Another 10-GT3 Corner Weight ?
Just got back from a Roebling Road DE where I had my car weighed with the following results ,with a 1/2 full tank:
LF = 633 / RF = 594 = 1229
RF = 996 / RF = 1005 = 2001
Total =1631 + 1599 = 3230
F/R Bias = 38% /62%
My question for the well informed is: Is this good or bad. Should I have the car corner balanced or is this good enough? I weigh 169 so add that to the left side.
Thanks!

Theoretically you can do better..
Adjusting the height means that different wheel loads on the left and right can be corrected.
At the correct height, the wheel-load differences are within a permissible range, provided that the coil springs have the same installation position (installed spring preload) on each axle. Tolerance 1 mm. Wheel-load differences can be kept as low as possible in conjunction with wheel-load weighing machines. It is ok when a tolerance from right to left on front and rear axle is less than 15 kg.
You should measure with a ready-to-drive vehicle (full tank and tools, washer-fluid reservoir full), and on a level surface.
Adjustments should be made with the axle raised. Taking the load off the wheels makes it easier to make the adjustment (adjusting nuts on the spring strut are easier to turn and will have no signs of damage).
When changing the height/wheel-load, the following must be noted:
• A one-sided height change causes a wheel-load change at the same time. A wheel-load change on one wheel also alters the wheel loads of the other wheels.
• A one-sided increase in the installed spring preload (raising vehicle) increases the wheel load.
• A one-sided decrease in the installed spring preload (lowering vehicle) decreases the wheel load.
• A change in the wheel-load is always transferred diagonally onto the other axle side. This means that if the wheel load on one wheel is decreased or increased, the same occurs on the diagonally opposite wheel.

it's pretty close, though i have rarely exceeded a delta of 5lbs cross wt.

Not very close sometimes require 2-3 corner weights to get the right ride height you want and the correct weight distribution also it is more important to be close in the front L-R than in the rear aslo when doing this it is good to but adjustable end bar links.
