Porsche 917/10 & Performance Trends Suspension analyzer - Lateral-g Forums

I am building a Porsche 917/10 replica and using Performance Trends suspension analyzer to work out the suspension. I will be deviating from the original as getting the blueprints might be impossible and there may be better designs now days.
Project Overview
2000 lb track car
95" wheel base that is 4.5" longer than stock
Flat 6 mid engine layout. 400 hp
weight dist. 45% front 55% rear
full tube chassis, double A-Arms front and rear.
I've done builds to this extent before but this time I have purchased Performance trends suspension analyzer to see if I can do it better.
How could I post the Performance Trends file so others can look and have input?
Is there any interest in following my progress?
Here is the real deal.

The rear was more like this picture with longer trailing links going forward but I will go with a H shaped lower and an A-arm for the upper. That will work better with a deep backspacing. The Porsche die hards will hate me but I'm building a car for me not them.

Ron Sutton posted shots like this from Performance Trends in my build thread.

He may be able to explain how it was done.

Well I have been playing with the Suspension analyzer and think I can attach the file. If you have Suspension analyzer please try to open it. I was able to click "File" "Save as" "Advanced" and pick a location outside of Suspension Analyzer and save it. Then I was able to open Suspension Analyzer click "File" "Open from floppy drive" and locate the file and open it again. I guess they just never bothered to change the language. I have not had a floppy drive for 20 years. Also I have no idea of the exported file's type but was able to put it in a zip folder to post it here.
So, please if you can open this do so and see if it works. Keep in mind that I am new to the program and this is just a rough start. There are lots of info to be corrected still but I am trying to nail down the basics of the front suspension.
I have read that for a car like this I may want to account for 1" lift and dive and 2 degrees roll for the calculations. Does this sound about right?
