Go drive the car some and measure again. As Greg reminds us, the front lower bushings are sticky and need to be exercised to get the car settled again to the point where the weights will be valid.

 

Found this trick corner balance calculator...

This is an endless loop of balancing/aligning. Camber changes will effect corner weights and the reverse is also true. All adjustments have some effect on the others so after several years of doing this loop I began to better understand these relationships. I started using scales on top of the friction plates of the alignment rack with modified rulers hanging from the height measuring points. This process ended the loop method of balancing a race car and saved time. I think there are software packages out now to predict what to adjust inorder to optimise this process.

 

For a street car you do not have to be that critical.
The biggest challenge is the loop of corner balance, drive, corner balance, drive, corner balance, and then say "I'm close enough"!!

Get the corner balance as close as possible (without having the car to low for street use) and then a four wheel alignment.

 

Oh! Found this too!

Pretty cool.
I tried this, but it throws the weight off.
Maybe it's adding for a driver?
I think I've had enough for now anyway.
Ended up closer, but also still have more weight 51.1% on the right side.
LF 933 (24 3/8") RF 933 (24 1/4")
LR 824 (22 3/8) RR 902 (22")
Didn't know about the 1/2 gas thing and probably have close to a full tank.
Can't wait to try it out.
Go away clouds!

 

Marc, This is from my web site:
CORNER BALANCING

I have found that when properly balanced, the spring perch adjustment nuts for most 928s are the same height on each side of the same axle. Apparently Porsche springs are very accurate. I therefore recommend that during ride height adjustments, you make the spring perch height the same on each wheel of the same axle. You may end up with the ride height slightly different from side to side, but the car will be close to corner balanced and the difference will not be visible. Keep in mind that the car is not the same weight on each side (passenger side heavier on LH drive cars) and the sway bars may not be perfect. Also, if you have Louie Ott drop links, un-bolt the lower rod end attachment from the lower control arm during ride height adjustments and adjust the length so that the bolts just slip on when you re-install them.

 

Slantnose, also check and be certain that the scales are all 4 perfectly level, as Greg said. If they're off even a couple mm, it will affect things drastically... A spinning laser level works well, or the low-tech method using a container of liquid with about 10 feet of clear tubing coming out the bottom. You fill the container (keeping the open end of the higher than the container), set the container on the floor about in the middle of the scales, then move to each scale and measure from the top of the liquid in the tube to top of the scale. Shim scale as needed.

Thanks for the input.
Having a tough time...
Didn't think to ask if the scales were level, but they should be close.
That part about each side collars being adjusted the same amount is getting me, too.
For example, the LR is up about a eight turns from the RR, and the RF is turned up more than the LF.
Then the whole right side is lower, but the fronts are equal weights and I cannot add any more to RR because that is the heaviest corner of the car.
I can tell a positive difference driving the car, but it looks terrible and still is not "right".

 

Is it possible to turn the left front and rear down(or, the right side up) equal amounts to get it level? This will not change the corner weights much, just level it from side-to-side. Having that large a difference on opposite corners would mean either the car is bent, or the scales are not level....

 

Yes, I could turn both on the right side up (FL is maxed-out down), but thought that would change the weights.
Guess anything is possible like the car being bent, however still has original paint and nothing looks bad underneath.
