Corner Weighing a C6Z with OEM Springs?
Can you effectively corner weigh a C6 Z06 with the OEM transverse leaf springs? I wouldn't think you'd have enough adjustment to shift weight a meaningful amount?

Perhaps we can get David to comment on this thread as well.

Just going by gut feeling here, but it seems to me that adjusting the corner weighting of a car without adjustable end links on the sway bar is not really desirable. For example : It would force weight to be transferred to the left front when you were only trying to add it to the right front.
Would love to get some comments from a few suspension experts.
PS> Of course if you have coilovers this is not an issue.

No, it works fine, just not as easy to do and if the links aren't adjustable you can end up with preload in the bar. That isn't a horrible thing, but in cars with the bars that are lubed, the bar can float to one side if it is preloaded. On cars with rubber mounted bars where the rubber twists in torsion, the bar won't float and it isn't an issue at all.
As noted in the linked post, it is better to remove the front links and adjust the links at the end, but you can still cornerweight with the front bar connected.

Randy:
To the contrary it is the leading forum contributors like yourself that I hope will help me learn more.
Hope I am not offending you or others, simply would like to try and understand the science behind the sport.
Just trying to learn.
For example a little research points out several variables in procedure for adjusting corner weight. A few points other sources point out:
Disconnect sway bar and shocks (if possible)
Changes in ride height in one corner of the car will change the toe and camber settingsHope those on the forum that have the real experience can share their information so others can learn.

It certainly doesn't hurt to adjust weights with fixed sway bars, but you'll never get it fully balanced....something will always be in tension. Since the OEM bars slide side-to-side, they are capable of find a neutral spot over time if it's not too far out.
As for the last question, generally the corner balancing itself doesn't require enough actual ride-height change to effect camber. The goal isn't to actually raise/lower the car, but to keep the height fixed while only changing the preload in each wheel. Sometimes cars are so far off (or the symmetry is way out of whack) that it really changes height/camber, but that is the exception not the rule.

You are just fine learning and having fun. Not arguing about the small stuff
Disconnect the bars, set the weights and then put the bars back on.
We do all the cambers and toe after the rough scale is done. Then go back and tweak it a tick more. Hopefully not back and forth too much.

You'd be suprised to see how much it changes with each adjustment. Even a couple of lbs of air pressure shows a pretty significant difference.
I'm curious to know if the C6 platform is RR weight challenged as much as the C5.
