If you lift a couple inches and your stock UCA allows you to align caster within spec then is an aftermarket UCA really required? I thought an aftermarket UCA is only needed if alignment is not possible.
I have driven them and found they were a bit sensitive to PSI and a harmonic hum, after adjusting PSI down slightly they were quieter. Good traction and nice looking tire. It is possible that overinflation caused the noise.
