2021-01-01 - Extended Lower Ball Joints

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

Extended lower ball joints are 5 points per corner.
