I have honestly never made a video and uploaded it to the internet. Not even with women! I need to play around to see if spring rate balance can accurately be seen on a video. It should be. If it can get to video then that video can be slowed down which would definitely show it. I can probably purposely set up an exaggerated situation where the springs are about as unbalanced as they can get and then film a balanced set. This way you could at least see what to look for. I'm not a videographer though so I have no idea how to do this. I know people that can though. I'll start to work on this but don't expect it to be immediate. Give me some time. I'm about to switch jobs soon so I'm pretty busy.

Most of your balance changes will be affected by the lower shock mount positions. The top locations are for fine tuning and dialing it in. Let's say you have a setup where the back of the car bounces up and down faster than the front. You need to slow the front down. Obviously you could try to use a lower spring rate with the same locations until you find a good set to use. Another way however is to move the bottom shock location inward. This assumes of course that you can. If you can get close this way then you need to move the top over to try to dial it in. Again this assumes that you can move it and that you can find a balance point. The more laid over the shock is, the slower the suspension frequency.

Now lets say you got it close but you couldn't quite get there. The front still moves just a bit faster than the rear and you can't slow it down anymore. Go back to the rear. Try to get the shocks more vertical. You could always move the bottoms outward if possible but this may be too drastic. If for some reason no matter what combo you try front to rear you can not achieve balance, you need to change springs at one end and try again. This is very possible. It is far easier to hit an unbalanced setup than a balanced one.
