Gee ( blush)...thanks for the kind words:
Accurate input is critical to accurate output. Here's some more thoughts from a different thread on this subject. Note the weight affect of a 152 lb driver on the 4 wheels...you can proportion up/down from this "typical" driver weight too, if you wish.
Thanks...

In my opinion, you have the option to add ( or not add) your weight. Remember, the calculator works best if you know the other variables rather well ( vehicle weight and individual wheel weights, for example), ...and most people take a "stab" at the vehicle weight and get close.

If you want to be real anal about it, you can:
-- add your weight...but you'd have to figure how much of this the rear of the car sees. For a 150-152 lb driver.... it affects the four corners of the car this way ( looking down on car):
+62 +11
+50 +28
.... so the rear of the car would ( in total) weigh 78 lbs more than thought...with 50 of that on the left-rear and 28 of that on the right-rear ( USA type seating...not UK).

--- and...you can fudge the numbers to account for the slight left-side bias these cars show..and set your spring angles for this slight variation, too. It depends how accurate you'd like to get... balanced against how "good" the more basic numbers are to begin with ( individual wheel weights).
