89 328, weight distribution, adj QA1

I want to adjust my ride height a little in the front and found that all QA1 solutions discussed here are for the older 308 and early 328 suspension settings. I called QA1, they have no specific solutions for Ferrari, but they are willing to help if I provide:

Weight distribution front / rear in lbs.
Length of mounting point to mounting point of shock
And type of shock.

I can get 2 and 3, but I need some help on 1. Does anyone have actual numbers in lbs of how much a stock 328 with a full tank of gas, no driver or passenger, would weigh?

My bathroom scale is not going to work for this task.

thanks
