just gotta say I love the info on this!

mine weighs double when the wife is in it lol

Another data point.

2017 1SS 1LE, no driver, slightly more than 3/4 tank, stock car other than 19x10.5/19x11 flow-formed wheels instead of the 20x10/20x11, but the RT660 tires run heavy (only slightly lighter of a setup by about 10lbs):
LF: 928
RF: 1067
LR: 906
RR: 826

Intercomp scales under the SCCA.
-53.5% front.
-1834 left (49.2%)
-1893 right (50.8%)
Should tidy up nice once a human is in the drive seat (mostly LF).
