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!!
