    Default Does this wheel change toe in the corner?

    Is it just me, or does the left rear wheel change toe mid corner?

    Something is going on with that car. Not your typical Miata.

    Mark, what all did you find when you put the alignment on it? Did you find a cause for it being camber challenged in the right rear?

    RR is ok. LR has some issues but not so bad that the car would be trying to kill the driver. Something else is going on.

    Does anyone else see the left rear move or is it just me? I was one martini when I posted this.

    Brett,

    Youtube quality is making it hard for me to tell. Can you email me the original clip?

    Its time for a gopro suspension cam on that wheel.

    More footage. This one includes a little tap I got going into Turn 2. I could almost swear that left rear wheel is moving around in a strange way.

    May be a little tire flex. It kind of has a dirt on the side wall that shows how much it is flexing. But then again seeing that the car moves around with it. It may be more.
    Maybe if you could slow down the video you could see it better.
    That's not a Typo, I just can't spell no so well.

    Bingo. We have a winner. Thanks slodrew.

    Using the attached video file and running it through virtual dub (cool app!) provides some clues. Jogging between frames 6-9 (use 150% view) shows the LR moving in and out.

    Toe in and out? Or a wheelbase change? If it's a wheelbase change, it should be a hub problem, right? Like the axle nut jammed and never got tightened down?

    They do... at least some videos have it.
    You can pick your playback speed.. all the way down to .25.
    Just not sure what the logic is behind it. Most likely what the original file format was when uploaded???

    Settings/Speed/0.25 to 2 !!!

    So that begs the question of what would cause rear toe changes? Wilson says he replaced the subframe so I assume that means there isn't a broken subframe mount. I would be surprised if the hub has broken and Wilson hasn't discovered it.

    How about bad bushings?
