Adjustable Control Arm Bush

I have these installed in my car. The only downside I've seen so far, is everytime you make a camber adjustment, it throws the toe-in adjustment out. Food for thought...

Yep. I am also curious as to whether this item results in a stiffer ride due to there not really being any "rubber" in the mount. I do not have a baseline for comparison, as i changed everything at the same time. i.e. control arm bush, pinion bush, rack mounts, castor bar, sway bar mounts, tie rod ends, ball joints, and added Koni Dampers and stiffer springs. All I know is, when it hits a bump, make sure the harness is on tight and forget about hanging on to the steering wheel!!!
