Aligning my miata and **** is weird.

Passenger side front and rear are good. Drivers rear is good. Drivers front: the camber changes as it pleases. Either -2.0 or -2.6. I can't figure out why it changes between the two. I have noticed that it usually is -2.0 after I jack the car up and lower it down, even though I bounce the suspension. Also have driven the car around the block, and then checked and still gotten -2.0.

WTF is going on?

 

Play in the bushings? Loosely mounted head?

 

If it were play in bushings, wouldn't you expect numbers between 2.0 and 2.6 as well? Those are the only two I have gotten in multiple readings over multiple weeks and even with doing a track day in-between. :-(

Oh, and no head to "mount". It's a DIY digital camber gauge that you have to hold against the rim. Works great. And I checked with the wheel spun at different points, to make sure its not a bent wheel giving me the trouble.

 

ive heard that in the older miatas like 90 or something that the long bolts used for the alignment adjustments go bad. like the notches strip and will move around. this is why i believe that on my car my rear driver side suspension assembly sites slightly higher then all the other corners

 

Newer style eccentric bolts and problem will be solved.

 

The eccentrics aren't slipping. I have them marked, and they haven't slipped yet after 8+ track days and one race.
