65 mph shimmy

[JDM88]

It was never particularly bad in my 96 but since I've put in the Bilsteins and FM springs, well there is absolutely no vibrations or unusual activity (asides from other atlanta drivers) at any speed.

Anyone else get it much?

I had it in my '03 and now in the '05.. It's a Miata curse! :(

Every Miata I've ever driven does this.

The only time I had any kind of shimmy was when I was on season old Falken RT615s with more flat-spots than tread...

The bridgestones are getting to that point.

So they ALL do this? Out of all the cars i've owned, I've never heard of this.

Looks like the NB owners have all had it and the NA owners, only some have had it.

We've had three Miata's in our house and they all do it. It's not horrible, but it's there. Mine has done it with four different sets of wheels and tires and a good alignment. It's just right around 65, she's smooth as can be above or below that.

That sounds like the wife's car. We thought it could be the tires/wheels and the alignment so we had everything checked and it still did it.

RE: 65 mph shimmy

It did it the day I bought it on my test drive. Since we had many Miata's before that, I didn't give it a second thought. It's just how it is.

Yeah, it doesn't really bother me. You'll get used to it after a while.

RE: 65 mph shimmy

RE: 65 mph shimmy

Mine doesn't shimmy at 65, but it's developed a click when I first get it rolling. I'm hoping it's just the axle nuts needing to be tightened and not new axles entirely. I wonder what it is though that makes the Miata shimmy at 65. Chassis resonance?

mine did that before, CHECK YOUR LUG NUTZ

RE: 65 mph shimmy

Checked 'em this morning, tight as can be. Shame, I was really hoping there.

RE: 65 mph shimmy

my 95 started shimmying when I took the tower brace off while installing (and then subsequently uninstalling) the turbo. It drove me nuts on the dragon run last weekend. I will definitely be putting the brace back on.

my 97 did it at about 65 and the '05msm does it at about 70, very slight though.
