, etc. You do need a 10mm ratchet, and also a screwdriver. It is very easy to install, use ratchet to remove the screws (but keep them, they are used to attach the new bushings.) Then put the new bushings on, and use the screwdriver to reverse the screws before going clockwise, so you can be sure you have the threads aligned. Then use ratchet to get the screws closer to the bushings, just holding them snug, but allowing the bushings some play. Make sure your car is on a perfectly flat surface when installing. Close the car door, to get the actual placement of the bushings correct, slightly tighten the screws, close door again, repeat until bushings are fully screwed in. (There are a few youtube videos showing installation, i am not a "car guy", but i was really amazed at how easy they were to install.) They really work, i have forgotten how the doors rattle, and yes, believe it or not, the car does feel a bit stiffer when turning, etc. An awesome and easy to install upgrade to your Miata, and very well worth it. Definitely check out YouTube videos to see full install.

This is my second set of these - the first I put on my Fiat 124 Spider. However, when I sold it, I didn't have the OEM bushings so I had to let them go. Then, when I got my 2020 MX-5, this was a must-have. I installed them today, and the doors close with a satisfying "thunk" and sound a lot like my old Lexus or Mercedes CLK. These bushing are a bit pricey compared to competitors, but they are super-easy to install and make a huge difference. Others have said these bushings make the body rigidity better, but I am not a "spirited" driver so I can't tell much difference. I recommend them for the more solid feel they give to the car.

This is one of those products that should have been part of the original Miata design. It is such a no-brainer, I can't believe it took so long. People spend good money beefing up their Miatas behind the seats with (real or fake) roll bars and in front by connecting the shock towers. Those 2 areas are already much stronger than the cockpit area. Do those also if you like, but don't neglect the part of the car is actually flexing.I went with the Made in the USA option. The cheap knock offs probably work, too, but I was confident that the product was going to be well worth the money, so I didn't mind paying for guaranteed quality. It is still far away the best "bang for the buck" chassis stiffener available.

I installed one on one side, and left the OEM on the other side to listen, feel, or whatever, if there was a difference… and, to no one’s surprise, there wasn’t. This product is a gimmick, so don’t waist your money.

Al principio no creía que aumentara la rigidez del carro... la verdad es que si se llega a notar una pequeña mejora y le da un toque estético... tardó en llegar pero al final llegó antes de lo programado (2 meses)

These door bushings worked as advertised. I definitely see a tighter Miata over rough surfaces like train tracks etc. Less cowl shake ( I never had much) and stiffer torsional longitudinally on cornering. I was originally skeptical as my OEM bushings were in very good condition (as new). I became even more skeptical when they arrived as they fit no tighter into the slots on the door then the OEM ones. Never the less I immediately installed them and headed out to find the worst train tracks I knew of. Like I said I am skeptical no longer and the bushings are worth every penny.

Ordered these while unsure whether they would make a noticeable difference. Gotta say it does. Not sure why Mazda would not have these on the car right out of the factory.

Mejora la sensación de solidez de las puertas.

Muy buena calidad
