2020-03-20 - Miata Extended Lower Ball Joints

Q.
I'd like a value on extended lower ball joints since I'm not seeing these specifically in the BCCR and they are a pretty common aftermarket modification as well as standard on NASA Spec Miata. These are used to reach higher negative camber values similar to offset bushings (5pts per corner). They do not allow you to adjust caster like camber plates (10pts per corner).

Aftermarket extended lower ball joints, used on Miatas to increase negative camber, are 5 points per corner.
