Ride Height Questions

[DavidH]

Engine in, running great. Time to work on some of the odds & ends.
I am planning on replacing the Bushings with Neatrix style in the rear so I took a few measurements after a couple of runs. Got the car level and found a few suprises.

LF - 306mm to Center of Wheel
LF - 159mm to Center of Torsion Bar

RF - 303mm to Center of Wheel
RF - 154mm to center of Torsion Bar

LR - 297mm to Center of Wheel
LR - 287mm to Center of Torsion Bar

RR - 303mm to Center of Wheel
RR - 294mm to Center of Torsion Bar

Questions:
I only have a quarter tank of gas and I didn't put the 220lbs in the front as Bruce A. describes, so the delta of 147mm & 149mm may be a little unrealistic. Plus or minus 2mm on the side appears good though.
On the rear the delta of 10mm and 9mm also looks good to spec with the differential of 1mm almost perfect.
But here's the real kick in the pants, I measured form the lip of the Fender well to the ground and got some stange numbers

LF - 25.875 inches
RF - 26.250 inches
LR - 25.0 inches
RR - 25.625 inches

So what's going on here. I'd like to understand before I change the bushings and really have a mess.

As always Thanks...

Body may not be perfect on suspension from factory. I hope it's not accident damage. Sounds like wild numbers to non-pro. me. My 77 is almost perfect. I did the fender game then measured the suspension like you did. 3/4 tank + driver weight in driver seat is important. I believe there is more of a alignment problem as body drops if you do alignment without adding proper weight of 3/4 tank and driver weight. Somebody will answer with a more educated explanation.

So, it appears to be lower on the driver side To get a more accurate measurement, bounce the corners of the car to get the suspension settled down and see if the measurements get better. I wonder if corner balancing the car could lead to this??
