I am planning on corner balancing my car myself because there appears to be nobody in MI that does it so I had to pony up and buy the system myself.

Does anyone have any records of what they were able to get ? I just installed the Bilstein coilovers and I dont have a clue what the corner balancing was prior to that. So I am just curious what I should be aiming for.

Cross weight percentage as close to 50% as possible. Raising one corner effects the corner across and the one on the diagonal. If you raise one side 1/4" and lower the across side 1/4", ride height (center) stays the same but corner weights change. I use dumbbells to simulate the driver. It's probably a closer simulation than I'd like to admit.

tks Slakker, I need to adjust the coilovers tonight / corner balance it and then take it for a wheel alignment and then balance it again which hopefully wont throw off the alignment

I usually just balance and then align. Alignment usually won't affect balance but balance can affect alignment.

Agree. Unless changing castor settings which you can't without different upper strut mount or thrust arm, any toe or camber alignment changes will have a minimal impact on corner balance. Set your ride height to your liking first making sure you are within spec of the coilover. Just because there are threads available doesn't mean you're not outside the limits of the shock. It gives you a measurement range to be within. Then corner balance by lowering(extending) the diagonal corners that are too light until you are at 50% cross. Don't get hung up on side to side and front to rear weight as that can only be changed by moving weight around in the car. Focus only on the cross. The cross percentage the scale will give you represents the left rear and right front. If the percent is less than 50 you need to lower left rear and right front equal amount. If more than 50 raise the left rear and right front.

got to do the corner balancing tonight, with absolutely no modification at all with me in the car it was 49.9% / 50.1%... i got damn lucky lol

Great job Tekkie! Where in MI are you I just put PSS10's on my C2 and am looking to get the alignment done.

Ha! That was easy! Also, contrary to popular belief having weight in the driver's seat makes no difference on corner balance. It's purpose is for adjusting end links on sway bars if you have adjustable ones, and setting weight bias if you have ballast you are moving around. It also can make a very slight difference on alignment but really negligible.

there were differences with me in / out of the seat, but it was not much, 49.7 / 50.3 but I think that wont make much difference lol

OK I should probably rephrase before I start a controversial tangent to this thread. Because of binding in the suspension and standard of error with the scales you might see slight variance but that is insignificant. Corner balancing a car is like fixing a stool that wobbles due to uneven legs. Whether you are sitting on the stool or not makes no difference to whether you fixed the wobble or not.
