My adjustable upper control arms
We fabbed these up today. After going to a wider tire/wheel up front it was a little tough to turn with a depowered rack. We tried to dial the caster back but were gaining too much camber. These should do the trick.

These look amazing. Do they use a stock miata ball joint or something aftermarket?
|
Finally a related thread (so i don't have to start a new one and make my ignorance plainly obvious).
When I bought my NB it had -3.2 as max camber in front and the only mod I can see if a slightly moved lower ball joint. When I had to replace the UCA the max camber was -2.1 on that side. There was a clear difference in the CA length, but I could not see any mod on the old CA. Is there a difference in CA length between NA and NB (so it is NA UCA I had from the beginning)? In that case It's an easy swap to an used NA UCA to get my camber back (doh). (but Keith@FM mentions a difference in Ball Joint...) Going custom (as plain and nice as these look) will solve all problems, this version also look close to stock at a glance (sometimes it's nice to be able to fool the untrained eye). Nice job! :) |

Older thread but I can't understand why someone STILL doesn't make these for sale, it's an autocrosser's dream come true.

Hmmmmm..... |
They do compromise clearance but I'd debate that a 3 degree change from an extended lower ball joint is a better solution. I have a lowered car which has a range of something like -1 to -2 (for round numbers' sake). While I'd like to have a little bit more negative camber adding another -3 isn't going to work.

In any case, my bushings only add 1.5* http://sadfab.com/bushingpackages.html |
An additional -1.5 would be just about perfect for me. Are there different extended lower ball joints? The reason I ask is because the ones I have seen all say they add another 3 degrees. Is your ride height standard?

I run 2.2* of front camber at 4.5" pinch weld heights on my NB street car with extended lower balljoints.
|
Thank you, that helps. I'll go check my pinch height on the front.... I think it's a bit less, but not much but my memory is not trustworthy.

Not sure how people miss that the ELBJs just add ~3° to the range of achievable camber, that doesn't mean you HAVE to run over -3° camber. The geometry difference between standard LBJs and the extended versions means you gain about 3° when you bolt them on but obviously you align the car after installing them. There is plenty of adjustment range to dial camber out. The ELBJs shift the achievable camber to a more useful range, instead of most of the range being useless such as +2° to -2° (I'm guessing on the min. camber, I haven't checked).

I really like this solution as well, one day I'd like to fab up something similar.
