Their awesome, just wish they lasted longer
Was extremely satisfied with the ammount of adjustment these gave me. without me needing to slam the front of my car to acheive my camber goals. However i installed these a little over a year ago and 1 side already has 3/8 of a inch of play and the other almost 1/2 a inch of play. I did what i could by adding grease fittings early in their life to try and extend the longevity but less then 10k miles and no more then 2 small track days later they need to be replaced.

Note from FM: Mario, we did have some problems with the early ones loosening up. Please contact us.

All the Camber!!
I was maxed out at -1.8º of camber up front on my FM springs and Konis yellows. I needed more camber to reduce sidewall wear at autocross. These ball joints look to be very high quality and they bolted right up. I was able to hit my camber targets and am no longer rolling over onto my sidewalls at autocross!

A couple tips from my install experience: Go straight to a ball joint separator. The pickle fork I had wasn't the right size or shape. 30 minutes and no success with the pickle fork vs. a minute with the ball joint separator. The other tip is to install the inboard bolt first. I tried getting it threaded when I had the outboard bolts loosely threaded and it was impossible to get lined up right.

Calculating the change in the position of the Eccentric Bolts
These ball joints sit about 5.5mm further out than the OEM ball joints. The total travel of an eccentric suspension adjusting bolt is just over 1cm or around 11mm, full travel, from one side to the other. So the displacement of the center of rotation of the ball joint is approximately HALF of the full range of travel of the adjusting eccentrics. These dimensions are not listed anywhere in the vendor literature. Since this is necessary to estimate the new position of the eccentrics, and whether or not you have the range of travel there that you need to achieve your goal, I made my own measurements. This 5.5mm or a half turn of the eccentric is important to understand in calculating what change will occur in your suspension. If, for instance both eccentrics have a witness mark that sits dead center in the middle of the range of travel for a given setting, of for instance -0.5 of negative camber with the OEM ball joints, once you install the extended ball joints, to obtain the same -0.5 degrees of negative camber, both eccentrics will then be turned to adjust for 5.5mm, of change. This will place the eccentrics at the limit of travel towards the center line, for the same -0.5mm position. For a Miata NA or NB sitting at stock ride height the range of adjustment in camber is said to be -0.5 degrees to -3.5 degrees. The vendor has a video showing these extremes being measured on an alignment machine, as the eccentric is turned from one extreme to another

New found camber and caster.
At my car's height I could get a max. of -1.5° camber and not much caster either. A far cry from the -2° I was looking for. After installing these ball joints the car will accept ungodly amounts of negative camber and caster and I'm very pleased to be driving a set-up that is perfect for my needs.
Thanks Flyin Miata, a job well done.
