Help with setup issues!

[Ol' Toothless]

Hello everyone and A very Happy Yule (Merry Christmas) to you all.
I am using RST instead of Motec though I have the Motec software and I am trying to set up the car with the Nest Session Car Params BUT for the life of me I cannot find any details of the tire sizes Like FL Tire Diameter in mm and the same for the Rear left, also Wheelbase (m), front track (m), Steering Ratio and Steering Lock I think I have sourced info from ACC Results Companion (thank you, Doug Duthie

).
Also information on the Suspension Dampers and gearing lol.
I have read through the manual and was just as confused after I read it as I was before.
Does anyone have any ideas on how to do it!

Does any have any idea how to convert .car document to something I can read and understand then convert back!

Thank you all!

Happy New Year everyone!
