I'm not sure if anyone on here is running the emf ball joints, I just bought a set today after bending spicer and mevotech uppers last weekend. They are very nice looking and the machine work is quality, however, the dust boots are hard plastic.
This will be an issue for anyone running caster/camber bushings in the c that put the stud at an angle to achieve the setting.
I am going to pick up a 3/4, 1 ,1 1/4, 1 1/2 and 1 3/4 degree adjusters and be using the highest version that keeps the stud straight as I want as much caster as possible to run pinion angle higher than it is.
I will also be trying to find some rubber dust boots for them.
