yes indeed..

if you use adjustable bushings for camber correction you lose the possibility to run solid controlled bushings
most of them are still in poly or rubber so you don't eliminate any problem ..and the camber correction range is not really interesting usually..

if you can ( not sure if there is some camber adjustable complete control arm a la skunk for EFs ) the skunk style or ball joint type adjusting camber kit is of better quality to what i've tried

on the EF serie my bushings seems to make a more pronounced enhancement than on all other hondas i've tried them on.
i still don't understand why, maybe it's the different geometry that makes the solid uca more important, maybe it's the steering components that benefits more of the control.
