I see. I'm mostly worried about the lower control arm geometry if I go lower than a 1" drop, but to be honest I haven't taken any measurements yet so it might not be necessary anyway.Roll center adjustment doesn't exist on the Z as the ball joints can not be removed from the control arm.
Not even sure bump steer needs adjusted, it's about perfect.
The only reason I'm concerned about bump steer is from hearing complaints from Fit track guys. The CR-Z may have better steering rack geometry for lowering, I'm not sure. Just out of curiosity, how much lower have you gone than stock?I don't get any bump steer on my setup and 've got quite a bit done to my suspension.
