If you have some stock c5z corner weight data, and especially if you have the weights for a 2004 Commerative (hood was CF and lighter by about 12 - 15 lbs.
Please post the weights up & thanks. Before balance weights.

Corner weights, totally stock, for a 2003 Z06 - with full tank of gas and 150 pound driver weight - before adjustments (as requested by you).
LF: 880 lbs
RF: 875 lbs
LR: 797 lbs
RR: 752 lbs
F/R = 53.12%/46.88%
L/R = 50.76%/49.24%
Cross difference = 40 lbs

My 2001 Z06. Full interior but with Cobra Suzuka race seat on driver's side, Hardbar, and harness. No driver, 1/4 tank of gas. I've never messed with ride heights or corner balance on it but when I bought it it was lower than stock.

I bet you go through LF rotors fast too.
Is it possible to corner balance this close to 50:50 F-R and L-R without moving weight around in the car?

Here's my buddy's 2004 Z06 on the scales in the NASCAR tech shed at Daytona.
He was not in the car, I think it was about 5/8 to 3/4 tank of gas.
From top to bottom it's LF, RF, RR, LR.

Safety Car
If you don't have a roll cage, place the car on the scales with you or a weight on the seat. Roof in place if it is not a Z06.
Note readings and ride heights at each corner.
Jack the car from the center of the rear sub frame and remove rear scales and lower the car to the ride heights noted. Check front scales and ride height. Adjust ride to original height if it has changed which you probably won't have to.
Do the same for the rear.
Weigh car again and check ride heights. Adjust corner weights to the original readings with rear adjustment.
This ensures that there is no energy in the frame. From this base, you can move stuff around as best you can to achieve as close to the the numbers shown in the BEZ06's last post as possible.
You may be pleased if you achieve these numbers in another way but you may end up with an energized chassis ( Twisted frame) which will will make shock tuning difficult and alter spring rates.
