Does anyone know if GE8 Fit roll center kits will work on the CR-Z? or of any other chassis that might happen to share the same dimensions?

Also has anyone tried any bump steer correction kits?

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.

I don't get any bump steer on my setup and 've got quite a bit done to my suspension. In a nutshell I've got Spoon fsb, Progress rsb, Spoon rigid collars, BC coilovers, Beatrush pillowball mounts and an Mfactory helical LSD. It's the best setup for me and ride comfort for daily use is pretty decent.

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.

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'm about 1" lower then factory ride height. I have -1deg camber up front and almost -2deg in the rear.

RockAuto was selling a steel variant replacement CR-Z control arm; it's possible that one (or even their aluminum third party replacement) might have replaceable lower balljoints but that would require the investment just to find out and possibly ruining the arm in the process. In 96phoenix's investigation it was determined that the US/NA models OEM Honda aluminum LCA lower balljoints were not replaceable (without destruction) despite RockAuto listing individual lower balljoints for the CR-Z for a while (leading to the question often being asked)

I agree that it would be nice as at factory ride height the CR-Z has basically maxed out to the minimum desirable LCA angle so lowering the ride height even modestly (by 'tuner' standards) puts the leverage angle of the LCA too high, in simple terms.

the Fit steering mounts forward the axle, the CRZ mounts aft-ward of it. I'm about 1.5" lower and don't have any real bump steer.

in my experience it takes a lot more bump to bump steer cars that have the aft-ward mounting location.
