Garage Star Delrin door Bushings

Replace your old worn rubber bushings with Garage Star delrin door bushings. The Garage Star door bushings will help with chassis rigidity.




Drove the car today with the GarageStar door bushings and I have to say, these things are great!

One of the most immediate things I noticed with these was something I didn’t even have to drive the car to see; audio quality was massively improved with these. The stock 10AE Bose system doesn’t sound terrible anymore! Bass and mids are much cleaner and the bass hits are a lot punchier than before. Night and day difference in regards to that.

As far as drivability goes, I probably noticed the benefits of these the most while going over bumps and highway joints in the road. The doors definitely don’t move at all. These make that signature Miata wiggle and clunking sound virtually disappear over harsh bumps.

As far as NVH:

Noise: Quite the opposite of what I was expecting; a very noticeable reduction in noise overall. Mostly noticeable when going over bumps.
Vibration: Little to no additional vibration from what I could tell. My car is pretty well braced, so your mileage may vary here depending on what level of bracing is installed in your car.
Harshness: Little to no additional harshness. Yet again, this may vary depending on what you have installed in your car.
One thing I will say: these bushings are great for keeping your doors where they need to be while driving, but they are not a replacement for door bars or frame rails by any means. Not really sure where people were getting that idea to begin with, but for what they are, they do their job fantastically well.

Well done Ken!



Installed GarageStar’s new Delrin door bushings today. 4 Phillips screws and a quick test drive later, I’m pretty impressed.

They eliminated most(not all) of my “65mph shimmy” and make the car feel totally solid.

Tested with hardtop installed, bone stock 99 NB with 192k miles. NBs are significantly stiffer than NAs from the get go so I was surprised how effective these little pieces of plastic are.

In the grand scheme of chassis stiffeners, these are pennies compared to all the other options and more effective than all the shock tower bars, Cannon Braces and lower control arm tie bars I’ve ever tried.

Hit up Garage Star to get yours.

I just installed these today on my NB1 daily driver, and I couldn’t be more impressed! Cabin noise is greatly reduced over rough terrain, my car no longer creaks when entering a driveway (I could literally watch my door gap separate prior), and I can affirm that the audio quality has improved with my BOSE/Clearwater setup – much less vibration with lower frequencies. The doors now close with an affirmative clunk that is reminiscent of higher dollar luxury cars.I also test fit them on a few other NA/NB prior to my final install, no need for sanding or modification. If you are experiencing any issues, it is likely that your steel cup has been damaged or bent in your car’s lifetime. Like mentioned earlier, hand tighten to snug, close the door a few times, and cinch it down.Absolutely worth every penny. Hands down one of the best dollar for dollar modifications available for our cars.Great work Ken!!

Garage Star shorty console group buy

Here is a prototype shorty console. The reason we decided to make this is Justin kept removing his center console at track events because he was hitting his elbow on the console. As you can see on this one we had cut the hole out for the power window switch and cut a piece of aluminum to mock up the boot ring and to test fit the switch. Everything is going smooth and should have a final this week and go into production. Aluminum and carbon boot ring will be an option and will be sold separately if somebody wants to use the ring on a stock center console. If you have any questions feel free to email or call. Email is on the contacts page.


Consoles will come in two versions. With and without power windows. If you order a power window version we will cut the hole for factory power windows. NB version will follow soon.


Fill out the form and email it to me.

Stock center console. Just a mock up. Project-G Shift and E Brake boots.


We did some test fitting today. We are planning to make a lip that comes out to cover that hole and use a screw to hold the console down. We will make sure everything lines up and fits correctly.

Also we redesigned the window switch part of the console. We decided to make it all one piece and have only make holes for the buttons so only the buttons will be exposed since the old window switch panel looks like crap.


Garage Star Tire Rack

Some of you have seen some of these photos on the Garage Star Facebook page but Justin just got back from Miata Challenge today with some great feedback on the tire rack. We have been testing it around town transporting wheels but this weekend he had a chance to put the Garage Star tire rack to the test. He drove over 600 miles from Sacramento to Buttonwillow and back without any issues. We plan to make a few small upgrades to the tire rack then go into full production. Pricing will be announced very soon. If you have any questions feel free to email me
