Supermiata 863 bushings for 90-05 MX5 Miata

[@jmooch59]

Im sold on both of your products. The NC xida and these bronze insert poly bushings. Sadly I imagine the front lower control arms will not allow enough rotation due to the constrained degree of freedom in the rear mount point. The ND fixed this flaw. You guys do real engineering. It shows. I love it.

[@949RacingSuperMiata]

Thanks. We don't actually offer an NC bushing kit though.

Great video, as for the demo in the end, a picture is worth a thousand words. Hope you can do more showcases like this in the future !

[@fireonmytarget8937]

First time I have ever heard anyone mention spring rate in regards to the stronger rubber bushing. Very interesting!

[@EGGdrums117]

Please do a kit for the 86!! Would be much easier than trying to source a full spherical setup with overpriced control arms

[@joetreen5363]

Outstanding video. Very easy to understand. Thanks!

[@AztekScooters]

So you have to rely on the bronze bushing to maintain a tight enough tolerance against the steel to prevent any play, while also being loose enough to allow the steel to rotate? Also, are these going to come back in stock anytime soon?

[@949RacingSuperMiata]

Discontinued. Sorry!

[@businessman2085]

great, informative video. thank you

[@charlie6299]

Great vid. Do wish they’d work in my offset whiteline uppers.

[@ROGUESPIRIT_]

some times a stock bushing is useful in the rear end of a drift car to allow high powered cars to plant the rear wheels flat to the ground to maintain traction. so actually you're wrong, some times in performance situations you would want stock bushes.

[@949RacingSuperMiata]

Curious how a compliant bonded rubber bushing with intrinsic spring rate will "plant the rear wheels flat to the ground" better than a reduced compliance bushing with no spring rate. The motorsports world clearly has it wrong. On second thought, never mind.

[@zacharytribou2728]

to be honest from an outside educated guess, if I saw a suspension flop that easily I would be a bit shocked because I would feel that if a suspension system that has no friction will feel more responsive loose and harsh while one with more friction would feel more smooth and better for potholes and turning

[@949RacingSuperMiata]

Feelings ≠ data.

[@imnota]

You want the springs and shocks to do the work, if you think about it any flex or friction other wise acts like an added untuned shock or spring, leading to uncontrolled movement of your suspension. Same reason why a stiffer chassis can actually be more comfortable, the springs and shocks are gonna handle it instead of the chassis flopping around

[@travdripdrip382]

Crap i just bought myself a kit of super pro bushings. Got them last week. Was planning on starting over the Christmas/new years break from work.

[@dowardcsp]

I do believe that exact white Delrin bushing has 4 NASA National Championships. PTC, PTE, TTC, TTE.

[@949RacingSuperMiata]

lolirl. I think you are probably correct

[@aleddavies770]

Looks like you have a polybush tea coaster 😂

[@Chilicharger665]

Any plans on a FRS/BRZ kit? The new 2022 models seem to have a near identical suspension, so I imagine it would apply to them too.

[@949RacingSuperMiata]

We plan on doing a kit for the NC Miata first. Possibly a kit for the 86 after that.

[@bnr32marc]

I see this kit is discontinued on the website, any plans to bring them back or do you recommend going with the Whiteline kit? If so, will your bronze sleeves work with the Whiteline kit?

[@tonyv5253]

Love this... question, NVH was mentioned on spherical and rubber, how about for the A63\SM ones? (Say for street\back roads\occasional track use)

[@949RacingSuperMiata]

Tiny bit more buzz with urethane over rubber but far better bump asborption.

[@tonyv5253]

@@949RacingSuperMiata thanks!

[@rigley8830]

Hi, just wondering how suitable this kit would be for a road car? How do they compare to standard rubber bushings? Thanks

[@949RacingSuperMiata]

Better bump absorption with the 863 kit. Our 863 kit will eventually require lube where the rubber OEM kit does not. If you have not already, watch the video for more details.

[@melloyello89]

Emilio, I would never question your ingenuity, but I wonder why this hasn't been done before, I'm assuming cost is the main answer. Maybe it is done on other cars and and I'm not familiar with it. I can't think of any reason that it wouldn't work, I see that there is a company that makes them for 911 trailing arms as well. I know the miata market doesn't have deepest pockets, but I'm surprised I have heard of this application before. Also is this an oil impregnated bronze?

[@949RacingSuperMiata]

DIY and small shop conversion from nylon to 863 bronze bushings has been common in the UTV/ATV market for 20 years. Some BMW and Honda shops started doing it about 15 years ago. Most simply haven't heard of it but the idea has been around for a while.

[@FullAssRacing]

This has been around for around 6 years already for Miatas. However, the person/business selling these was working out of his garage and working occasionally on weekends and couldn't keep up with demand. SM is helping support the demand.

[@949RacingSuperMiata]

Google "SAE 863" to learn more details on the material we use.

[@notmyname781]

What lube is best? (specifically for the bronze bearing part - not the inserting the urethane bushing into the control arms - if the two differs that is)

[@949RacingSuperMiata]

We recommend urethane specific non-migrating grease. Full list on the product page. Kit includes enough for install.

[@lutherblissett9070]

Would oil impregnated bearings (like oilite) not mean you can do away with lubing?

[@949RacingSuperMiata]

We recommend a light coat of motor oil on sleeves when installing to act as a moisture barrier. It will also soak into the 863 material overtime and extend their life. But yes, very little maintenance is required.

[@PTYPTY-jl1yv]

When will they be available again??

[@949RacingSuperMiata]

The kit is undergoing some updates. No ETA. Bookmark the page on the website and just check back or get on our mailing list.

how to remove bushings from oem parts?

[@949RacingSuperMiata]

Shoot us an email and we'll try to help :)

[@samueljgarcia9121]

How would this kit pair with a set of tecna coilovers on an NA? Would these reduce ride quality at all? If adding the diff bushing option to this kit, what engine mounts would you pair with them?

[@949RacingSuperMiata]

Detailed question and a good solution depends on a few variables that you have not stated. Always best to simply email us or give us a call for in depth stuff. [e-mail]

[@brythemiataguy4034]

Why were these discontinued?

[@949RacingSuperMiata]

Too difficult to manufacture. We now offer the Whiteline kit. Fraction of the cost, far easier install, nearly as low friction.

[@JoeEngineer]

Do these bushings require a press to install?

[@949RacingSuperMiata]

Some go in by hand, small ball joint press tool makes it easier. HF or Amazon for the BJ press kit

[@gibblesnbitss]

Hey Supermiata, I noticed the 863 kit is out of stock. Any lead time on when these will be back in stock?

[@949RacingSuperMiata]

No ETA. We're making some updates and hope to have them ready soon.
