Description
One of the components of your car that suffers silently with age is the rubber in the suspension bushings. Over time, they break down and allow more movement of the control arms. This makes your handling sloppy and makes the car feel old.
This SuperPro polyurethane bushing set replaces just about every piece of rubber in the suspension. Poly bushings move differently than rubber ones, allowing less deflection and no pre-loading. This means more precise and consistent handling, with a slight increase in sharp impacts.
While it might seem that all poly bushings are the same, that's not true. Our SuperPro bushings use a proprietary polyurethane mix that allows for more precise control with little (if any) NVH (noise, vibration, harshness) increases. They also have details that allow the bushings to retain grease, eliminating noise. This means they won't squeak, ever, and require no maintenance (as long as you use the included grease). How confident are we of this? These include a lifetime warranty against squeaking. Of course, that lifetime warranty includes any failure as well, and there are no disqualifications for track / competition or off-road (!) use.
Includes new bushings for the control arms and stock NA end links (these bushings won't be used for NB end links).
Installation is not trivial - Mazda Miata Performance Projects runs through the process. While regular maintenance with fresh lubricant is required for cheaper poly bushings (which is why we've historically preferred rubber bushings for anything with a license plate), that's not the case with the SuperPro bushings.
These are designed for stock control arms. If your aftermarket control arms use stock bushings, these should fit, but if your control arms are an off-brand, their tolerances might not be as good and fitment might be a bit of a struggle. If you have tubular control arms, be sure they use stock-size bushings - not all do.

Gonna keep this review short.
I replaced my old worn bushings that were on the car since 1996.
These stiffen up the ride a lot. Nice on turns, feels floaty(?) on nice roads much bumpier on crappy roads.
I've been daily driving my miata with these on for about 4 months now and I do not regret getting them. Though I feel that I am more tolerant to a bumpy ride than the average person.
Pushing the old bushings out were more of a hassle than pressing these in. I used a ball joint press and a 2/3 arm puller from O'reillys along with an impact gun to do this job. Took about 24 hours total of frustration because this was my first ever experience replacing these, but it was fun looking back on it and I did learn a lot
Each package of bushings comes with grease and directions, I'm just bad lol
Hey Davin, we're glad to hear that you're happy with these bushings! One thing that isn't talked about much when switching from rubber to poly bushings is that the rubber bushings account for some effective spring rate for that corner of the car. Since poly bushings don't twist and stretch like rubber bushings, there is no preload to the control arms that helps resist changes in ride height (suspension movement). Depending on your shock and spring combo, this may mean that the same car may ride a bit better with slightly heavier spring rates than you were running before switching to poly bushings. Give us a call if you have any questions about this or need any further help. Thanks again!
Very pleasant to drive on. No squeaks unless you hit a very very rough bump. The car feels far more stable and predictable. A caveat to this though make sure you have quality suspension / coil overs as this will emphasize the problems in the road a bit just by their nature. Nothing to be afraid of but you’ll feel the road a lot more. I’m running these currently with Tecna 500/400 spring rates and it’s an absolute pleasure to drive. It’s a must if you want your car to handle and feel better than new.
Install was pretty simple compared to some of the harder bushings out there, threaded rod method is the wisest i have found, hardest part was getting the rear axles out of the hubs..
These bushings are great, but I’m gonna speak on installation here. Do not even bother trying to use a press or vice to do this, because I can guarantee it will not work the way you think it will. Buy a length of threaded rod (I used a 5/8 x 24 inch rod) ,two large nuts, and two large washers (bigger or as large as the diameter of the bushing hole in the control arms and assemble as shown in the picture. This method works incredibly well and the bushings don’t put up much if any fight. They will very much put up a fight any other way. (I spent approximately 5 hours fighting with the lower control arm and a vice with 0 success before I wisened up and made a trip to Home Depot.) Thank you to FM tech support for the idea by the way. Other than that, typically amazing products from FM.
I know what you must be thinking, why change the bushing in a low mileage? The rubber bushings were pushed forward in the control arms rubbing metal against metal. I replaced rubber bushings in another Miata, so I knew how easy poly bushings are to install. I took the car for a shakedown cruise yesterday, I felt a slight difference between rubber and poly, the suspension moves freer with only a tiny bit of increased harshness. The difference in ride quality will fade into the background after several miles. The only question is how long before I must re-grease the bushings.
Our SuperPro bushings have a lifetime warranty, which includes squeaking, and shouldn't ever need regreasing.
